Answer:

I will say this idk if you learn by reading or watching better, so if it's reading then read on! but if it's watching then look up "how to graph lines" and there is a bunch of videos!

Step-by-step explanation:

so you have y = 3x - 2 so first on the y axis your start point will be (0, -2)

then refer to rise over run ( rise/run) where rise is up(on the y axis) and run is across on the x axis.

so you start at (o, -2) and up 3 points on the y axis and across 1 point (go left) and mark it and repeat( up 3 across 1) until you reach the top of the graph

then finish the graph so repeating this going to the bottom is the same but different directions:

so go back to (0, -2) and go down 3 points (y axis) and across 1 point(this time go right on the x axis) and repeat until you reach the bottom and then use the points you marked to trace a line and boom your done! (this explanation is only for number 10)

same rise over run but different points and possibly line direction.

so for number 11: your starting point is (0, 3) and you go up 4 point and across 1 point but this time go across to the right. repeat. once you at the top of the graph go back to (0, 3) and go down 4 points and 1 point to the left. repeat. until you reach the bottom. trace the line.

number 12: a bit more tricky. starting point is (0, 5) for this one you go up 6 points and across 5 to the right. repeat. until you get to the top then go back to (0, 5) and go down 6 points and across 5 to the left. repeat. once you reach the bottom trace your line. then done! Sorry to inform you I don't know about 13 and 14! :(

Bonus but still important: the reason why you are going left and right on some of the lines is because the + or - in your equations tell you which direction the line is facing, toward the left (on the top part of your graph) would be - and toward the right part of your would be a + in the equation

More Bonus: a formula Is y=mx + b (0, b)( for ex: 0,5) is the starting point and (mx or for ex 4x is the amount you go up and across. When there is a x that always means across 1 and when there is not a x (ex: 6/5) it's across whatever the 5 is. ex: 6/6 is up 6 and across 6

Hope this helps!

Answer:

$5m^6 - 10m^5 - 5m^4$

Step-by-step explanation:

All you need to do is distribute the $5m^4$ to ( $m^2-2m - 1$ ), like so:

( $m^2-2m - 1$ ) $(5m^4)$

$5m^6 - 10m^5 - 5m^4$

A family pass to the amusement park costs $54 Using the Distributive Property,write an expression that can be used to fine the c

ruslelena [56]

The distributive property is: a(b + c) = ab + ac. In this expression, the example would be 8(54 + 0) = (8 x 54) + (8 x 0). The cost of eight family passes is therefore equal to 8 x 54. $432 is the answer.

Bond [772]

Answer:

Step-by-step explanation:

Your numbers are stated in terms of miles. Greenville is a total of 120 miles from Rick. He drives x number of miles and sees that there is still 20 miles to go, so at the end of the driving, he has driven the unknown number of miles, x plus the 20 to get where he's going. That expression is x + 20. We set that equal to the total number of miles he has to drive and we get the expression for the trip to be x + 20 = 120, option C.
