( 1 ) First graph -

x-intercept = 2

y-intercept = -4

y=2x-4

[ Proof ]

2x-4=0\\2x=4\\x=2

For y-intercept, it's y = 0 -4 = -4

( 2 ) Second graph -

x-intercept = 2

y-intercept = 1

slope = -1/2

y=-\frac{1}{2}x+1

[ Proof ]

-\frac{1}{2}x+1=0\\-x+2=0\\-x=-2\\x=2

For y-intercept, it's y = 0 + 1 = 1

So it's y = 2x - 4

and y = -1/2x + 1

Answer:

  a) $15,779.70

  b) $13,679.70

  c) $210.92

Step-by-step explanation:

a) When tax is added, the total cost is ...

  total = price × (1 +tax rate)

  total = $14,775 × 1.068 = $15,779.70

__

b) The amount financed is the difference between the total cost and the down payment.

  financed = total - down35

  financed = $15,779.70 -2100 = $13,679.70

__

c) The monthly payment is found using the amortization formula. It can also be found using any of a number of financial calculators, spreadsheets, or apps.

  A = P(r/12)/(1 -(1 +r/12)^-n) . . . . annual rate r, n monthly payments, principal P

  A = $13,679.70(0.035/12)/(1 -(1 +0.035/12)^-72) ≈ $210.92

Solve for x<br> 3.24x + 8.37x -8.09=7.83<br> X= <br> Round your answer to the nearest hundredth
amm1812

3.24x + 8.37x -8.09=7.83

adding 3.24 x and 8.37x on the right side:

3.24x + 8.37x -8.09=7.83

11.61x -8.09=7.83

adding 8.09 to both sides:

11.61x =7.83+8.09

11.61x =7.83+8.09

11.61x =15.92

dividing both sides by 11.61
