Which statement about the number 49 is true
Answer:
F.
Step-by-step explanation:
Prime means that it is only divisible by 1 and itself, and we know that it is also divisible by 7, therefore it is a composite number because it has 1, 7, and 49 as factors.

Raul has 50 coupon books to sell.
The total amount of money Raul will make from selling X coupon books is represented by a function.
f(x)=20x
What is the practical domain of the function?
Answer: Domain: {x : 0≤ x ≤50 }
Step-by-step explanation:
Given: The total amount of money Raul will make from selling X coupon books is represented by a function.
[tex]f(x)=20x[/tex]
Domain is the set of x values in a function for which it is defined.Here, X= Number of coupon books .
Raul has 50 coupon books to sell.
So, 0≤ x ≤50 , as it is possible that non of that book will sell.
Hence, Domain: {x : 0≤ x ≤50 }

Determine the two closest integers for each irrational number.
the square root of 19
the square root of 50
the square root of 117
Answers:
a) 4 and 5b) 7 and 8c) 10 and 11=====================================================
Work Shown:
List out the perfect squares
{1,4,9,16,25,36,49,64,81,100,121}
We stop once we reach 117 or just a bit higher.
---------------------------
Then notice that
[tex]16 < 19 < 25 \ ... \ \text{19 between the squares 16 and 25}\\\\\sqrt{16} < \sqrt{19} < \sqrt{25} \ ... \ \text{ apply square root to all sides}\\\\4 < \sqrt{19} < 5[/tex]
Which shows [tex]\sqrt{19}[/tex] is between 4 and 5. Therefore, the two closest integers to [tex]\sqrt{19}[/tex] are 4 and 5.
---------------------------
We follow the same steps for [tex]\sqrt{50}[/tex]
So,
[tex]49 < 50 < 64\\\\\sqrt{49} < \sqrt{50} < \sqrt{64}\\\\7 < \sqrt{50} < 8[/tex]
So the square root of 50 is between 7 and 8.
---------------------------
And finally,
[tex]100 < 117 < 121\\\\\sqrt{100} < \sqrt{117} < \sqrt{121}\\\\10 < \sqrt{117} < 11[/tex]
---------------------------
Using a calculator, we find that
[tex]\sqrt{19} \approx 4.36[/tex]
[tex]\sqrt{50} \approx 7.07[/tex]
[tex]\sqrt{117} \approx 10.82[/tex]
which helps confirm our answers.
what is the equation of a line parallel to y=3x-2 and goes through the point (-1,1)
Answer:
y = 3 x − 29
Step-by-step explanation:
First, let's find the slope of the line
y = 3 x + 2
As the equation is already in slope-intercept form
y = m x + c
Slope = 3
Let a point ( x , y ) be on the new line.
By finding the slope again,
y − 1 x − 10 = 3
y − 1 = 3 ( x − 10 )
y − 1 = 3 x − 30
Which can then be converted to different forms:
Standard form:
3 x − y = 29
Equation form:
3 x − y−29 = 0
Slope-intercept form:
y = 3 x − 29

solve simultaneous equations 4x+2y=7
3x-5y=-24
Answer:
x= -1/2
y= 4.5
Step-by-step explanation:
4x+2y=7
3x-5y=-24
First either make the x or y's the same. It is easier here to make the y's the same.
Multiply each of the first equation by 5 and the second one by 2.
x5 4x+2=7 x5 = 20x+10y=35
x2 3x-5y=-24 x2= 6x-10y=-48
20x+10y=35
6x-10y=-48 +both equations
26x=-13
/26
x=-1/2
Now substitute to find y.

y= 4.5

Step-by-step explanation:

all you need is in the photo
Answer:
slope is -1, y intercept is 5
Step-by-step explanation:
slope formula is y1-y2 over x1-x2
plug in formula
u get the slope is -1
Answers:
Slope = 4
Y intercept = 5
======================================================
Explanation:
Start at the point (-1,1) which is one point on the line. Then move up 4 units and to the right 1 unit to get to (0,5). This is another point on the line.
Therefore the slope = rise/run = 4/1 = 4.
You could also use the slope formula m = (y2-y1)/(x2-x1)
---------------
The y intercept is 5 since the line crosses the y axis at this location. More specifically this is the point (0,5). For any y intercept, x = 0.
The equation of this line in slope intercept form is y = 4x+5. Compare it to y = mx+b and we have m = 4 as the slope and b = 5 as the y intercept.
Find the slope of line:6x+3y=21
Answer:
-2
Step-by-step explanation:

Bring the equation to y=mx+c form
3y=21-6x
y=-2x+7
When comparing, m=-2
Slope m=-2
When the light turns green, Mark accelerates straight down the road at 1.8 m/s2 for 8 seconds. What is his final velocity at the end of those 8 seconds?
Answer:
Mark's final velocity at the end of the 8 seconds is 9.6 m/s
Step-by-step explanation:
The acceleration of mark after the light turns green, a = 1.8 m/s²
The time duration of the motion with the 1.8 m/s² acceleration, t = 8 seconds
Mark's final velocity at the end of the 8 seconds, v is found using the equation of motion for velocity as follows;
v = u + a × t
Where;
u = The initial velocity = 0 m/s
a = The acceleration = 1.8 m/s²
t = The time in motion = 8 seconds
Substituting gives;
v = 0 + 1.2 × 8 = 9.6
Mark's final velocity at the end of the 8 seconds, v = 9.6 m/s.
Final velocity after 8 second is 64 m/s
Final Velocity of car:Given:
Acceleration of mark = 8 m/s²
Time taken = 8 second
Find:
Final velocity of mark
Computation:
v = u + at
v = 0 + (8)(8)
v = 64 m/s
Final velocity of mark = 64 m/s

Miguel selects five DVDs to purchase. A few of the DVD cases appear to be damaged, so the manager gives Miguel a 20% discount on his entire purchase. Miguel tries to guess how much money will be deducted from the total cost. What is the cost of the DVDs before tax is added? Show your work.
Answer:
d * 0.20 = x
Step-by-step explanation:
In order to calculate the total cost of the DVD's we first need to change the percentage of the discount that Miguel's manager is giving him into decimal format by dividing the percentage by 100 like so...
20 / 100 = 0.20
Now that we have the decimal value we can multiply it by the actual cost of the DVDss to find the total cost before taxes. Since we do not have the actual DVD cost we would make the following equation where x is the final total cost and d is the initial cost of the DVDs.
d * 0.20 = x
Part D
Compare your answers in parts B and C. Did your predictions for the coordinates of the reflected images match the actual results? Why or why
Answer/Step-by-step explanation:
Yes, it did because the coordinates of the other polygons would be a direct opposite of polygon ABCD depending on what line it reflects off of. If it reflects off of the y-axis then they would be the same coordinates, just that the X values of the coordinates would now be positive, for the reflection of the x-axis it is also the same except that now the x value would now stay negative while the y values would now be positive. For y=x, it is different because now the X, and Y place values now switch (for example, (-3,-2) would now be (-2,-3)). For y=-x, the place values would both switch, and now be positive.
PS; PLATO does not have an answer this is my personal answer since I am also on this assignment.
Sorry if this response is late! Hope you did well! :)
The coordinates of the reflected images match the actual results because of the following reason.
What is coordinate?Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane. A coordinate plane has four quadrants and two axes: the x axis (horizontal) and y axis (vertical).
Yes, because the coordinates of the other polygons will be in opposite of polygon ABCD depends on what line it reflects off .
Suppose if it reflects off of on the y-axis then the coordinates will be same, only the x- coordinate will be positive.
and if the reflection of the x-axis, the coordinate will be same only the y- coordinate will be negative and the x- coordinate remain positive.
but, For y=x it is different because now the both the x- coordinate and the y- coordinate will be switched with their sign.
