Step-by-step explanation:

An = -2 * An-1

What this means is that you multiply -2 to the term to get the next term.

Since our 1st term (A1) is -2, we have:

A2 = -2 * A1 = -2 * (-2) = 4,

A3 = -2 * A2 = -2 * (4) = -8,

A4 = -2 * A3 = -2 * (-8) = 16,

A5 = -2 * A4 = -2 * (16) = -32,

A6 = -2 * A5 = -2 * (-32) = 64.

Hence our first 6 terms in the GP are

-2, 4, -8, 16, -32 and 64.

If f(x) = х2 – 2x and g(x) = 6х +4, for which vаluе оf x does (f + g)(x) = 0?
zhannawk [14.2K]

Answer:

x = - 2

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4

Equating to zero, that is

x² + 4x + 4 = 0 ← left side is a perfect square

(x + 2)² = 0, thus

x + 2 = 0 ⇒ x = - 2

Find y if the line through (3, 1) and (9, y) has a slope of 4.
klio [65]

Answer:

y = 25

Step-by-step explanation:

To find slope, we use this expression: \frac{y2-y1}{x2-x1}

Since we already know the slope and are trying to figure out a y-value, we can input all of the values we do know in the expression and solve for the missing y.

\frac{y-1}{9-3}=4

Simplify the denominator:  \frac{y-1}{6}=4

Multiply both sides by 6 to isolate the y - 1:   y - 1 = 24

Add 1 to both sides to isolate the y:  y = 25

y = 25
