The line crosses (1/2,0) and (0,4/7)

Let m be the slope of this line

● m = [0-(4/7)]/[(1/2)-0)]

● m = (-4/7)/(1/2)

● m = (-4×2)/7

● m = -8/7

So the slope of this line is -8/7

Mark buys Apple stock for $100 and its value increases by a factor of 1.5 each week. Which equation represents the relationship
Bingel [31]

Given:

Initial value of the stock = $100

Growth factor = 1.5 each week.

To find:

The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.

Solution:

Let V be the current value of the stock after t week.

The exponential growth model is:

V=ab^t

Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.

Substituting a=100,b=1.5, we get

V=100(1.5)^t

Therefore, the required equation for the given situation is V=100(1.5)^t.

Evaluate the function g(x) = -2x- + 3x - 5 for the input values -2, 0, and 3.
gladu [14]

Answer:

g(-2)=3

g(0)=-5

g(3)=2

Step-by-step explanation:

g(-2)= -2(-2)+ 3(-2) - 5

4-6-5

2-5

g(-2)=3

g(0)= -2(0) + 3 (0)-5

0+0-5

g(0)=-5

g(3)= -2(3) + 3(3)-5

-6+9-5

3-5

g(3)=2

What two numbers add up to 18 and multiply to 80
mestny [16]

Answer:

8 and 10

Step-by-step explanation:

First, let's look at the factors of 80.

1 • 80 = 80

2 • 40 = 80

4 • 20 = 80

5 • 16 = 80

8 • 10 = 80

Look at each pair and evaluate their sum.

1 • 80 = 80

  • 1 + 80 = 81

2 • 40 = 80

  • 2 + 40 = 42

4 • 20 = 80

  • 4 + 20 = 24

5 • 16 = 80

  • 5 + 16 = 21

8 • 10 = 80

  • 8 + 10 = 18

Our last pairing multiplies to 80 and adds up to 18. Therefore, your answer is 8 & 10.

Hope this helps!
