Answer:

The height is 0 when it "drops".

3/2x + 9 = 0

3/2x = -9

3 = -9(2x)

3 = -18x

3/-18x

Change signs, time cant be negative.

x= 6

Another interpretation; Slope is negative it is falling. This interpretation is more accurate.

-3/2x + 9 = 0

-3/2x = -9

-3 = -9(2x)

-3 = -18x

6 = x

The ice cream store sells sundaes. Each sundae costs $2.50 plus $0.35 for each topping. Find the rate of change and initial valu
Kobotan [32]

Answer:

rate of change: $0.35; initial value: $2.50; Equation: y= 0.35x + 2.50

Step-by-step explanation:

The rate of change is $0.35 because it's the one to change the total cost of the ice cream. If you get 3 toppings, you'll end up with 1.05 more dollars than if you had 0 toppings. And because of that, the initial value would also be $2.50, that's the minimum price you'll have to pay if you do want a sundae.

The equation is just restating all that, you start with the inital value b=$2.50, and the price will go up by 0.35 for every topping you add to the sundae.

Hope this helped :)

Factor the polynomial by grouping 7x2+16x-15
Alika [10]
16x can be broken down into factors of -105.
21 and -5 come to mind.

7x² + 21x - 5x - 15
7x(x + 3) - 5(x + 3)
(7x - 5)(x + 3) is the factorised form.

RUDIKE [14]

<u>Answer:</u>

\simeq 820 feet

<u>Step-by-step explanation:</u>

He has asked me to move the finish line 0.25 km forward

Now,

we know that

1 km = 0.621371 mile

⇒ 0.25 km = 0.25 \times 0.621371 mile  

                   = 0.25 \times 0.621371 \times 1760 \times 3 feet

(since 1760 yards = 1 mile and 3 feet = 1 yard)

                    = 820.20972 feet

                   \simeq 820 feet . (Answer)
