(-5a)(-3a ²)
=
15a³

-5 x -3 = 15 ( negative times negative = positive)
a x a² = a³ ( when multiplying exponents, you add the exponents together )

Which equation has the solution of (3, 0) and an undefined slope y=4 x=3 y=4x y=4x+3

Liula [17]

The answer is x = 3, because x = 3 has an undefined slope (m = 0 or is imaginary), and it contains 3, 0 which makes 3, 0 a solution.

3/4 −(x+ 1 /8 )= 5/16

IRINA_888 [86]

3/4-(x+1/8)=5/16

3/4-x-1/8=5/16

3/4-1/8-5/16=x

Common denominator: 16

x=(4×3-2×1-5)/16=(12-2-5)/16=5/16

Answer: x=5/16

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its r

frosja888 [35]

You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds
