Given f(x) = x – 10, what is f(–7)?A.
–17

B.
–10

C.
–7

D.
–3

Answers

Answer 1

Answer:

Answer: A. $-17$

Step-by-step explanation:

Here, the given function is,

$f(x) = - x - 10$

By substituting x = -7

We get,

$f(-7) = -7 - 10$

$\implies f(-7) = - (7+10)$

$\implies f(-7) = -17$

Thus, the value of $f(-7)$ is $17$ .

⇒ Option A is correct.

Answer 2

Answer: easy
put -7 for every x
f(x)=x-10
f(-7)=-7-10
f(-7)=-17

A

Cristina bought a bag of coffee for $8.47. The weight of the bag was 7/8 of a pound. What was the price, per pound, of the coffee?

Answers

~For this problem, you need to divide.
~The easy way that I think might help you is if you change the fraction into a decimal.

$(7)/(8) = 0.875$

Now divide $8.47 by 0.875
$(8.47)/(0.875) = 9.68$

The price per pound of the coffee was $9.68

$8.47/ (7/8 pound)= $9.68/pound.

The price of the coffee is $9.68/pound~

Are the graphs of the lines in the pair parallel? Explain.Find the slope of a line parallel to 5x + 2y = 6

Answers

To make it easier turn this equation into a slope. To do that you must get "y" by itself on one side of the equal sign. The "y" have to be positive. Then plot it out. Enter the "x" (1 for example) in the equation and solve to get "y". Then use the ordered pair to plot out the slope. Then you find a coefficient of "x" that matches the one in this equation and plot that out. If it's parallel then it's right. :)

The GCF of 135, 225, and 270 is 45.

The GCF (Greatest Common Factor) is the largest number that divides evenly into two or more numbers. To find the GCF of 135, 225, and 270, we need to find the common factors of the three numbers and choose the largest one.

The factors of 135 are: 1, 3, 5, 9, 15, 27, 45, 135.

The factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, 225.

The factors of 270 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270.

The common factors of 135, 225, and 270 are: 1, 3, 5, 9, 15, 45.

The largest common factor is 45. So, the GCF of 135, 225, and 270 is 45.
