Answer:
d. - 15
Step-by-step explanation:
The equation for direct variation is
y = kx
We know y =3 when x = -9
3 = k(-9)
Divide by -9
3/-9 = -9k/-9
-1/3 = k
The equation is then
y = -1/3 x
We know y = 5
5 = -1/3 x
Multiply each side by -3
-3*5 = -3*-1/3x
-15 = x

Answer:
114ft
Step-by-step explanation:
3 times 3=9
9times 2=18
8 times 3=24
24 times 2=48
8 times 3 = 24
24 times 2 =48
48+48+18=114
Answer:
y = 3x - 1
The slope intercept is -1.
To find the slope, do the formula (y sub2 minus y sub1)/(x sub2 minus x sub1) then reduce.
(14 - (-10))(5 - (-3)) = 24/8
24/8 = 3
To factor by grouping, you group up the 1st 2 terms together and the last 2 terms together and then factor those pieces.
(x^3 + x^2) + (x + 1)
x^2(x + 1) + 1(x +1) - now factor out the (x + 1)
(x + 1)(x^2 + 1) - final answer
