Answer:

Their slope is the same. Perpendicular

Step-by-step explanation:

3x + 4y = 12

4y=12-3x

y=-3/4x+3

6x + 8y = 48

8y=48-6x

y=-3/4+6

Without multiplying, tell which is greater: 4/5 x 45 or 2/3 x 45. Explain.
Aloiza [94]

Answer: It is 4/5 x 45

Step-by-step explanation: Hope i helped please mark brainliest!

I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30

therefore, 4/5 x 45 is greater!

also, if not multiplying 0.8(5/4) is greater than 0.667(2/3). Therefore, 4/5 is greater than 2/3.

An employees hourly raise went up from $10 per hour to $12 per hour. What is the rate of increase?
Anastaziya [24]

20% because:

rate of Increase = ( final - initial ) / initial * 100

rate of increase = ( 12 - 10 ) / 10 * 100

rate of Increase = 2 / 10 * 100

rate of Increase = 20

What are the x and y-intercepts of the line?
natta225 [31]

Answer:

B

Step-by-step explanation:

To find the y-intercept, plug in x=0 in the original equation. (You want to find what y is when x=0)

2x + 3y = -12

2(0) + 3y = -12 (Plug in x=0)

3y = -12 (2*0=0, so you can ignore that part)

y = -4 (Divide both sides by 3)

This narrows down our choices to either A or B.


To find the x-intercept, plug in y=0 into the original equation. (You want to find what x is when y=0)

2x + 3y = -12

2x + 3(0) = -12 (Plug in y=0)

2x = -12 (3*0=0, so you can ignore that part)

x = -6 (Divide both sides by 2)


If our x intercept is -6 and our y intercept is -4, that makes our answer B.
