Answer:
a. 2/5; reduction
Step-by-step explanation:
It appears that C is the center of dilation, so C' and C are coincident. The scale factor is ...
P'C'/PC = 4/10 = 2/5 . . . scale factor
The scale factor is less than 1, so the dilation is a <em>reduction</em> in size.
Perpendicular lines meet each other always at an angle of 90 while intersecting lines may or may not have an angle of 90.
Their opposite angles(made by intersecting lines) are always same.
And even, we can say every perpendicular lines as intersecting but can't say that every intersecting line is perpendicular.
We can use the points (-10,0) and (-13,3) to solve.
Slope formula: y2-y1/x2-x1
= 3-0/-13-(-10)
= 3/-3
= -1 (Answer)
Hope This Helped! Good Luck!
Answer:
-2
<em>BRAINLIEST, PLEASE!</em>
Step-by-step explanation:
5 - 3(2a + 1) = -4a + 10
5 - 6a - 3 = -4a + 10
2 - 6a = -4a + 10
-2a = 8
a = -4
-4 + 2 = -2
