Answer:
D)
Step-by-step explanation:
f(x) = x^2 -14x -72
0=x^2 - 14x-72
0=x^2 - 18x+4x-72
0=x(x-18)+4(x-18)
0=(x-18)(x+4)
x-18=0 or x+4=0
x1=18 or x2=-4
asis of symmetry: x=(x1+x2)/2
x=(18+(-4))/2
x=14/2
x=7
Answer:
y = 2x + 4
Step-by-step explanation:
First find 2 points on the line to determine slope.
(0, 4) and (2, 8)
Slope =
y = 2x + b
b = y - intercept
b = 4
y = 2x + 4
Answer:
The exact distance between the two points is 10
Step-by-step explanation:
Tyler finished more of the art project.
Carlos finished 1/3
In terms of percentage 1/3 *100% = 33.3%
Tyler finished 1/2
In terms of percentage 1/2 *100% = 50%
50% > 33.3%
50% is greater than 33.3%
the answer is A. hope this helps
