Answer:

$\huge{ \boxed{ \sf{19}}}$

Step-by-step explanation:

$\underline{ \sf{Given}} : \sf{y = 12}$

$\underline{ \sf{To \: Find}} : \sf{Value \: of \: the \: given \: expression}$

$\sf{y + 7}$

plug the value of y

$\mapsto{ \sf{12 + 7}}$

Add the numbers: 12 and 7

$\mapsto{ \sf{19}}$

Hope I helped!

Best regards! :D

Please HELP!!!!!!!!!

Calculate the sum

5x - 10 + 7 = 65 - 20x + 32

Move terms

5x - 3 = 97 - 20x

Collect the like terms and calculate

5x + 20x = 97 +3

Divide both sides by 25

25x = 100

X= 4 ANSWER

I skipped some steps because it would be too long :/

Multiply parenthesis by 8

20x>8(4x - 5) -20

Calculate

20x>32x - 40 - 20

Move variable to the left

20x>32x-60

Collect like terms

20x - 32x > -60

Divide both sides by -12

-12x>-60

You may remember that the perimeter of a rectangle is P=2(W+L) where W is the width and L is the length. Suppose that the perime

Anna71 [15]

Answer:

5 feet

Step-by-step explanation:

P = 2(w + l)

P = 34

l = w + 7

34 = 2 (w + w + 7)

34 = 2w + 2w + 14

34 - 14 = 4w

20 = 4w

w = 5 feet

Since l = w + 7

l = 5 + 7

l = 12 feet

ABC High School is debating whether or not to write a policywhere all students musthave uniforms and wear them during school hou

larisa [96]

If 45% don't want uniforms, it means that 45 out of 100 students don't want them, so the probability is 45/100 = 9/20

And 55% want unifrms, so the probability = 55/100 = 11/20

The point ( - 14,12) is on the graph of y = f(x). Find the corresponding point on the graph of y= qe), where gex) = arcus.

liubo4ka [24]

Answer:

$(-14,4)$

Step-by-step explanation:

Given

$(-14,12)$ $\to$ $y =f(x)$

$g(x) = \frac{1}{3}f(x)$

Required

The corresponding point on $y = g(x)$

$(-14,12)$ $\to$ $y =f(x)$ means:

$12 = f(-14)$

$f(-14)=12$

$g(x) = \frac{1}{3}f(x)$ is calculated

$g(-14) = \frac{1}{3} * f(-14)$

$g(-14) = \frac{1}{3} * 12$

$g(-14) = 4$

So, the corresponding point on $y = g(x)$ is: $(-14,4)$
