Answer:
(3,8)
Step-by-step explanation:
f(3)= 4 so y=f(3) +4 y =8 when x =3
The correct answer is 5, 3. As x increases by 1, y increases by 1 as well.
Therefore the answer is 5, 3
Answer:
The first equation should be multiplied by 9 and the second equation by −4
Step-by-step explanation:
Given the simultaneous equation
First Equation: 5x − 4y = 28
Second equation: 3x - 9y = 30
In order to eliminate y, we must make the coefficient of x in both expression to be equal.
To do that the first equation should be multiplied by 9 (negative value of the coefficient of y in equation 2)and the second equation by -4( (coefficient of y in equation 1)
