You’d have to try to get r on one side of the equation.
You can do that by subtracting 12 from both sides which would make it so
R = -9
Answer:
A
Step-by-step explanation:
Vertex appear to be at (5,115)
A) h = -b/2a
= -(20)/2(-2) = 5
k = -2(5²) + 20(5) + 60 = 110
Answer:
$
Step-by-step explanation:
divided by 
We round to nearest cent.
Answer:
y = 5x
Step-by-step explanation:
you can use the Slope-Intercept form of a line, which is:
y = mx + b where 'm' is the slope, and 'b' is the y-intercept
to find the slope, select any two points:
we can use (0,0) and (2,10)
now subtract the y-values and the x-values to get this fraction:
slope = 10-0 / 2-0
slope = 10/2 or 5/1
the y-intercept can be seen and is 0
therefore, equation of this line is:
y = 5x + 0 or
y = 5x
