Write the equation of the line in slope-intercept form using y=mx+b
Answers
Answer:
y = 1x - 4
Step-by-step explanation:
y = mx + b where the m is the slope and the b is the y intercept of where the line goes through the y. The M is how many squares it goes up or down. Since the line goes up 1 unit by 1 unit than the slope is 1. y = 1x + b. The line crosses the y at -4 meaning the y intercept is -4. Hope this helps!

A contractor is tiling your bathroom with one-foot square tiles. How many tiles are needed for the job? PLS HELPPP
Answers
Answer:
Depends on the bathroom
Step-by-step explanation:
Basically since I don't know the bathroom length and width, Ima just cut it down for you.
It is your bathroom area (length*width) divided by the area of the tiles, which is 1*1=1 foot^2(square)
Also it depends on the unit you used for the bathroom, you gotta transfer the unit for the bathroom length and width into feet.
So you should get number for bathroom area with the unit feet square.

1. 4.5x - 151.89
2. -2x + 375
Step-by-step explanation:
1.
Start with -$126.89
Small deposit: x (add)
Large deposit: 3.5x (add)
Withdrawal: $25 (subtract)
-126.89 + x + 3.5x - 25 =
= -151.89 + 4.5x
= 4.5x - 151.89
Answer: 4.5x - 151.89
2.
Start with $350
Small withdrawal: x (subtract)
Large withdrawal: x + 50 (subtract)
Deposit: $75 (add)
350 - x - (x + 50) + 75 =
= 350 - x - x - 50 + 75
= -2x + 375
Answer: -2x + 375
