Answer:

Steps below, ask if you need further explanation.  

Step-by-step explanation:

You've graphed the points, but it wants the lines and their equations.

Horizontal lines are of the form y=a, where a is the y value the line is at.  Verticla lines are of the form x=b, where b is the x value the line is at.  horizontal lines have a slope of 0 and vertical lines have an undefined slope, I will show you why.

Slope is found by (y2 - y1)/(x2 - x1) where (x1, y1) and (x2, y2) are the two points you are finding the slope between.  A horizontal ine has no change in x s y2 - y1 = 0 so the fraction becomes 0/(x2-x1) = 0, so the slope is 0.  No change in x makes the denominator 0, and dividing by 0 is undefined.  

For the slanted line you will get a non zero or undefined slope, ets call it m.  Then to find the line just plug into the formula y1 - y = m(x1 - x) where m is that slope and (x1, y1) is ONE of the poitns you are measuring the slope of.  You just choose one, they will both get the same answer.  Then just solve for y.  Not y1, you want just y on one side of the equation.

Let me know if you need more explicit walking through.

Solve for x. Round to the nearest tenth, if necessary.
Tcecarenko [31]

ANSWER

14.3

EXPLANATION

angle = 21⁰

opposite side = 5.5

adjacent side = x

Knowing this, we must use tangent (opposite / adjacent)

tan (21⁰) = 5.5 / x

x = 5.5 / tan (21⁰) (use calculator)

x= 14.3

Jaun has 105 feet of rope he needs to cut into sections 7/8 feet long . how many sections can be cut
AVprozaik [17]

The answer is 120 sections.

Here's an explanation:

The rope is 105 feet long, and each section needs to be 7/8 feet. So to find the number of sections, you need to divide 105 by 7/8. 105 divided by 7/8 gives you the quotient 120. So there are 120 sections.

Solve the equation for y<br> Y minus 5 equals 1/3 (x plus 12)
Vinvika [58]

Answer:

ok so this problem you are basically just rearranging it. you're going to want y by itself.

Step-by-step explanation:

let's start with the original equation: 5-y=1/3x +12

so first you have to move the five over, so you subtract 5 from both sides. -y=1/3x+12-5

then you subtract the 5 from the twelve since they're like terms: -y=1/3x+7

and finally you have to move the negative over. when you move the negative think of it like dividing negative one from both sides, everything on the other side has to get the negative.

so we're left with y=-1/3x-7

I hope this helps!

Calculate the trade discount for 3030 boxes of computer paper if the unit price is ​$14.9314.93 and a single trade discount rate
zhannawk [14.2K]

Answer:

Total trade discount on 30 boxes = $201.555

Step-by-step explanation:

1 box = $14.93

And a trade discount of 45% is allowed on a single box,

Therefore, the discount on one $14.93 box will be

45% × $14.93 = $6.7185

So, if there are now 30 boxes, the trade discount on all 30 boxes will be

30 × (trade discount on one box) = 30 × ($6.7185) = $201.555

Hope this helps!
