Answer:
C.
Step-by-step explanation:
x^2+20^2=25^2
x^2+400=625
x^2=225
x=15
Answer:
A is not a function
Step-by-step explanation:
In table A, the x value of 4 goes to two different y values
To be a function each x value can only go to one y value
A is not a function
Answer:
y=MX+b
Step-by-step explanation:
b is your y intercept
m is your slope
<span>Y=3x+2 slope = 3
</span><span>perpendicular, slope = -1/3
answer is C) </span><span>-1/3 </span>
<span> zeros of the quadratic function when f(x) = 0
so
</span><span>8x^2 – 16x – 15 = 0
(8x + 5)(x - 3) = 0
8x + 5 = 0; x = -5/8
x - 3 = 0; x = 3
Answer
x = -5/8 and x = 3</span>
