Answer:

Step-by-step explanation:

If -30 is its only zero, than the factors are (x+30)(x+30) = $x^2 + 60x + 900$

Than b = 60

Two events, A and B, are independent of each other. P(A) = 1/6 and P(A and B) = 1/8 What is P(B) written as a decimal? Round to

Leona [35]

P(B) = 0.75.

For independent events, P(A and B) = P(A)*P(B). This gives us

1/8 = 1/6(x)

Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x

3(x+6)=2(4x+14)<br> what is the value of x?

GrogVix [38]

Hi there

3(x + 6) = 2(4x + 14)
3x + 18 = 8x + 28
3x - 8x = 28 - 18
-5x = 10
x= 10/-5
x = -2

Here it is :)

Is this linear, exponential, or quadratic?

Lady_Fox [76]

Linear. Each increase of 1 in x means a decrease of 3 in y, so it has a consistent slope of -3
