10/21+(2/3-1/7)=1

10/21+ ( 2/3(7) =14/21 - 1/7(3)=3/21)
10/21+11/21=21/21
21/21 = 1

I hope this helps.

Answer both questions!

vodomira [7]

1) What is the equation for the line?
slope = 16/2 = 8

answer
equation
y = 8x

2) What is the equation of a line with a slope of 3 and a point (3, 1) on the line?

Express the equation in the form of y=mx+b where m is the slope and b is the y-intercept.

y - 1 = 3(x - 3)
y - 1 = 3x - 9
y = 3x - 8

answer
y = 3x - 8

Nuetrik [128]

Answer:

They need 2 and 1/2 rolls.

Step-by-step explanation:

Area = length x width

A = l x w

A = 20 x 3

A = 60 ft²

If 60 ft² = 1 roll

What about 150 ft² = ?

= (150 x 1) ÷ 60

= 150 ÷ 60

= 2.5

= 2 and 1/2 rolls

Y=3x-4
This affects the previous line because now the slope is a positive which completely turns it around. and the Y intercept is now on the opposite side of the X axis
