Answer:

The only thing I can think of is -2.

Step-by-step explanation:

-9 + 7 = -2

I'm not sure if you wrote the questions or the answers wrong, but if I'm reading it right the answer should be -2, not 2. Unless you meant to write 9 + -7, in which case the answer would be 2.

Determine the intercepts of the line. y=4x+7

luda_lava [24]

To get your answer we'll plug 0 in for x into the equation.

So, multiply 4*0 which equals 0.

$y=0+7$

Then we'll add 0 and 7 which leaves us with

$y=7$

The y-intercept of this equation is: $(0,7)$

To find the x-intercept of this equation we'll rewrite it as $4x+7=0$

Then we'll subtract 7 from both sides,

$4x=-7$

Now we'll divide each side by 4. Then simplify which brings us to our answer,

$x= -\frac{7}{4}$

The x-intercept of this equation is: $( -\frac{7}{4} ,0)$

I hope I helped you! If you need any more help let me know!

Sum-R-Fun sells a jet ski for $6,700 which includes tax. They offer an installment plan that requires 20% down. After that, the

nlexa [21]

Answer:

1) The initial down payment is $1,340

2) The total monthly payment is $7,200

3) The total cost of the jet ski on the installment plan is $8,540

4) The finance charge is $1,840

Step-by-step explanation:

The financing model of Sum-R-Fun for a jet ski are as follows;

Sum-R-Fun selling price of a jet ski = $6,700

The initial down payment = 20% of the selling price of the jet ski

The amount the customer pays per month = $200

The duration or the period of the monthly payment = 3 years

1) The initial down payment = 20/100 × $6,700 = $1,340

2) The total monthly payment = Number of months per year × Number of years × The monthly (installment) payment

∴ The total monthly payment = 12 × 3 × $200 = $7,200

3) The total cost of the jet ski on the installment plan = The initial down payment + The total monthly payment

∴ The total cost of the jet ski on the installment plan = $1,340 + $7,200 = $8,540

4) The finance charge is the cost of the credit given as follows;

The finance charge = The total cost of the jet ski on the installment plan - Sum-R-Fun selling price of a jet ski

∴ The finance charge = $8,540 - $6,700 = $1,840
