What are these two equations in slope intercept form?

Answers

1. 4x - y = 8
4x = y + 8
Y = 4x - 8

2. 2x + 3y = 4
3y = -2x + 4
Y = -2/3x + 4/3

Answer:

4x - y = 8

4x = y + 8

Y = 4x - 8  

2x + 3y = 4

3y = -2x + 4

3(x-4)=5(x+2)

Answers

Answer:

x = -11

Step-by-step explanation:

1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis

3x-12 = 5x + 10

2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)

2x = -22

3. Divide both sides by 2

x = -11

please give me brainliest if this helped

Answer:

x=−11

Step-by-step explanation:

3(x-4)=5(x+2)

Simplify both sides of the equation:

3(x−4)=5(x+2)

(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)

3x−12=5x+10

Subtract 5x from both sides

−2x−12=10

add 12 to both sides

−2x=22

Divide by -2 both sides

x=−11

Find the sales price for a $900 TV with a 25% discount.
Discount = Regular Price X Rate of Discount Sales Price= Regular Price - Discount.
b. Discount (mark down Expression) = ((Original price – (Original price x discount rate))

Answers

Answer:

$675

Step-by-step explanation:

100%=>$900

25%=>X

25% × $900 ÷ 100% = $225

So $900 - $225 = $675

AWNSER

$ 675 with discount

EXPLANATION

If it is 25% off of the sales price we can infer that you are paying 75% of the sales cost.

To find the price you answer the equation

900•.75= 675

Therefore the total cost with the discount of 675 dollars.

C The number that is 2 to the left of -5 on the number line
D The number that is 2 to the right of -5 on the number line

Answers

Answer:

B

Step-by-step explanation:

when rewriting it, it would be 2+5 because subtracting a negative number is the  same as adding.

so it would be 5 to the right(since you are increasing/adding) to 2 (the beginning/starting point)
