The equation is y=5/2x - 15 or if solving for X is -6
Step-by-step explanation:
In terms of y=mx+b, we are to make the Y by itself.
Step 1. -2y = -5x +30
Make y become positive!
Step 2. 2y = 5x - 30
Distribut the 2 over to make it 1y.
Step 3. 1y = 5/2x - 15
The equation is y=5/2x - 15
If you are to find X it would be....

Answer:

I would have to go with x = 8 and y = 5, meaning the solution is (8, 5).

Step-by-step explanation:

5x - 2y = 30

5(8) - 2(5) = 30

40 - 10 = 30

30 = 30

PLEASE HELP! SO CONFUSED! 25 POINTS!!
MrRa [10]

Answer:

D

Step-by-step explanation:

(f • g)(x)

= f(x) × g(x)

= (x + 4)(3x² - 7)

each term in the second factor is multiplied by each term in the first factor , that is

x(3x² - 7) + 4(3x² - 7) ← distribute both parenthesis

= 3x³ - 7x + 12x² - 28

= 3x³ + 12x² - 7x - 28 ← in standard form

I want to put $580 until I saving account for one year. The rate of interest On the account was 6 1/2%. How much was the interes
Vanyuwa [196]

Answer:

The amount of interest earned for the year is $37.7

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents principal or amount invested.

T represents the time

R represents the interest rate

I represents the interest

From the information given,

You want to put $580 into a saving account for 1 year. This means that

P = $580 and

T = 1 year

R = 6 1/2 = 6.5%

I = (580× 6.5×1)/100 = $37.7
