Step-by-step explanation:
x2-8x-3x+24=0
x(x-8) 3(x+8)
(x-8)(x+8)
x-8=0 or x+8=0
x=8. x= -8
Answer:
A, C, and D
Step-by-step explanation:
The rate of change will simply be the slope of the line, which we can find by taking the change in y and dividing that by the change in x:
slope =
Thus, the slope is 3/2 = 1.5.
Since the slope remains constant throughout the graph, we know that A is correct. In addition because the points 0, 2, 4, and 6 are on the graph, the rate of change between any of the two points will still be the constant 1.5, making C and D correct as well.
So, we can choose A, C, and D.
Hope this helps!
Answer:
x=3, y=1. (3, 1).
Step-by-step explanation:
x+3y=6
2x-7y=-1
------------
x=6-3y
2(6-3y)-7y=-1
12-6y-7y=-1
12-13y=-1
13y=12-(-1)
13y=12+1
13y=13
y=13/13
y=1
x+3(1)=6
x+3=6
x=6-3
x=3
