The given equation has no solution.
What is equation?
Equation is a statement that show the equality of two expressions connecting by equal sign. for example, 3x - 5 = 20. In this case, 3x - 5 and 20 both are expressions which are connected by equal sign. The two expressions are written on the left side of equal and right side of equal. There are different types of equations such as linear equation, quadatic equation, etc.
The equation is given in the question is 4(x - 8) + 12 = 2(2x -9).
when we find out the solution,
4(x - 8) + 12 = 2(2x -9)
Multiply x with 4 and 2 according to the equation.
4x - 32 + 12 = 4x - 18
4x - 20 = 4x - 18
now, you can see this equation has no solution as the value of x cannot be determined.

Valentina bought 12 puzzles each with the same number of pieces. The total amount of pieces is 19,200. How many pieces are in each puzzle box?
Answer: 1600
Step-by-step explanation:
If there is a total amount of 19200 pieces within 12 puzzle boxes, then we'll have to divide 19200 by 12.
19200 ÷ 12 = 1600.
In conclusion, 1600 pieces are in each puzzle box.
Hope this helps!
Answer:
1,600 pieces per puzzle
Step-by-step explanation:
19,200/12= 1,600
you divide because you have the total amount of puzzle pieces and you have the amount of puzzles so
State the domain and range of the relation below.

c domain = {-2, 1, 2, 4, 5} and range = {-4, 2, 2, 5, 6}
D domain = {-4, 2, 2, 5, 6} and range = {-2, 1, 2, 4,5}
* need help fast *
Answer:
The answer you are looking for is A.
Step-by-step explanation:
Remember, the domain is a set of working x values or all possible inputs of a function or two variable relationship. The range is a set of working y values or all possible outputs of a function or two variable relationship. A two variable relationship with more than one output for each input will not be a function in general but will be refered to as inverse.
Now given a set of coordinates for this relation, coordinates with x and y values or inputs and outputs are generally cartesian coordinates represented by (x,y). This is so we know the working x value for each y value, also making it easier to graph it on a coordinate plane or visualize it. x = domain (input of a function) , y = range (output of a function).
All you have to do is sort the x and y values you are given from the coordinates.
For instance, (-1,2) and (4,5) : domain of -1 and 4 [the x values], range of 2, and 5 [the y values].

Henry drank 2/5 of his water bottle. If he drank 3 cups of water, what was the total amount of cups of water in his water bottle? Solve with a model and a full sentence answer.
Answer:
The amount of cups of water in the water bottle is 7.5.
Step-by-step explanation:
Given that Henry drank 2/5 of his bottle of water, and those 2/5 were distributed in 3 glasses, to determine the total amount of glasses that go into the bottle it is necessary to perform the following calculation:
2/5 X = 3
1/5 X = 1.5
X = 1.5 x 5
X = 7.5
Therefore, the bottle fits 7 and a half glasses of water.
Write an equation of the line in slope-intercept form
(-1,0) (-5,0)
Answer:
if there are no typos, line is y=0
Step-by-step explanation:
slope intercept form is y=mx+b
m= slope
b= y intercept
slope is found by y2-y1 / m2-m1
so using the points (-1, 0) and (-5, 0)
(0-0) / (-5 - -1)
= 0/ -4
= 0
m=0
y=0x+b
plug in a point to find b
0=0*-1 +b
b=0
The line is just y=0

Find the value of r so the line that passes through the pair of points has the given slope.
(12, 10) (-2, r), m = -4
Answer:
The missing value in the ordered pair is 66
Step-by-step explanation:
Given that:
(12,10) and (-2,r)
Slope = m = -4
We have to find the value of r so that the line has a slope of -4.
Slope is the steepness of line which is denoted by m.
Here,
[tex]x_1=12, y_1=10\\x_2=-2, y_2=r[/tex]
Putting the values in slope of line formula,
[tex]-4=\frac{r-10}{-2-12}\\ -4=\frac{10-r}{-14}\\[/tex]
Multiplying both sides by -14
[tex]-4*-14=\frac{r-10}{-14}*-14\\56=r-10\\56+10=r\\66=r\\ r=66[/tex]
The value of r is 66
Hence,
The missing value in the ordered pair is 66

What is the perimeter, in units, of polygon UVWXYZ? Enter your answer in the box.
Given:
Consider the below figure attached with this question.
To find:
The perimeter of the polygon UVWXYZ.
Solution:
All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.
From the figure it is clear that,
UV = 9 units
VW = 2 units
WX = 3 units
XY = 3 units
YZ = 6 units
ZU = 5 units
Now, perimeter is the sum of all the sides.
[tex]Perimeter=UV+VW+WX+XY+YZ+ZU[/tex]
[tex]Perimeter=9+2+3+3+6+5[/tex]
[tex]Perimeter=28[/tex]
Therefore, the perimeter of UVWXYZ is 28 units.

You and your friend are standing back-to-back. Your friend runs 8 feet forward, and then 6 feet right. At the same time, you run 4 feet forward, and then run 3 feet to the right. You stop and throw a football to your friend, who catches it. How far did you throw the football?
Answer:
15 feet
Step-by-step explanation:
you and your friend basically formed two different triangles, and in order to determine the distance that the ball traveled we must calculate both hypotenuses:
triangle 1:
hypotenuse = √(8² + 6²) = √100 = 10 feet
triangle 2:
hypotenuse = √(4² + 3²) = √25 = 5 feet
total distance traveled by the ball = 10 + 5 = 15 feet
Find the particular solution to y ' = 2sin(x) given the general solution is y = C - 2cos(x) and the initial condition y of pi over 3 equals 1 . (5 points)
-2cos(x)
closeIncorrect
3 - 2cos(x)
checkCorrect
2 - 2cos(x)
-1 - 2cos(x)
Answer:
[tex]y=2-2\cos(x)[/tex]
Step-by-step explanation:
We have the differential:
[tex]y^\prime=2\sin(x)[/tex]
With the general solution:
[tex]y=C-2\cos(x)[/tex]
And we want to find the particular solution such that it satisfies the initial condition:
[tex]\displaystyle y\Big(\frac{\pi}{3}\Big)=1[/tex]
So, we have:
[tex]y=C-2\cos(x)[/tex]
Substituting π/3 for x and 1 for y yields:
[tex]\displaystyle 1=C-2\cos\Big( \frac{\pi}{3} \Big)[/tex]
Solve for C. Evaluate:
[tex]\displaystyle 1=C-2(\frac{1}{2})[/tex]
Simplify:
[tex]1=C-1[/tex]
Hence:
[tex]C=2[/tex]
Therefore, our particular solution will be:
[tex]y=2-2\cos(x)[/tex]
Hence, our answer is C

The meaning of (4,22) is Magi had run 4 mike's in 22.5 mins
Have a nice Day , Hope this helped you I would appreciate it if you could mark my answer brainliest
Answer:
No, you are correct for the first one. The meaning of the point (4, 22) is that Magi took 22 minutes to run 4 miles.
Step-by-step explanation:
(4, 22) is written as (x, y) where x is the number of miles Magi ran and y is the number of minutes Magi took.
Thus, when Magi ran 4 miles, she took 22 minutes.

Sam opened a savings account with a deposit of $50. Every month after that, he
deposited $20 more. Is this a proportional relationship? Why or Why not?
Step-by-step explanation:
It is given that,
Sam opened a savings account with a deposit of $50. Every month after that, he deposited $20 more.
It is not a proportional relationship. As initial amount was $50 and every month he deposited $20 more. The ratio is not constant for the deposited amounts.
To make the relationship proportional, he must start with zero balance and then should have deposited $20 every month.

Myra is putting together a puzzle such that every 5 days she places one quarter of the remaining pieces into the puzzle. If she started with a 800 piece puzzle, how many pieces are left to be placed after 23 days? Show the work that leads to your answer
Given:
Initial number of pieces Myra have = 800.
Every 5 days she places one quarter of the remaining pieces into the puzzle.
To find:
The number of remaining pieces after 23 days.
Solution:
Initial number of pieces Myra have = 800.
Every 5 days she places one quarter of the remaining pieces into the puzzle.
It means, she will place the puzzles on 5,10,15,20,25,.. days. she will place the puzzle 4 times before 23 days.
The number of remaining pieces decreasing by [tex]\dfrac{1}{4}[/tex].
Formula for number of remaining pieces is
[tex]y=a_0(1-r)^t[/tex]
where, [tex]a_0[/tex] is the initial value, r is decreasing rate and t is time.
Putting [tex]a_0=800,r=\dfrac{1}{4}[/tex] and t=4, we get
[tex]y=800(1-\dfrac{1}{4})^4[/tex]
[tex]y=800(\dfrac{3}{4})^4[/tex]
[tex]y=800(0.75)^4[/tex]
[tex]y=800(0.31640625 )[/tex]
[tex]y=253.125[/tex]
Approximate the value to the nearest whole number.
[tex]y\approx 253[/tex]
Therefore, the number of remaining pieces is 253.

Given the equation y=-3x+2.5: When x is 1, what value of y makes the equation true? When x is -1.5, what value of y makes the equation true? When y is 8.5, what value of x makes the equation true?
Step-by-step explanation:
when,X=1
y=-3 *1+2.5
y=-3+2.5
y=0.5
when,X=1.5
y=-3*1.5+2.5
y=-4.5+2.5
y=-2
when,y=8.5
8.5=-3*X+2.5
3*X=2.5-8.5
3*X=-6
X=-6/2
X=-3
Hence, the statements are true:
when [tex]x=-1.5[/tex] the value of [tex]y=-2[/tex] and when [tex]y=8.5[/tex] then [tex]x=-3[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]y=-3x+2.5[/tex]
So,
[tex]y=-3 (1)+2.5\\y=-3+2.5\\y=0.5\\[/tex]
When,
[tex]x=-1.5\\y=-3(1.5)+2.5\\y=-4.5+2.5\\y=-2\\[/tex]
when,
[tex]y=8.5\\8.5=-3x+2.5\\3x=2.5-8.5\\3x=-6\\x=-\frac{6}{2}\\x=-3\\[/tex]
Hence, the statements are true:
when [tex]x=-1.5[/tex] the value of [tex]y=-2[/tex] and when [tex]y=8.5[/tex] then [tex]x=-3[/tex].
