brilliants [131]3 years ago
4 0

Answer:

x^2 – 4 = 0

Step-by-step explanation:

When x = - 2,

x^2 - 4 = 0

( - 2 )^2 - 4 = 0

4 - 4 = 0

When x = 2,

x^2 - 4 = 0

2^2 - 4 = 0

4 - 4 = 0

24 divide by blank plus 5 multipled by 3 plus 2 equals 20
sineoko [7]

Answer:

8

Step-by-step explanation:

The answer would be 8 because the question would be

24 ÷ x + 5 × 3 + 2=20  right?

The first thing you would want to do is multiply the 5 and the 3 because of PEMDAS which should give you  24 ÷ x + 15 + 2 = 20.

15 plus 2 is 17 and then you would subtract 17 from 20 which would give you 3. So you know know that 24÷x has to be 3 and 24÷3 is 8 so x=8.

Hope this helped!

Find the rate of change
Tatiana [17]
\bf slope = m = \cfrac{rise}{run} \implies 
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby 
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\
h(x)= 2^x  \qquad 
\stackrel{2\le x\le 4}{\begin{cases}
x_1=2\\
x_2=4
\end{cases}}\implies \cfrac{h(4)-h(2)}{4-2}\implies \cfrac{2^4-2^2}{2}
\\\\\\
\cfrac{16-4}{2}\implies \cfrac{12}{2}\implies 6
