Answer:
-73
Step-by-step explanation:
s(-8) = 7(-8) - 17
s(-8) = -56 - 17
s(-8) = -73
It’s (-8z^2 +8x +4y -2z)
Hope it helps
T = 126.
13 = t/9 - 1 multiply both sides by 9
117 = t - 9 move terms
-t = -9 - 117
-t = -126 change the signs
t = 126
42672. multiply 4 times 23028 and then multiply 5 times 9888 then subtract
Answer:
a. 12.5
Step-by-step explanation:
Scale factor of ∆LMN to ∆XYZ = 2:5
To find length of side ZX, set the ratio of the corresponding sides of interest equal to the scale factor.
Thus:
ZX corresponds to NL = 5
NL:ZX = 2:5
5:ZX = 2:5
5/ZX = 2/5
Cross multiply
5*5 = ZX*2
25 = ZX*2
Divide both sides by 2
25/2 = ZX
12.5 = ZX
ZX = 12.5
