True. If you're just changing the form, yes. But remember when you change one side of an equation, you must change the other in the same way.
729. You just do 9 to the power of 3 or 9^3 and you will get 729. If it is not allowed, the answer is 504.(9 x 8 x 7)
the slope is -12 because y=mx+b and m= slope
Answer:
2,400h
Step-by-step explanation:
You multiply the amount of skiers per hour (2,400) by the amount of hours (h).
Answer:
Hi there the answer will be (3,11)
Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.
2x+5=3x+2
Then you subtract 2x on both sides to get the x's on the same side
and you get 5=x+2
Then you subtract 2 on both sides, and you get x to equal to 3
then you plug x into any equation to get y to equal 11
y= 2(3)+5
