Replacing for values of a and c in the equation
a=20
c=8
m=4a+2c
m=4(20)+2(8)
m=80+16
m=96
(-6,0)
Intersecting at x-axis means that the point at which it will intersect will have a x coordinate but no y coordinate.
So,In the equation,y=-3x-18
put y=0
-3x-18=0
or,3x=-18
or,x=-6
So,the point of intersection is (-6,0)
F(5) = 2(5)^2 - 10
f(5) = 2(25) - 10
f(5) = 50 - 10
f(5) = 40
The average is the sum of the numbers divided by the quantity of numbers.
-100 + 102 =2
2/2 = 1
The average is 1
Step-by-step explanation:
I think c is right answer
