Pls help I would appreciate it

How do I solve this equation 144=-12(x+5)

Papessa [141]

First you distribute the -12 to the (x+5) getting 144=-12x-60.

Next you add 60 to each side getting 204=-12x

Then you divide each side by -12 getting -17=x, which is the answer.<span />

Let f(x) = |x|, where x can be any real number. Write a formula for the function whose graph is the

andrew11 [14]

Answer:

y = 5f(x)

Please see the picture below

Step-by-step explanation:

Given the function f(x) = |x|, to transform the function y=f(x) with a vertical scaling with scale factor of 5, you should multiply the function by 5 to obtain the result;

y = 5f(x)

Please see the picture below to see a graphic solution.

A semicircle is attached to the side of a rectangle as shown.

laiz [17]

Answer:

$58.8\ mm^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle plus the area of semicircle

step 1

Find the area of rectangle

The area of rectangle is equal to

$A=bh$

where

$b=9\ mm\\h=3\ mm$

substitute

$A=(9)(3)=27\ mm^2$

step 2

Find the area of semicircle

The area of semicircle is equal to

$A=\frac{1}{2}\pi r^{2}$

we have

$r=9/2=4.5\ mm$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$A=\frac{1}{2}(3.14) (4.5)^{2}$

$A=31.8\ mm^2$

step 3

Find the area of the figure

$A=27+31.8=58.8\ mm^2$

Jake’s measures the height of a tree to be 74 3/8

goblinko [34]

I'm assuming the question is asking how tall the tree is if it has grown 2 3/4 inches.

The initial height of the tree is 74 3/8 inches and it grows 2 3/4 inches after six months. We can add these two numbers together to calculate the height of the tree now.

$74\frac{3}{8} + 2\frac{3}{4}$

Since these are both mixed numbers, we must find a common denominator to add our fractions. 8 is the lowest common denominator for 4 and 8. So:

$74\frac{3}{8} + 2\frac{6}{8}$

We can now add our whole numbers up (74 + 2) and add the numerators of the fractions together to get a single fraction ( $\frac{3}{8} + \frac{6}{8}$ ).

74 + 2 = 76

$\frac{3}{8} + \frac{6}{8} = \frac{9}{8}$

Putting these two together, we get $76 \frac{9}{8}$ , which is equal to $77\frac{1}{8}$ .

We can also turn this answer into an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator. So in this case:

77 x 8 = 616

616 + 1 = 617

The denominator stays the same, so our answer as an improper fraction would be $\frac{617}{8}$ .

So the tree is $77\frac{1}{8}$ inches tall, or $\frac{617}{8}$ inches tall.

Find the value of 7 + 32 (-5 + 1) ÷ 2.<br> A. 25<br> B. 32<br> C. -11

kobusy [5.1K]

Answer:

as written, -57
as perhaps intended, C. -11

Step-by-step explanation:

The expression shown evaluates as ...

7 + 32(-5 +1)/2 = 7 +32(-4)/2 = 7 -128/2 = 7 -64 = -57

_____

If we assume your "32" is supposed to be 3², or 3^2, then the expression evaluates differently:

7 +3²(-5 +1)/2 = 7 + 9(-4)/2 = 7 -36/2 = 7 -18 = -11 . . . . matches choice C

_____

When in doubt, you can have the Google calculator evaluate your expression. However, you do have to write it properly and with all the required parentheses.
