if you take 14.45 and divide it by 5 you get $2.89
which makes it 2.89 a pound. so 2.89 multiplied by 7 gets you $20.23
Answer:
y=-1x-2
Step-by-step explanation:
First, find the slope using the formula of y2-y1/x2-x1 and then plug it in for m.
Lastly, use one of the y points from either points for your y int.
Hope this helped!
Answer:
The x Intercepts of y=5x^2-15x is (1, 0) and (-1, 0)
Step-by-step explanation:
Answer:
12 nickels and 9 dimes
Step-by-step explanation:
1/ We have: n + d = 21 <=> d = 21 - n or opposite (n = 21 - d)
2/ We have: 0.05n + 0.10d = 1.50 and then we will put 1/ into 2/
=> 0.05n + 0.10(21 - n) = 1.50
=> 0.05n + 2.1 - 0.1n = 1.5
=> -0.05n = -0.6
=> n = 12
Nevertheless, d = 21 - n = 21 - 12 = 9
Answer:
If the given equation is
comparing with
Therefore, the option is correct.
Step-by-step explanation:
Given
We know when varies directly with , means that when x increases, y increases by the same factor
i.e.
y ∝ x
where k is the 'constant of proportionality.
If the given equation is
comparing with
Therefore, the option is correct.
