Answer:
174.25
Step-by-step explanation:
To solve this equation I will assume you are 15 as this is a High School level problem.
1. Plug in 15 for x
-.85*15+187
2. Solve
-.85*15=-12.75
-12.75+187=174.25
The answer should be the directrix because k represents the y-value of the vertex, and for this questions the parabola is probably facing upward, so the directrix is under the vertex.
Answer:
Using a calculator, if you typed in 9 divided by 2, you'd get 4.5. You could also express 9/2 as a mixed fraction: 4 1/2.
Answer:
y = 4x -14
Step-by-step explanation:
The required answer form is slope-intercept form, so we need the slope and the y-intercept of the line.
The slope equation is ...
m = (y2 -y1)/(x2 -x1)
m = (10 -2)/(6 -4) = 8/2 = 4
The y-intercept equation is ...
b = y - mx
b = 2 -4(4) = -14
The equation of the line is y = 4x -14.
