A. False. The domain (x-coordinates) starts at 0, not at 100.

b. True. The range (y-coordinates) does start at 100 and increases.

c. True. The graph moves up to the right showing an increase in y as x increases.

d. True. Point (40, 222.11) means that when x = 40 years, y = $222.11.

e. False. The initial point is at x = 0 when the account was opened. At x = 1, it is already 1 year after the account was opened.

Order the steps to solve the equation log(x^2-15)=log(2x) form 1 to 5

nasty-shy [4]

Answer:x=-5 and x=3

Step-by-step explanation:

log(x^2-15)=log(2x)

Cancel log at both sides we get

x^2-15=2x

Collect like terms

x^2-2x-15=0

x^2-3x+5x-15=0

x(x-3)+5(x-3)=0

(x+5)(x-3)=0

x+5=0 x-3=0

x=-5 x=3

2. Pam is making fruit baskets. She has 30 apples and 24 bananas.

Digiron [165]

Answer:

Six

Step-by-step explanation:

$\dfrac{\text{apples}}{\text{bananas}} =\dfrac{30}{24}$

Find the greatest common factor of each number.

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

The greatest common factor of 30 and 24 is 6.

Jane can make six fruit baskets if she divides the fruit evenly among them.

Harlamova29_29 [7]

Answer:

9/20

Step-by-step explanation:

You set the fraction up at first as 45/100. Then you know that 5 goes into each so you divide by 5 $\frac{45}{100} /5$

45/5=9

100/5=20

You get 9/20, and this is in simplest form.
