Mathematics

nordsb [41]2 years ago
6 0

Answer:

9

Step-by-step explanation:

Let the unknown number be x

Sum means add

7 + 3x = 34

Subtract 7 from each side

7+3x-7 = 34-7

3x = 27

Divide by 3

3x/3 = 27/3

x = 9

Find the average rate of change for the given function from x = −2 to x = 1. Graph of f of x equals x minus 5
Nataliya [291]
Average rate of change=slope

f(x)=x-5
f(x) could be subsitututed  with y so
y=x-5
this is in y=mx+b form where m=slope and b=y-intercept
y=1x-5
slope=1
average rate of change=1/1
if x=-2 then
y=-2-5
y=-7

if x=1 then
y=1-5
y=-4


the graph of y=x-5 is included in the attachment
