Remark

What you are trying to do is isolate the y value. Then you just interpret what you found.

Equation

-9x + 10y = - 9

Solve

x and y must be on opposite sides of the equal sign. Add 9x to both sides.

10y =  9x - 9                  Divide by 10

y = 9x/10 - 9/10

There's the equation. Now all you need do is interpret it.

Meaning

The general equation for this situation is

y = mx + b

m (the number in front of the x) is the slope

y = 9/10 x - 9/10

So the slope is 9/10

b  is the number by itself on the right. It is the y-intercept and it it -9/10

Since slope is greater than 0, C cannot be right.

Since the y intercept is less than 0, A, B, and C are all incorrect which leaves D

Answer D

Equation:

-9x+10y=-9

10y=9x-9

y=9/10x-9/10


Slope: 9/10

Y intercept:  -9/10


So your answer is D

Find the area of the shaded region in square units. Show your reasoning.
motikmotik

Answer:

40 square units

Step-by-step explanation:

First of all, lets say that square has side l, so, the area unit is l^2

the diagonal's square is l\sqrt{2}

CALCULATION OF TRIANGLES'S AREA (there are 4 triangles)

A_{triangles}=4*base*heigh*0.5=2*(l\sqrt{2} )(2l\sqrt{2} )=8l^2

CALCULATION OF MAIN SQUARE AREA

A_{square}=side*side=(4\sqrt{2} l)(4\sqrt{2} l)=32l^2

TOTAL AREA

A_{total}=A_{triangles}+A_{square}=8l^2+32l^2=40l^2

Can someone help me please?

(6x + 30)+(2x+6)= 180
8x +36= 180
8x= 144
X= 18
So 2x+6 = 42
And 6x+30 = 138

The full workings for the house purchase you made on a mortgage are as follows:

1. Price of House = $499,000 (given)

2. Down Payment = $99,800 ($499,000 x 20%)

3. Amount Financed (Mortgage principal) = $399,200 ($499,000 - $99,800).

4. Monthly Payment = $2,522.94 (given)

5. Number of monthly payments = 360 months (30 x 12)

6. Total Payback = $908,258.40 ($2,522.94 x 360)

7. Total Interest = $509,058.40 ($908,258.40 - $399,200)

8. Assessed Valuation = $199,600 ($499,000 x 40%)

9. Real Estate Taxes (annual) = $6,047.88 ($199,600 x $3.03/$100)

10. Escrow Payment Per month (taxes & insurance) = $628.99 ($6,047.88 + $1,500)/12

11. Monthly Payment to lender (escrow + mortgage) = $3,151.93 ($628.99 + $2,522.94)

<h3>What is a mortgage?</h3>

A mortgage is a loan arrangement that allows a borrower to buy some property, usually a house, without paying for the full cost immediately.

The borrower then makes a monthly payment, which includes the principal and its interest.
