X=2
y=3

Insert 2 geometric means between -32 and 4
denis23 [38]

Answer:

16, -8

Step-by-step explanation:

Let the terms of the geometric sequence be a, ar, ar^2, ar^3.

We know that a=-32 and thus, -32r^3=4 \implies r=-1/2.

This means ar=(-32)(-1/2)=16 and ar^2=-32(1/2)^2=-8.

Which equation represents h(x)?
Lelechka [254]

Answer: The second choice: h(x) = (f(x))(g(x))

Step-by-step explanation:

f(x) = -15

g(x) = 15

h(x) = -225

-15 * 15 = -225

Therefore, h(x) is the distribution of f(x) and g(x).

Help I don't understand how to do this
klasskru [66]

Answer:

Step-by-step explanation:

Given

Points (-1,7) and (1,3)

Formula

m = (y2 = y1) / (x2 - x1)

y2 = 7

y1 = 3

x2 = - 1

x1 = 1

Solution

m = (7 - 3) / (-1 - 1)

m = 4 / - 2

m = - 2

Now use either one of the points to get b in y = mx + b

x = 1

y = 3

m = - 2

y = mx + b

3 = -2 (1) + b

3 = -2 + b

b = 3 + 2

b = 5

Equation: y = - 2x + 5

Second question.

y = -2 + 1  

Think money. You have a dollar in your pocket, but you owe your mom 2 dollars. Where are you.

y = -2 + 1

y = - 1
