Answer:
x = -2 ± 452i
Step-by-step explanation:
x² + 4x = 117
x² + 4x - 117 = 0
if you solve this quadratic by using the quadratic formula you get:
x = -2 ± 452i
452i is an imaginary number that equals 
Answer:
Suzie's speed was 3.6 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed in mph (miles per hour)
x ----> the distance in miles
y ----> the time in hours
so
Find Suzie's speed
we have
substitute
Convert mixed number to an improper fraction
substitute
Answer:
113.04 (i used 3.14 for pi)
Step-by-step explanation:
area of circle formula = pi r^2
radius = 6
6^2 = 36
3.14 x 36 = 113.04
Answer:
area of the circle,
radius=10m
diameter=20m
πr²
3.14×100
314m²
area of the triangle=1/2×20×10
=100
area of the shaded area=314-100=214 m²
the answer is option <em>H</em>
Answer:
(0, -9) (1, -5)
Step-by-step explanation:
We know from the equation y = 4x -9, that the slope of the line is 4, and the point that the line crosses the y-intercept is at -9. So, your first point would be at (0, -9) and if you go one value over on the x-coordinate, that means the y-coordinate will go 4 up. So your final point will be (1, -5). The point could also be (2, -1), (3, 3), (4, 7), (5, 11), etc.
I Hope That This Helps! :)
