Answer:
263.76
Step-by-step explanation:
It is 7 times 12 times 3.14. Then you round your answer
The top right one is not a function
Step-by-step explanation:
The equivalent expression of 8x + 12 - x = 7x + 12
Answer: X-intercept is (2,0)
Y-intercept is (0,-2)
Step-by-step explanation:
Answer:Since -2 can not equal 0, there is no solution. The lines are parallel. It is an inconsistent system.
Step-by-step explanation:
The first step in solving a system of equations by substitution is solving one of the equations for one of the variables
x - y = 0 Equation 1
x - y + y = 0 +y Add y to each side
x = y Simplify
After solving an equation for one of the variables, substitute that value into the other equation. In this problem, I can substitute y for x.
x - y - 2 = 0 Equation 2
y - y - 2 = 0 Substitute the value of x from equation 1
0 - 2 = 0 Inverse Property of addition
-2 = 0 Identity Property of addition
