Slope = Y2 - Y1 / X2 - X1
Slope =(3-5) / (-3-[-3])
Slope = -2 / 0
The answer is infinity because anything divided by 0 = infinity.
15% would be 8.4585
hope this helps!!
Answer:
x = -2 ±sqrt( 19)
Step-by-step explanation:
x^2 + 4x = 15
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 = 4
Add it to each side
x^2 + 4x+4 = 15+4
(x+2)^2 = 19
Take the square root of each side
sqrt( (x+2)^2) =±sqrt( 19)
x+2 = ±sqrt( 19)
Subtract 2 from each side
x+2-2 = -2 ±sqrt( 19)
x = -2 ±sqrt( 19)
Answer:
D
Step-by-step explanation:
D is not a function because x's repeat. Each x value should have its own unique y value. The graph also fails the vertical line test, meaning that if you were to draw a vertical line anywhere on the graph it would intersect with more than one point.
