Answer:
y = 2x + 7
Step-by-step explanation:
y = mx + b The point (-2,3) gives us an x value and a y value that we can use. We are also give the slope (m). All we need to do is figure out the b (y-intercept) value.
y = mx + b
3 = 2(-2) + b
3 = -4 + b Add for to both sides
7 = b We know have every thing that we need to write the equation. We have the slope (m) which is 2 and the b (y-intercept) that we just figured out is 7
y = 2x + 7
Answer:
4
Step-by-step explanation:
because you subtract it.
When adding two digit numbers u will be looking at the ones and deciding if they can regroup them for a ten. You might want to equate regrouping with trading a term that you will understand immediately you will begin to add 2 digit numbers by using ten and ones blocks. And the answer is (107)
The length of the ramp is unknown.
If 6 ramps were cut from a board that is 12 1/2 feet long, the ramps would be about 2 feet long each which seems like a reasonable answer. The questions regarding how many boards are cut would need the length of the ramps. Lets say that the length is x. You can get 12 1/2 divided by x boards. In order to find out how much is left over, take the number of boards made, multiply it by how long they are. This product is then subracted from 12 1/2.
