Y = -23x + b
1 = -23(5) + b
1 = -115 + b, b = 116
Y = -23x + 116
I choose the slope intercept form since it was easy to calculate. The slope was given, you just need to plot in the points to find the y- intercept.

Answer:

I used the y=Mx+b equation because it has a good job showing each of the elements in the equation.

Step-by-step explanation:

The slope is -2/3 so if you add it to (5,1) it would be (3,4) as you just add three and subtract to to the point. I’m going to use for this equation as it is more simple and it gives a good job showing what each element is in the equation. M is the slope, so now we have y= -2/3x +b. To find b, substitute x and y for a point on this line which I will use the point (3,4) for. Now, multiply -2/3 by 3 and you will get -2 after. Now you have 4=-2+b which the answer would be 6.

This is just an example of finding the equation, which form I used, and why.

3 over 4 + 1 over 8

Dmitry [639]

Answer:

7/8

Step-by-step explanation:

Start by finding a common denominator. In this case you can turn the 4 into an 8 by multiplying by 2 but you have to do the same to the 3

2(3/4)= 6/8

Step 2: Add 6/8 + 1/8

6/8+1/8= 7/8

Please help me on this problem

<h2><em><u>Answer:</u></em></h2>

Total Surface Area = 375 $ft^2$

<h2><em><u>Step-by-step explanation:</u></em></h2>

You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls

<u>Area of the ceiling:</u>

c = length * width

c = 9*6.5 = 58.5

<u>Area of the 2 rectangle walls:</u>

w = 2(length * width)

w = 2(9 * 8)

w = 2(72)

w = 144

<u>Area of floor:</u>

f = 9 * 7.5

f = 67.5

<u>Area of the two trapezoids:</u>

$t = 2(h * \frac{a + b}{2})$

a = 6.5

b = 7.5

h = 7.5

$t = 2(h * \frac{a + b}{2})$

$t = 2(7.5 * \frac{6.5 + 7.5}{2})$

$t = 2(7.5 * \frac{14}{2})$

$t = 2(7.5 * 7)$

$t = 2(52.5)$

$t = 105$

Total Surface Area = c + w + f + t

Total Surface Area = 58.5 + 144 + 67.5 + 105

Total Surface Area = 375 $ft^2$
