Answer:
y = 80-16x
Step-by-step explanation:
She made a total of 80 cups and sells 16 cups per hour
So in x hours she would have sold 16 * x = 16x cups
So the number of cups remaining will be;
y = 80-16x
The probability of *NOT* getting all 11 tails is 91/100
Step-by-step explanation:
5x + 2x
that is the same as (5 + 2)x
and that is the same as (7)x = 7x
so, for the second part of the problem we are actually comparing
7x
and
7x - 1
there is therefore no way for the two expressions to deliver the same value for the same x.
the values of 7x are always larger by one than the values of 7x - 1
so, e.g.
x = 1
5×1 + 2×1 = 5 + 2 = 7
7×1 - 1 = 7 - 1 = 6
x = 2
5×2 + 2×2 = 10 + 4 = 14
7×2 - 1 = 14 - 1 = 13
x = 3
5×3 + 2×3 = 15 + 6 = 21
7×3 - 1 = 21 - 1 = 20
x = 4
5×4 + 2×4 = 20 + 8 = 28
7×4 - 1 = 28 - 1 = 27
x = 5
5×5 + 2×5 = 25 + 10 = 35
7×5 - 1 = 35 - 1 = 34
Answer:
D
Step-by-step explanation:
Clockwise would mean a rotation to the right, and since the triangle is already plotted, just use the little picture turning icon( in the top right corner of the photo of the problem) to turn, and look at the triangle in the original graph to see how it moved.
Then click the button three more time until you get the photo right-side-up, and choose which option is the best answer.
