ehidna [41]

the amount of time of the two trips is a proportional relationship

<h3>What is proportional relationship?</h3>

mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.

<u>solution:</u>

Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph

while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph

since both situations gave similar speed in miles per hour they are said to have a proportional relationship.

Solve for x<br><br><br> 6x−2(x+4)=12
aev [14]
To solve for x, we will begin by using the distributive property

6x - 2(x + 4) = 12

6x - 2x - 8 = 12

(always remember to sort your negatives!)

Add like terms 

4x - 8 = 12

Add 8 to both sides

4x = 20

Divide both sides by 4

x = 5

Victoria has $200 of her birthday gift money saved at home, and the amount is modeled by the function h(x) = 200. She reads abou
san4es73 [151]

Answer:

h(x) * s(x) = 200(1.05)^(x - 1)

Step-by-step explanation:

Our interest equation is s(x) = (1.05)^(x - 1). This is actually a part of a bigger formula for calculating the amount of money accumulated including interest:

A = P(1 + r)^n, where A is the total, P is the principal amount (initial amount), r is the interest rate, and n is the time

Here, we technically already have the (1 + r)^n part; it's just (1.05)^(x - 1). The principle, though, will actually be the 200 because she starts out at $200.

Thus, to combine these, we simply multiply them together to get:

h(x) * s(x) = 200(1.05)^(x - 1)
