Answer:
The given matrix is telling us that we must translate the figure one unit to the right side and one unit downside because the first row states 0 x-units and -1 y-units, the second row states 1 x-unit and 0 y-units.
The transformation of the coordinates would be
(1,-1) to (2, -2)
(2,1) to (3, 0)
(4,1) to (5, 0)
(4,-1) to (5, -2)
The image attached shows the representation of the image.
Answers:
- x = 4
- AB = 36
- BC = 36
- AC = 36
All three sides are 36 units long.
===========================================================
Explanation:
Triangle ABC is equilateral, so all three sides are the same length.
Pick any two of those sides, set them equal to each other, and solve for x
AB = BC
8x+4 = 11x-8
8x-11x = -8-4
-3x = -12
x = -12/(-3)
x = 4
Use this x value to find each side. We should get the same value (if not, then an error occurred in solving for x).
- AB = 8x+4 = 8*4+4 = 32+4 = 36
- BC = 11x-8 = 11*4-8 = 44-8 = 36
- AC = 9x = 9*4 = 36
We get the same value for the three side lengths, so this confirms we have the correct x value.
Answer:
the answer is the second to the left :D
Step-by-step explanation:
each number is divided then you solve\
1/4 of 180 gets you the answer 45
Answer:
a) The domain is the set of the possible values of x.
In the graph, we can see that x goes from - 4 to 4
So the domain is: D = x∈ {-4, 4)
b) The zeros are the points where the graph cuts the x-axis.
Those values are:
x = -2
x = 0
x = 2.
c) The graph is positive if it is above the x-axis and it is negative if it is below the x-axis.
in the interval {-4,0} the graph is bellow the x-axis, so in this interval the function is negative.
in the interval {0, 2} the graph is above the x-axis, so in this interval the function is positive.
in the interval {2, 4} the graph is bellow the x-axis, so in this interval the function is negative.
