If i is a normal variable: then it is -30i^2 - i*j + 20j^2
If i is the constant i, then it is 20j^2 -i*j + 30
Answer:50
Step-by-step explanation:
Bc 25+25 is 50.
The answer would be 2
the hint to find out how would be <span>f(-2) is the y value of the point when x = -2</span>
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
