Answer:
the one on the right y=4x
Step-by-step explanation:
even if u switch out x it will yeah
Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
-7x-5y=-47x+9y=-4
combine like terms to cross out the 7x
solve for y, to get -2
plug it back in to one of the equations and x is 2
y=-2
x=2
Answer:
The solution to the system of equations be:
Hece, option B is correct.
Step-by-step explanation:
Given the system of equations
Multiply x − 3y = 6 by 2: 2x-6y=12
so
so the system of equations becomes
Solve 8y = -8 for y
Divide both sides by 8
subtract 6 from both sides
Divide both sides by 2
Therefore, the solution to the system of equations be:
Hence, option B is correct.
