Answer:
<h2>f(-2) = 13</h2>
Step-by-step explanation:
f(x) = x² - 2x + 5
Yo find f(-2) substitute the value of x that's - 2 into f(x) that is for every x in f (x) replace it with - 2
So we have
f( - 2) = (-2)² - 2(-2) + 5
= 4 + 4 + 5
= 8 + 5
We have the final answer as
<h3>f(-2) = 13</h3>
Hope this helps you
Answer:
A=E
B=F
C=G
D=H
Step-by-step explanation:
The equation you write would be linear, and would be written in slope intercept form y=mx+b. Since Mr. Miller already has $25, we plug that in for "b" in the equation. We plug 10 in for "m", because "x" represents the number of weeks he has been saving. The equation would be y=10x+25. To find how much money Mr. Miller will have in 7 weeks, plug in 7 for x. y=10(7)+25 -> y=70+25 -> y=95 -> $95
Step-by-step explanation:
(3x-15)°= 105°
3x=120
x=40°
(y+25)°=180-105
(y+25)°=75°
y=75-25
y=50°
