Does dilation preserve angle measure?
When a point, side, line, or angle is dilated; the length of the line will be altered by the ratio or scale of dilation.
However, the measure of angle will remain the same.
<em>Hence, the given statement is true.</em>
Answer:
Graph (6, 5) and (-6, -3), and then use a ruler (optional), and draw a line between them, and a little after the points.
Step-by-step explanation:
y = 2/3x + 1
Substitute different numbers for x, and find y:
You don't really want to work with fractions, so try to find a number that when multiplied by 2/3, gives you a whole number
x = 6
y = 2/3(6) + 1
y = 12/3 + 1
y = 4 + 1
y = 5
Point: (6, 5)
x = -6
y = 2/3(-6) + 1
y = -12/3 + 1
y = -4 + 1
y = -3
Point: (-6, -3)
Graph these two points, and then use a ruler (optional), and draw a line between them, and a little after the points.
Equation 1:
2x + y = 25
-Subtract 'y' to both sides (quick note: pretend 'y' is '1')
2x + 1 - 1 = 25 - 1
2x = 24
-Divide '2' to both sides
2x/2 = 24/2
x = 9
Equation 2: 3y - x = 20
-Add 'y' (or 1) to both sides
3y - 1 + 1 = 20 + 1
3y = 21
-Divide '3' to both sides
3y/3 = 21/3
y = 7
Answer: (0, -4)
Step-by-step explanation:
Answer:
the correct answer is:
68 + x + ( x-24) =180
x + (x-24) = 112
2x - 24 = 112
2x = 112 + 24
2x = 136
x = 68
so ...for another : 68 - 24 = 44
