Answer:
x = -2
Step-by-step explanation:
2(4x+8)
= 8x+16
8x+16 = 0
-16 -16
8x = -16 (do -16÷8 & get)
x = -2
Answer:
Option B is correct friend
The relationship is a function. A function is an equation of graph that has no repeated x values. In this graph, each x value has a different y value, whether it's (1, 70) or (9,95)
If Rachel gets anything other than a 95, the x value of 2 will have more than one y value: 95 and whatever grade Rachel gets. Therefore it will no longer be a function.
Answer:
y = -5x + 4.
Step-by-step explanation:
y = mx + c is the general form
- where m = the slope of the line and c is the y-value where the graph cuts the y-axis.
The graph passes through the points (0, 4) and (1, -1) so the slope
= (Y2 - y1) / (x2 - x1)
= (-1-4) / (1-0)
= -5 = m.
and c = 4.
