I hope you get this in time f (6) = 72
Explanation: f(6) = 2/3 • (6)^ + (8•6)
= 2/3 crossed out with 1 times 36 crosses out with 12 plus 48 = 24 + 48 = 72
So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
X - y = -3
y = x + 3.......slope = 1, y intercept = (0,3)
to find x int, sub in 0 for y and solve for x
x - y = -3
x - 0 = -3
x = -3....so the x intercept = (-3,0)
plot ur points (0,3) and (-3,0)......now start at (-3,0)....and since ur slope is 1, go up one, and to the right 1, and up 1, and to the right 1.....do this over as many times as needed and u should cross the y axis at (0,3)

Answer: x > -8</h3>
Multiply both sides by 2 so that you go from
x/2 > -4
to
x > -8
The inequality sign will not flip since we are not multiplying both sides by a negative number.
If you are curious how to graph the solution, draw out a number line and plot an open unfilled circle at -8. Then shade to the right of the open circle. The open circle says "do not include this value as part of the solution set". The solution set is shaded representing all of the values larger than -8 (which make the original inequality true).
Answer:
C
Step-by-step explanation:
combine like terms, 4 and -15 = -11
