Answer:
(5, )
Step-by-step explanation:
Given the 2 equations
5x + 7y = 40 → (1)
3x - 7y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
8x + 0 = 40
8x = 40 ( divide both sides by 8 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
5(5) + 7y = 40
25 + 7y = 40 ( subtract 25 from both sides )
7y = 15 ( divide both sides by 7 )
y =
solution is (5, )
Answer: plot a point at (-8, -5)
The y coordinate flips from positive to negative, or vice versa, when we reflect over the horizontal x axis. The x coordinate stays the same.
The rule can be written as
Answer:
(3, -1) is the answer to this problem.
Answer:
A
Step-by-step explanation:
It will be -x^2 because the parabola if facing downward. It is -4 because -4 is the y intercept.
