Answer:

Step-by-step explanation:

The angles are complimentary, so they add to 90

6x + 3 + 7x + 9 = 90             Combine like terms

13x + 12 = 90                         Subtract 12 from both sides

13x = 90 - 12                          Combine

13x = 78                                 Divide both sides by 13

x = 6

<A = 6x + 3

<A = 6*6 + 3

<A = 36 + 3

<A = 39

Mitchell has $17000 to put towards a car. He wants to invest this money in an account paying 3.3%/a
arsen [322]

Answer:

He can afford the monthly payment of the Ford car since his accumulated interest after 5 years is greater than the amount the Ford will cost

Step-by-step explanation:

For the Ford

There are 60 months in 5 years so the total amount he will be paying is 60 * 299 = $17,940

For the Volkswagen, amount to pay will be 60 * 389 = $23,340

Now to see the payment he can afford, let’s calculate the amount he will have in his savings

We shall use the formula for compound interest here

A = I(1 + r/n)^nt

where A is the amount after the

number of years

I is the initial amount = 17,000

r is the rate = 3.3% = 3.3/100 = 0.033

n is the

number of times interest is compounded per year = 12

t = number of years = 5

plugging these values we have

A = 17,000(1 + 0.033/12)^12(5)

A = 17,000( 1.00275)^60

A = $20,045

This shows he can afford the Ford

PLEASE HELP ME 10 Points
ra1l [238]

Answer:

y = 1/2 x + -5

Step-by-step explanation:

Slope-intercept form is y = mx + b

where m is the slope and b is the y-intercept

m is equal to change in y/ change in x ( aka horizontal change over vertical change), in the graph the horizontal change is 1 up for every 2 units right, which equals 1/2

b is the y-intercept (when x=0), if you look at the graph x=0 when y=-5

Lastly, you put in m and b into the equation to get y = 1/2 x + -5
