Answer: In first question answer is -28x+4

In second question required inequality is 3x+100 < 2x-250

Step-by-step explanation:

1. Since, here the given expression is 4(x+5)-8(2+4x)

= 4x+20-16-32x ( By distributive property)

=-28x +4 ( By operating like terms)

2. Here, let the number is x.

Then according to the given question, three times the number of candy is increased by 100

That is, 3x+100

And, 250 less than the two times of the candy

That is, 2x-250

And, 3x+100>2x-250

Which is the required expression.

Hence she should subtract 250 from 2x not 2x from 250.

The graph of a function f is shown. Use the graph to estimate the average rate of change from x=-2 to x=0

Llana [10]

Answer:

Step-by-step explanation:

Given:

The interval, x = -2 to x = 0.

Required:

Average rate of change from x = -2 to x = 0.

SOLUTION:

From the graph,

If x = -2, f(-2) = 0.

If x = 0, f(0) = 4

Average rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

$a = -2, f(a) = 0$

$b = 0, f(b) = 4$

Plug in the values into the formula:

$= \frac{4 - 0}{0 -(-2)}$

$= \frac{4}{2} = 2$

Average rate of change from x = -2 to x = 0 is 2.

What numbers are a distance of 23 unit from 12 on a number line?

Svetach [21]

You can solve this by using the expressions 12+23 and 12-23.

12+23=35

12-23=-11

35 and -11 are 23 units away from 12 on a number line.

How do you find the percent change?

antoniya [11.8K]

Hello!!
To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.
let me know if u have anymore questions!:)
