4x-2 is the answer to 3x+2+x-4
Answer:
A=1/2bh
Step-by-step explanation:
The area A of a triangle is given by the formula A=1/2bh where b is the base and h is the height of the triangle.
So for example if you got that the base of the triangle is 12 and the height is 14 you would plug it in like this:
A=1/2(12)(14)
A=6(14)
A=84
Answer:
The dependent variable is c
Step-by-step explanation:
The cost of lunch changes with each day, so the cost depends on the number of days
Answer:
(9,0) and (-4,0)
Step-by-step explanation:
First, move everything to the left to make the whole equation equal to 0.
So we get x^2-5x-36=0
Then we can factor by finding the two numbers that multiply to -36 and add to -5.
Those two numbers are -9 and 4.
So we have (x-9)(x+4)=0.
So the two roots are 9 and -4.
To verify this on a graphing calculator, plug in the equation and look at the x intercepts.
If they match up with (9,0) and (-4,0) you have your answer.
