Answer:
Step-by-step explanation:
3z = 12
z = 4
5y - 4 = 1
5y = 5
y = 1
2x + 1 - 4 = -7
2x - 3 = -7
2x = -4
x = -2
(-2, 1, 4)
<span>Let x = dollar increase in price
Let y = fewer number of pairs sold
Since 2 fewer shoes are sold for each 1 dollar (factor of 2)
y = 2x
Revenue = Number of shoes sold * Price charged per shoe
Number of shoes sold = 200 - y = 200 - 2x
Price charged per shoe = $60 + $x
Revenue = (200 - 2x)(60 + x) = -2x^2 + 200x - 120x + 12000
Revenue = -2x^2 + 80x + 12000
In a quadratic equation, Revenue is maximized when x = -b / 2a. In this case:
x - -80 / (2*-2) = $20
Price charged per show = $60 + $x = $60 + $20 = $80.
Maximum revenue = -2x^2 + 80x + 12000 (evaluated at x = $20)
Maximum revenue = -2(20^2) + 80*20 + 12000 = $12800</span>
See how if the number (1-4 u would round down, 5-9 u round up) u would look at the place value it asks then look at the one next to it and see if u round up of down so it would be 17.3
Answer: y=4√3≈6.93
Step-by-step explanation:
We know that:
You know that the triangle is a right triangle and you also know the measure of the hypotenuse. Therefore, you must calculate the opposite side y as following:
sin(60°)=opposite/hypotenuse
Where:
opposite=y
hypotenuse=8
Now, when you substitute and solve for the opposite side, you obtain the following result:
y=8*sin(60°)
y=4√3≈6.93
