Answer:

y=4x-2

Step-by-step explanation:

for every 1 unit increase in x, y values change by a factor of four units

slope=4x

f(x)=y

y=mx+b

2=4(1)+b

b=-2

equation= y=4x-2

CHECK

6=4(2)-2

6=8-2

6=6

CORRECT

10=4(3)-2

10=10

CORRECT

alternatively... (y2-y1)/(x2-x1)

(6-2)/(2-1)= (4)/(1)

slope=4

Find equation where line passes through (7,8) and perpendicular to line y=8
forsale [732]
Since in y=8, the slope is 0 (because there is no x) and b is 8 in y=mx+b, we know that the perpendicular line is x=(something) because the perpendicular lines of y=<number> are x=<number> due to that y=<number> equations are strictly horizontal while x=<number> equations are strictly vertical. Since we know that x=<number> has to pass through (7, 8), x =7

PLEASE HELP ME I DON T UNDERSTAND IF YOU PLEASE COULD HELP ME I WOULD GREATLY APPRECIATE IT REALLY THANK YOU
butalik [34]

Find the length of one side.

V = s^3

s = cube root of V

V = 729

s = cube root 729

s = 9

Put this into your calculator as 729^0.333333333

It should bring back 9 or 8.999999 something which means 9.

Net

The net is shown below. You will have to do the labeling. But I can tell you what you should label each face as?

Area of one face = s^2

s = 9

Area of one face = 9*9

Area of one face = 81

So when you draw this, each face should be labeled with 81.

It should have it's units (ft^2) if your marker is picky.

Part C

There are 6 sides.

1 side has an area of 81 ft^2

6 sides have an area of 6*81 = 486 ft^2

What is the quotient of 99 divided by 9081
Artist 52 [7]

Hello from MrBillDoesMath!

Answer:

11/ 1009   (.0109 approximately)

Discussion:

99/9081 =                               => as 9081 = 9 * 1009 = 3 * 3 * 1009

99/ ( 3 * 3 * 1009)  =

(99/(3*3)) * (1/1009) =

(99/9)  * (1/1009)  =

11/ 1009 =

.0109 approximately


Thank you,
