What is the slope of 4Y + 8X + 2 = 0?

Answers

Answer 1

Answer: 4y+8x+2=0
-4y. -4y

8x+2=-4y

Divide by -4 on both sides

-2x-2/4= y

Y= -2x-2/4

The slope is -2

Jason ran 325 meters farther than Kim.Kim ran 4.2 kilometers.How many meters did Jason run?Estimate to check your answer

Answers

Convert km to m
4.2km = 4.2 x 1000 = 4200m

Jason ran 325m farther than Kim
⇒ 4200 + 325 = 4525m

Answer: Jason ran 4525m

4.2 km=4.2*1000=4200 m Kim ran
Jason 4200+325=4525 m Jason ran

Describe the translation. y=(x+3)2+4 → y=(x+1)2+6

Answers

Answer:

Shift +2 units to the right and +2 units up

Step-by-step explanation:

y = (x+3)² + 4 has a horizontal shift of -3 and a vertical shift of +4.

y = (x+1)² + 6 has a horizontal shift of -1 and a vertical shift of +6.

So do translate the first equation to the second, shift +2 units to the right and +2 units up.

Given the following system of equations: 2x + 6y = 12 4x + 3y = 15 Which action creates an equivalent system that will eliminate one variable when they are combined? Multiply the second equation by −2 to get −8x − 6y = −30. Multiply the first equation by 2 to get 4x + 12y = 24. Multiply the second equation by −4 to get −16x − 12y = −60. Multiply the first equation by −4 to get −8x − 24y = −48.

Answers

Answer:

Multiply the second equation by −2 to get −8x − 6y = −30.

Step-by-step explanation:

we have

----> first equation

----> second equation

Solve by elimination

Multiply the second equation by -2 both sides

---> equivalent second equation

Adds first equation and the equivalent second equation
