How many times do the graphs of
the equations y = 2x + 4 and
y = -x + 4 intersect?

The graphs intersect one time

Step-by-step explanation:

we have

----> equation A

----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The graphs intersect only at one point

so

The system has only one solution

The intersection point is (0,4)

therefore

The solution is x=0, y=4

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
