Answer:
The length is 2.5 units
Step-by-step explanation:
Before we find the value of the length of the side, we need the measure of the coordinates after dilation
B’ = 1/2 B = 1/2(3,2) = (1.5, 1)
C’ = 1/2 C = 1/2( 0,-2) = (0,-1)
The measure of the length is the distance between the two points
Mathematically, that would be;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(0-1.5)^2 + (-1-1)^2
D = √(2.25 + 4)
D = √6.25
D = 2.5 units
Answer:
25% Decrease
Step-by-step explanation:
15/20 is 75%. 100-75 (since they read less) is 25%
Answer:
Plz mark me brainliest!!!!
Step-by-step explanation:
0
90
180
270
380
3x-10+2x=115
5x-10=115
5x=125
x=25
m<b=3(25)-10=65
m<C=2×25=50
10P4 = 10! / (10-4)! = 10*9*8*7 = 5040
9C4 = 9! / 5! 4! = 9*8*7*6 / 4*3*2*1 = 126
