Answer:
f(x) = -3x + 4
Step-by-step explanation:
3y = -9x + 12
y = -3x + 4
Well yeah it depends on the kids age and the parents age to
Slope intercept form is this:
y - y1 = m(x - x1)
We are given the point of (5, -4) and the equation y = 2x + 3
Our needed equation is parallel to the give equation, meaning it has the same slope which is 2
Plug in the slope which is 2x and the x1 and y1 values given.
y - (-4) = 2(x - 5)
Then, simplify the equation to receive our answer.
y + 4 = 2x -10
y = 2x - 14
y = 2x - 14 is our answer.
Let c be the chairs and t be the tables. This is a system of equations you are dealing with. The first equation tells us that 8 chairs (8c) plus 3 tables (3t) cost $38. So the equation is 8c + 3t = 38. The second equation tells us that 2 chairs (2c) and 5 tables (5t) cost $35. So that equation is 2c + 5t = $35. Solve this system any way you'd like. I used elimination and multiplied the second equation by -4 to get a new equation: -8c - 20t = -140. Now the 8c's eliminate one another leaving you with -17t = -102. Solving for t gives you t = 6. Now sub in that t value in either equation to give you that each chair costs $2.50
