Answer:
12
Step-by-step explanation:
Answer:
Add 22/63
Step-by-step explanation:
3/7 + n = 7/9
<u>Step 1: Subtract 3/7 from both sides</u>
3/7 + n - 3/7 = 7/9 - 3/7
n = 49/63 - 27/63
n = 22/63
Answer: Add 22/63
(2x+3y)+(7x-3y)
First, group like terms together, so (2x+7x) + (3y-3y). Then simplify within the parentheses. 2x+7x = 9x and 3y-3y = 0, so you have 9x, which cannot be simplified any further. The answer is 9x.
Answer:
The average rate of change is -2
Step-by-step explanation:
we know that
To find out the average rate of change, we divide the change in the output value by the change in the input value.
In a linear function the average rate of change is a constant and is equal to the slope of the function
The linear function in slope intercept form is equal to

where
m is the slope or unit rate of the linear function
b is the y-intercept or initial value of the linear function
In this problem we have

so

therefore
The average rate of change is -2
