Answer:
20
Step-by-step explanation:
if two trapezoids are the same proportions, and one is 3cm, and the other is 15, the makes that second 5 times larger than the first. therefore, the height is also 5 times larger
4 x 5=20
The scale factor is 2 or 200%
Answer:
XY=8
Step-by-step explanation:
In △XYZ, XY=XZ
It is isosceles triangle whose equal sides are XY=XZ
We are given,
XY=2a
YZ=3a+1
XZ=5a-12
XY=XZ
So, 2a=5a-12
Solve for a,
2a-5a=-12
-3a=-12
a=4
Now we put a=4 into XY=2a
So, XY=2(4)=8
Answer: The slope is -3/2
Step-by-step explanation:
To find the slope, find the difference in the y coordinates and divide it by the difference in the x coordinates.
y coordinates; 9 - 15 = -6
x coordinates : 8 - 4 = 4
Slope: -6/4 = -3/2
The function is only shifted vertically up 3 :)
