Answer:
C. x = 5

Explanation:
Step 1 - Simplify the equation by adding the common terms

3x - 7 + 4x = 28
3x + 4x - 7 = 28
7x - 7 = 28

Step 2 - Add seven to both sides of the equation

7x - 7 = 28
7x - 7 + 7 = 28 + 7
7x = 35

Step 3 - Divide both sides of the equation by seven

7x = 35
7x/ 7 = 35/ 7
x = 5

Therefore, the correct answer should be ‘c. x = 5.’

Answer:

x = 5

Step-by-step explanation:

3x - 7 + 4x = 28

Combine like terms

7x -7 = 28

Add 7 to each side

7x - 7 +7  = 28+7

7x = 35

Divide each side by 7

7x/7 = 35/7

x = 5

Your client has saved $1,860 for a down payment on a house. A government loan program requires a down payment equal to 3% of the
Delicious77 [7]

If there is a $5,000 deposit, that means the amount to be mortgaged is $82,500. Calculating 3% of that amount:

0.03 * $82500 = $2475

The closing costs of the loan are $2,475. When they close the deal, they must bring that PLUS the down payment to the table, or $7,475.

(B)

If they are putting 30% down:

0.30 * $310000 = $93000

Add that to all of the other costs listed, they'll need to bring $94,165.

(C)

Discarding the $25,000, the Paltrows are asking for a $100,000 mortgage loan. 2% of that is $2,000, and so the total mortgage is for $102,000.

(D)

I can't answer this because I don't know how the interest is charged

Write the equation of the circle graphed below
Norma-Jean [14]

Answer:

The equation of the circle is

(x + 2)² + (y + 2)² = 9

Centered at (-2, -2), with radius of 3 units.

Step-by-step explanation:

The general equation of a circle is given as

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle, and r is the radius.

Looking at the graph, the center is the red dot. It corresponds to -2 on the y-axis, and -2 on the x-axis. So, the center (h, k) is (-2, -2).

The radius is the distance from the center of the circle to the edge of the circle. The red dot is the edge of the circle, there are 3 lines that represent 3 units, so we have a radius of 3 units.

Using these in the general equation, we have

[x - (-2)]² + [y - (-2)]² = 3²

(x + 2)² + (y + 2)² = 9

And this is the equation.
