Answer:
4:36
24 x 4:36
96:36
8:4
1day = 24 hours
Step-by-step explanation:
2x + y = -4
y = -2x - 4
differentiate:
y' = -2
m=-2 perpendicular = -1/m = -1/-2 = 0.5, x=2 y=-8
y=mx+c
-8=0.5(2) + c
-8 = 1 + c
-9 = c
y = .5x - 9
OR you can use y-y_1 = m(x - x_1), where x_1 = 2, y_1 = -8, m = 0.5
y - -8 = 0.5(x - 2)
y + 8 = 0.5x - 1
y = 0.5x - 9
same answer either way
hopefully i’m not too late.
the phrase “more than 10 t-shirts” immediately eliminates options A and C.
(C also doesn’t follow the correct variables)
now you just need to look at the variables and match them to the correct prices.
sweatshirts are $25, and the variable is s.
t-shirts are $10.50, and the variable is t.
D says that sweatshirts are $10.50 and t-shirts are $25, which is not what the information told us.
this will lead to the last option and your final answer, which would be B.
Answer:
To find the value of this expression you need to add and subtract from left to right
74.9+5.23-81.4-16 (add the first two, first)
80.13-81.4-16 (74.9+5.23=80.13) (next subtract the next two)
-1.27-16 (80.13-81.4=-1.27) (Last subtract the last two)
-17.27 (-1.27-16=-17.27)
-17.27
Hope this helps ;)
