Answer: (C) y= x − 2
Explanation:
y=x-2 is the choice that satisfies all the points in the table. This can be verified case by case:
y=x-2
(-3,-5): -5 = -3 -3
(-1,-3): -3 = -1 - 2
(1,-1): -1 = 1 - 2
(3, 1): 1 = x - 2
(5,3): 3 = 5 - 3
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
Its radical 49 :) (by radical 7 means square root of 7)
Answer:
y = 13
z = 11
Step-by-step explanation:
14. We know that if the two triangles are congruent, then the hypotenuses will be the same. So we can say that
6y = 5y + 13
We can solve for y by subtracting 5 y from both sides and find out that y = 13.
15. Again, we know if the triangles are congruent then the two shorter legs will be the same, so we can say that:
3z = z + 22
2z = 22
z = 11
