Y = mx + b, m is the slope and b is the vertical intercept. When given 2 points and the slope, enter the info into the equation, 3 = 2(1) + b and solve for b. 1×2=1. divide two from both sides cancelling out two and dividing 2 from 3. So then b = 3/2. Re-enter the info back into the equation. y = 2x + 3/2. Some assignments may ask you to put into a decimal. Otherwise keep it as a fraction

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the fut
lawyer [7]

Answer:

C=10000(0.852)^t

Step-by-step explanation:

Let the exponential function be,

C=a(b)^t

Here, C = cost of the car

t = Duration or period in years

From the given table,

Two points representing cost of the car and time are (10000, 0) and (8520, 1),

For (10000, 0),

10000=a(b)^0

a = 10000

For (8520, 1)

8520 = 10000(b)^1

b=\frac{8520}{10000}

b = 0.8520

Therefore, exponential equation will be,

C=10000(0.852)^t

jok3333 [9.3K]

Answer:

52 quarters, 42 dimes

Step-by-step explanation:

Let's call the number of quarters q, and the number of dimes d.

q+d=94

0.25q+0.1d=17.20

Subtract q from both sides of the first equation to isolate d:

d=94-q

0.25q+0.1(94-q)=17.20

0.25q+9.4-0.1q=17.20

0.15q=7.8

q=52

d=94-q=42

Hope this helps!
