Answer:
B) r= c/2
Step-by-step explanation:
To isolate r, divide 2 on both sides
c = 2r
-- --
2 2
c/2=r

Answer:
see below
Step-by-step explanation:
y=x^2-4x-12
Set equal to 0 to find the zeros
0 =x^2-4x-12
Factor. What 2 numbers multiply to -12 and add to -4
-6*2 = -12
-6+2 = -4
0= (x-6) (x+2)
Using the zero product property
0=x-6 0 = x+2
x=6 x = -2
zeros: -2,6
Vertex
h = -b/2a = - (-4)/ 2(1) = 4/2 = 2
OR Average the roots (-2+6)/2 = 4/2 =2
The y coordinate is found by substituting into the equation
y = (2)^2 -4(2) -12
y = 4-8-12
y =-16
vertex : (2, -16)
Answer:
<u>Use 2 points from he table to find the slope of f(x):</u>
<u>The slope is:</u>
The y - intercept is b = -1 according to point (0, -1).
<h3>Part A</h3>
<u>The lines are:</u>
- f(x) = 8x - 1
- g(x) = 3x - 2
The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.
<h3>Part B</h3>
See above
