Substitute x for 7.
f(x)=22x+12
f(7)=22(7)+12
Multiply first, then complete addition.
f(7)=154+12
f(7)=166
Answer:
176.8
Step-by-step explanation: first you have to find the radius by finding the half of 15 which is calculated to be 7.5
and the formula to find the area is A=
1/3, 0,1,-2.....neither geometric or arithmetic
Answer:
So there are infinite solutions along the line y = 2x-1
Step-by-step explanation:
10x=5y+5
y=2x-1
Substitute y into the first equation
10x = 5(2x-1) +5
10x = 10x-5+5
10x = 10x
This is always true
So there are infinite solutions along the line y = 2x-1
Yep it’s B or 20 outcomes
