I’m going to say pre-algebra because that’s when I learned it in my school system but you may also learn it in algebra as well, College ready math can start in 8th grade math but I would think it would be in highschool.
First you need to find the area of the floor to know how much wood you need
Area=lengthxwidth, so A=40x14.5 which equals 580 square ft
With a floor that's 580 square ft and the boxes cover 18 Sq ft each then all you have to do is 580/18= 32.222 and because you can't buy .222 of a box you need to round up to 33 boxes
Let's take the first 2 x and y values and use them. First, you need to fill in your formula: y2-y1/x2-x1. It should look like this: 5-2/4-2. Then solve and you should get 3/2. You can't simplify it. So, this is your slope.
Next, you need to put this is into another formula. The formula is y-y1=m(x-x1). Take the first coordinate pair and plug it in for x1 and y1. Plug in your slope for m. When it's filled in, you should have y-2+3/2(x-1). It's hard to explain how to solve it so i'll just write it out.
y-2=3/2(x-2)
y-2=3/2x-3
y=3/2x-1
So, we have our equation in slope intercept form so that we have our slope and our y-intercept.
Y-intercept: -1
Slope: 3/2
Please put this as brainliest it took awhile and I hope this helped :) reply with questions if you still need help or have questions about the steps
B=-3.4 if you want an explanation just ask
Answer:
z≥−3
Step-by-step explanation:
1 Subtract 88 from both sides.
5z≥−7−8
2 Simplify -7-8−7−8 to -15−15.
5z≥−15
3 Divide both sides by 55.
z≥− 15/5
4 Simplify 15/5 to 3
z≥−3
