Answer:

28*4/7

Step-by-step explanation:

4/7

   the 7 represents the 28.  28 is a multiple of 7.

<u>28</u>  *   <u>4</u>   =     <u>112</u>   =   16

 1        7           7

<u><em>there are 16 girls</em></u>

also we know 4*7=28 so if we count the multiples of 4, there is 4 8 12 and the 4th multiple is 16.

Why is 3 to the power 0 = 1
Nostrana [21]
When we raise something to a power, it really justs means we are multiplying it by itself. 3^2 (3 to the power of 2) means that we are mutliplying 3 by itself: 3•3 = 9 or 3^2 = 9 (there are two 3's) 

However, when we rasie something to the 0 power, it equals 1. That is because we are multiplying it by itself 0 times. We are not multiplying it by zero, we are effectively doing nothing at all. 3^0 = 1

What is the average rate of change for the function f(x)=3x^2 -5 on the interval −3 ≤ x ≤ −1 ?
Anestetic [448]

Answer:

-12

Step-by-step explanation:

Let b = -1 and a = -3

The average rate of change = \frac{f(b) - f(a)}{b - a}

f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2

f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22

f(b) - f(a) = -2 - 22 = -24

b - a = -1 + 3 = 2

\frac{f(b) - f(a)}{b - a} = -24/2 = -12

Which property is illustrated by the following statement? If ZXY= FDE, and FDE= CAB, then ZXY=CAB
blagie [28]

Answer:

Transitive property of equality

Step-by-step explanation:

By the definition of transitivity, a relation R is said to be transitive if (a, b) ∈ R and (b, c) ∈ R, then (a, c) ∈ R.

If p = q, q = r then p = r.

Here, we have given that if ZXY = FDE and FDE = CAB, then, ZXY = CAB.

Therefore, it shows the transitive property of equality.

Write an equation for the translation of y = |x|. 13 units down
olga55 [171]
The idea for transitions for an equation like this is
y = m|x - h| + k
where m = slope
h = how much left or right (note the negative)
k = how much up or down

moving 13 down would mean
k = -13

so
y = |x| - 13
