BlackZzzverrR [31]

Answer:

x = 45.25 and 2x + 9.50 < 100

Step-by-step explanation:

Okay, so I dont know if you want am explanation but here I go

if for each game shipping is 4.75, you multiply by 2 to find the total there, hence 9.5.

and you dont want to go over $100, so the amount you spent has to be less then $100

and you're going to buy 2 games, x stands for the price.

2x + 9.50 < 100

2x < 90.5 (i just subtracted 9.5 on each side)

2/2x = 90.5/2

x = 45.25

Write the equation of the line that passes through (4,2) and is parallel to the line y=2x-1
Mariulka [41]

Answer: y = 2x-6

Step-by-step explanation:

So we need to write the equation of a line parallel to y=2x-1.

In parallel lines, the slope is the same, so in our new line the slope will be 2x.

We have the equation y = 2x right now. Let's plug in (4,2) for (x,y) and see if it works out, since it must pass through that point.  

y = 2x

2 = 2 * 4

2 doesn't equal 8.  

But if we subtract 6 from the right side of the equation -

y = 2x-6

then it checks out

2 = 2 (4) - 6

2 = 8 - 6

2 = 2
