T(z)=z-8
T(-2)=-2-8 therefore
T(-2)=-10
Hope this helps.
Answer:
(- 4, 9 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 24 → (1)
3x + 2y = 6 → (2)
Subtract (2) from (1) term by term to eliminate x
3x - 3x + (4y - 2y) = 24 - 6
2y = 18 ( divide both sides by 2 )
y = 9
Substitute y = 9 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(9) = 24
3x + 36 = 24 ( subtract 36 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
solution is (- 4, 9 )
Answer:
B. 203.403
Step-by-step explanation:
2 times 100 = 200
3 times 1 = 3
4 times 1/10 = 0.4
3 times 1/1000 = 0.003
200 + 3 = 203
203 + 0.4 = 203.4
203.4 + 0.003 = 203.403
I don't know what you're asking. Is the question asking for the area, or perimeter of the store? for perimeter, the answer is 162 meters, and for area the answer is 1638
