Answer:
C is the answer.
Step-by-step explanation:
What you do is you plug the numbers in to the equation according to the x and y.
So we will solve for y.
(3, 6) and (1, -2) is what you will be using. The 3 and 1 are the x and the 6 and -2 are the y.
So lets look at number C. y-2=4(x+1). You will add an x number into the x like this. y-2=4(3+1). You will then do the distributive property to get y-2=12+4.
You will then add 12 and 4 together to get y-2=16. You will then take the 2 and add it to the 16. to get y=18.
See how that doesn't equal 6 or -2 because those are y's. So C is the answer.
Answer:
1. 0
4. 6
Step-by-step explanation:
1. 2 x -1 + 1 ×2 = -2 + 2 = 0
2. 2x - 4 x 3 = 0
or 2x - 12 = 0
or 2x = 12
or x = 6
Answer:
Step-by-step explanation:
I don't see the choices, but I will make the equations that seems to be correct to me.
Known facts:
- maintained an average speed of 35 miles per hour (mph) for the first m hours of her road trip.
- next n hours of the trip, she drove at an average speed of 60 mph.
- Eva drove a total of 225 miles in 4.5 hours.
Let's make the equations:
m + n = 4.5
35m + 60n = 225
Hope that helps!
