T(4,-1) means move 4 units to the right and 1 unit down.
Based on the image, M(-3,4) ; N(-2,1) ; P(-4,2)
So,
M:
-3 move 4 units to the right becomes 1
4 move 1 unit down becomes 3
M'(1,3)
N
-2 move 4 units to the right becomes 2
1 move 1 unit down becomes 0
N"(2,0)
P
-4 move 4 units to the right becomes 0
2 move 1 unit down becomes 1
P''(0,1)
Answer:
X = 0
Y = -3
Step-by-step explanation:
In this situation you would choose elimination.
-6x+y=-3
7x-y=3
---------------
x = 0
plug back in to find y
(-6)(0) + y = -3
0 + y = -3
y = -3
plug in to other equation for double check
7(0) - (-3) = 3
0 + 3 = 3
3 = 3
Hope this helps
Answer:
This is not a good model because the residual plot becomes thicker at the end
Answer:
x = 11.4 m
y = 21 m
man's shadow = 9.6 m
Step-by-step explanation:
measure of third angle must be 50 degrees (180 - (40 + 90))
you can take tan50° = 15/y and 'y' will equal approx. 21
to find 'x' you can take tan21° = (21-x) /25 and 21 - x = 25 · tan21°
21 - x = 9.6
-x = -11.4
x = 11.4
man's shadow is the difference of 21 and 11.4, which is 9.6
