First we have to replace everyone x with 2
2(4 . 2-10)³
2(8-10)³
2(-2)³
2(-8)
-16
Answer:
Please see attachment.
Step-by-step explanation:
Since there are no answer choices, I will just show you the graphs for each one.
Remember the dashed lines means it is either greater than, or less than.
The solid lines are either greater than or equal to, or less than or equal to.
Hope this helps!
If not, I am sorry.
Answer:
(x, y) = (-2, 3)
Step-by-step explanation:
In this form, it is easy to determine the x- and y-intercepts of each equation. That makes it easy to graph the first one, but not so easy to graph the second one on the given form.
The x-intercept is found by solving for x when y=0. In the two equations, the x-intercepts are ...
x = 4
x = -8 . . . . . . not shown on the given grid
__
The y-intercepts are found by solving for y when x=0. In the two equations, the y-intercepts are ...
y = 4/2 = 2
y = -8/-2 = 4
__
For the second equation, you can solve for y to put it in slope-intercept form.
x -2y = -8
x +8 = 2y . . . . . add 2y+8
y = 1/2x +4 . . . . . . . slope = 1/2, y-intercept = 4 (which we already knew)
This means the graph of the second equation will have a rise of 1 for each run of 2 units to the right. Working to the left from the y-intercept, we find another point to be (-2, 3), a point 2 left and 1 down from the y-intercept. This point is also on the line produced by the first equation, so (-2, 3) is the solution to the system.
Given :The scented burns inches in 20 minutes
The scented candle will burn inches in one hour.
The unscented candle burns inches in 30 minutes
In one hour it will burn inches .
Burn rate of scented is inches per hour.
Burn rate of unscented is inches per hour.
