Evaluate the expression when x = 4
-4x + 1.5x - 2.5 - 2x -6.5
A simple algebra equation!
You have to replace each x with 4, so the equation would look like this:
-4·4+1.5·4-2.5-2·4-6.5
Evaluate the terms, you get:
-16+6-2.5-8-6.5
Then you add and subtract where needed:
-10-16 = -27
And that's the final answer!

the lager of two numbers is 10 less than twice the smaller number if te sum of the two is 38 find the largest number
Answer:
22
Step-by-step explanation:
a=larger number b= smaller number
a=2b-10, a+b=38
2b-10+b=38
3b=48
3b/3=48/3
b=16
a+16=38
a=38-16
a=22
Write an equation in slope intercept form that passes through the point (-4,2) and is perpendicular to y=2x+2.
Answer:
Step-by-step explanation
Perpendicular lines have slopes that are negative reciprocals of one another.
so, in this case, the given slope is 2.
The negative reciprocal of that would be -1/2.
so far, our equation looks like: y=-1/2x+b
now, take the point given to us, (-4,2) and plug it into the y and x values.
2= -1/2(-4) +b
2= b+2
b=0
Our y intercept is zero, so our final answer will be:
[tex]y=-\frac{1}{2} x[/tex]
Monica has $20. she needs to buy a gallon of milk that costs $2.50. she also wants to buy yogurt, which costs $1.20 a cup. which inequality can you use to find the number of cups of yogurt monica can buy? 1.20x 2.5 greater-than-or-equal-to 20 1.20x 2.5 less-than-or-equal-to 20 1.20x 2.5 < 20 1.20x 2.5 > 20
The inequality which is used to find the number of cups of yogurt Monica can buy is,
[tex]1.20x+2.5\leq20[/tex]
What is the inequality equation?Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Monica needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. Let suppose the number of cups of yogurt bought by Monica is x.
As she has only $20. Thus, the inequality expression which can be used for this condition is,
[tex]1.20x+2.5\leq20[/tex]
Solve the above equation and find the value of x,
[tex]1.20x\leq20-2.5\\1.20x\leq17.5[/tex]
Divide both side with 1.20,
[tex]x\leq\dfrac{17.5}{1.20}\\x\leq14.58\overline3[/tex]
Hence, the number of cups she can Monica is 14.
Thus, the inequality which is used to find the number of cups of yogurt Monica can buy is,
[tex]1.20x+2.5\leq20[/tex]

Eric made $289 for 17 hours of work.
At the same rate, how many hours would he have to work to make $ 119?
Answer:
7 hours
Step-by-step explanation:
You would divide 289 by 17. You get 17. Then you would divide 119 by 17 and you get 7
Answer:
7 Hours of work to earn $119
Step-by-step explanation:
You would divide $289 by 17 hours to find your hourly wage. You would find the hourly wage to be $17 an hour. Then you would take $119 and divide it by $17, and you'll find the number 7, this is your hours of work you have to work to earn $119.

========================================================
Explanation:
A full circle of radius r has the circumference of
C = 2*pi*r
A semicircle will have us divide this value in half
2pi*r turns into pi*r
The curved distance along the top is roughly pi*r = pi*5 = 3.14*5 = 15.7 cm.
Add this onto the straight line distance along the bottom to arrive at 15.7+10 = 25.7 cm

Carlos took seven years to pay off his loan by making identical quarterly payments. the loan had a principal of $22,375 and 5.49% interest, compounded quarterly. carlos paid a total of $28,821.67. how much did carlos pay in service charges? round all dollar values to the nearest cent. a. $1,721.31 b. $4,725.36 c. $1,670.98 d. $6,446.67
The Carlos pay in service charges is $1721.3
We have given that the Carlos took seven years to pay off his loan by making identical quarterly payments.
The loan had a principal of $22,375 and 5.49% interest, compounded quarterly.
P=22375 and interest rate =5.49%
Carlos paid a total of $28,821.67.
We have to find how much did Carlos pay in service charges
First we find the monthly payment of the loan
What is the formula of monthly payment?The formula for monthly payment is,
[tex]M=\frac{amount}{discount}[/tex]
Discount factor
[tex]P=\frac{1-(1+i)^{-n}}{i} \\[/tex]
Where, Amount = $22,375 and r=0.0549 and compounded quarterly therefore n=4
[tex]i=r/n=0.0599/4[/tex]
i=0.0137
Time =7 years
[tex]n=4\times 7=28[/tex]
Now put all the values in above formula we get
[tex]P=\frac{1-(1+0.01372)^{-28}}{0.01372}\\\\P=\frac{1-(1+0.1372)^{-28}}{0.01372}\\\\P=\frac{1-0.6827}{0.01372}\\\\P=\frac{0.3172}{0.01372}\\\\P=23.11[/tex]
Monthly payment,
Use the value in the formula of monthly payment
[tex]M=\frac{22375}{23.1177}[/tex]
[tex]M=967.871[/tex]
The payment he has for for 7 years compounded quarterly that is for 28
Therefore the payment,
[tex]Payment= 967.871 \times 28 = $27100.39[/tex]
[tex]Service charges = Total payment - payment[/tex]
[tex]= $28,821.67 - $27100.39[/tex]
[tex]= $1721.27[/tex]
Therefore, Carlos pay in service charges is $1721.3

You work with a carpenter who asks you to cut trim board in the following lengths: 71/2 inches,
101/2 inches, 9 inches, and 51/2 inches. To do this using only one piece of trim board, how long
must the board be?
Length of board will be 32 1/2 inch.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
Length of board after cutting are;
7 1/2 inches, 10 1/2 inches, 9 inches, and 5 1/2 inches.
Now, Total length of board is calculated as sum of all cut lengths.
So, Total length of board = 7 1/2 +10 1/2 + 9 + 5 1/2
= 15/2 + 21/2 + 9 + 11/2
= 47/2 + 9
= 65/2
= 32 1/2
Thus, Length of board will be 32 1/2 inch.

Answer:
C 13
Step-by-step explanation:
2 right-angled triangles. so, Pythagoras applies for both.
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle).
starting with the small triangle we have
5² = 3² + x-part²
x-part² = 5² - 3² = 25 - 9 = 16
x-part = 4 cm
the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.
that means
x = 2 × x-part = 2 × 4 = 8 cm
for the large triangle we then get
y² = x² + 15² = 8² + 225 = 64 + 225 = 289
y = 17 cm
and so,
y - x = 17 - 8 = 9
but that is not an answer option.
and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.
in essence, x is what I originally called "x-part".
so, the Pythagoras calculations remain basically the same, but we should name things differently like
5² = 3² + small-side²
small-side = 4 cm
x = small-side = 4 cm
long-side = 2 × small-side = 2 × 4 = 8 cm
y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289
y = 17 cm
and the actual y - x = 17 - 4 = 13 cm
There is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answer:
Step-by-step explanation:
The first probability of it being red = 5/11
The key to the question is that you replace the red marble you took out. So there are still 5 red marbles.
You still have a 5/11 chance of getting a red marble.
P(red + red) = 5/11 * 5/11
Answer
P(red + red) = 25 / 121
what is the range of this piecewise function
Answer as a compound inequality: [tex]-4 \le y < 2[/tex]
Answer in interval notation: [-4, 2)
=============================================
Explanation:
The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.
The lowest point occurs when y = -4. We include this value. So far we have [tex]y \ge -4[/tex] which is the same as [tex]-4 \le y[/tex]
The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that [tex]y < 2[/tex]
Combine [tex]-4 \le y[/tex] and [tex]y < 2[/tex] to get the compound inequality [tex]-4 \le y < 2[/tex]
This says y is between -4 and 2, including -4 but excluding 2.
To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

Answer:
HOPE THIS HELPS
Step-by-step explanation:
You need to first plot the points on the graph.
Since, it says you need to reflect across x axis, you need same number of square units.
For example, P has the coordinates( -2,3 ). -2 lies on the x axis, so the point doesn't go neither left nor right. It is 3 squares above the x axis, so the reflected point should be 3 squares below the x axis. Likewise, you can do the other points.
Hope it helps :)
