How to graph 6x + 3y = 12
explanation:

Step 1: Find x intercept: substitute 0 for y: solve for x

• 6x + 3(0) = 12
• 6x = 12
• x = 2

Step 2: Then Find y intercept: also substitute 0 for x; solve for y

• 6(0) + 3y = 12
• 3y = 12
• y = 4

So plot x and y intercepts: ( 2,0 ) and ( 0,4 ) then draw a line through the points.

How to graph 3x + y = 5
explanation:

Step 1: Find x intercept: substitute 0 for y: solve for x

• 3x + 5(0) = 15
• 3x = 15
• x = 5

Step 2: Then Find y intercept: also substitute 0 for x; solve for y

• 3(0) + 5y = 15
• 5y = 15
• y = 3

plot x and y intercepts: (5,0 ) and ( 0,3) then draw a line through the points.

Hope this help:))

A farmer has 90 feet of fence with which to make a corral. If he arranges it into a rectangle that is twice as long as it is wid
Leya [2.2K]

Answer:

W = 15 ft. and L = 30 ft.

Step-by-step explanation:

Perimeter = 90 ft.

Twice as long as it is wide: L=2W

P = 2(L + W) = 2(2W + W) = 6W

90 = 6W

W = 15 ft. and L = 30 ft.

Write the formula to calculate how much dough is prepared in x hours.
spin [16.1K]

Answer: D(x) = 2kg/h*x

where x is the number of hours.

Step-by-step explanation:

The information that we have is:

in 5 hours, we can prepare 10kg of dough.

With this, we can find the rate per hour, to do this we find the quotient:

R = 10kg/5h = 2kh/h

This meeans that in one hour, we can make 2kg of dough.

Then, in x hours, we can make x times 2kg of dough, then the equation will be:

D(x) = 2kg/h*x

where x is the number of hours.
