Answer:
range = {-8,-5,-2,1}
Step-by-step explanation:
you can plug in each value for x.
Answer:
mi = 45(hr)
hr = mi/45
Step-by-step explanation:
Distance = 45 mph times the number of hours (time) D = 45t
time in hours = the number of miles (Distance) divided by 45 mph t = D/45
I believe your answer is b.
Answer:
a,e
Step-by-step explanation:
let length=l
width=w
height=h
surface area=2(l+w)×h+2×l×w
=2[lh+wh+lw]
2(8×4+4×3+8×3)=2(32+12+24)=2×68=136<160
2(7×6+6×4+7×4)=2(42+24+28)=2×94=188>160
2(3×7+7×8+3×8)=2(21+56+24)=2(101)=202>160
2(3×6+6×7+3×7)=2(18+42+21)=2(81)=162>160
2(3×5+5×7+3×7)=2(15+35+21)=2(71)=154<160
Answer:
(h o g) (x) = h(g(x))
Step-by-step explanation:
(h o g) (x) = h(g(x)) = 4(g(x))+1 = 4(2x^2 -3x + 1 ) + 1
= 4*2x^2 - 4*3x + 4*1 + 1
= 8x^2 - 12x + 4 + 1
= 8x^2 - 12x + 5
