Answer:

Step-by-step explanation:

We know:

The diagonals of the parallelogram are divided in half.

Therefore

EK ≅ KG and HK ≅ KF.

We have

EK = 7x + 5, KG = 3x + 17, HK = 3y - 11 and KF = y + 5

Equations:

(1) 7x + 5 = 3x + 17

(2) 3y - 11 = y + 5

Solutions:

(1)

7x + 5 = 3x + 17 subtract 5 from both sides

7x + 5 - 5 = 3x + 17 - 5

7x = 3x + 12 subtract 3x from both sides

7x - 3x = 3x - 3x + 12

4x = 12 divide both sides by 4

4x/4 = 12/4

x = 3

------------------------------

(2)

3y - 11 = y + 5 add 11 to both sides

3y - 11 + 11 = y + 5 + 11

3y = y + 16 subtract y from both sides

3y - y = y - y + 16

2y = 16 divide both sides by 2

2y/2 = 16/2

y = 8

Write equations for the horizontal and vertical lines passing through the point (-2,-5).

erastova [34]

Answer:

y = -5
x = - 2

=============================

The horizontal line has same y- coordinate for each x- coordinate, and is parallel to the x-axis so it is:

y = - 5

The vertical line has same x- coordinate for each y- coordinate, and is parallel to the y-axis so it is:

x = - 2

Ernie Rolph deposits $4500 at 2% annual simple interest for 1 year. How much interest will he earn?

vaieri [72.5K]

Answer: the amount of interest that he would earn is $90.

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount of money deposited.

P represents the principal or amount of money deposited.

R represents interest rate on the deposit.

T represents the duration of the deposit in years.

From the information given,

P = $4500

R = 2%

T = 1 year

Therefore,

I = (4500 × 2 × 1)/100

I = $90
