If you are asking how many hot dogs and cans of soda are sold, this is how I solved it.
Given:
cost of hot dog $3
cost of a can of soda $1
total items sold: 350
total sales: $624
let h stand for hot dog and s stand for soda.
h + s = 350
3h + 1s = 624
h = 350 - s
3(350-s) + s = 624
1,050 -3s + s = 624
-2s = 624 - 1050
-2s = -426
-2s/-2 = -426/-2
s = 213 cans of soda
h = 350 - s
h = 350 - 213
h = 137 hot dogs
3h + s = 624
3(137) + 213 = 624
411 + 213 = 624
624 = 624
Mitchell sold 137 hot dogs and 213 cans of soda.
Answer:
<em><u>The answer is m(x) </u></em><em><u>= -7x =</u></em><em><u>A function will only have an inverse function if the function is one-to-one. If you graph the function out and it passes the horizontal line test, it is one-to-one. Only the function m(x) = -7x will have an inverse that is a function. The graph of y = m(x) is a linear function. Linear functions pass the horizontal line test (it's symmetric about the y-axis). The function does not have an inverse that is a function because the graph of b(x) is parabolic. It will fail the horizontal line test when you graph it out. The function does not have an inverse that is a function because the graph of d(x) is a horizontal line. A horizontal line fails the horizontal line test because it is a horizontal line. The function does not have an inverse that is a function because the graph of p(x) fails the horizontal line test (it's symmetric about the y-axis).</u></em>
Answer:
It's -539
Step-by-step explanation:
539 is a positive number in this one, so to find the opposite, you'd make the number a negative one, which is -$539
Answer is
Choice C
I used the power rule for integrals.
