Answer:
x= -1/3
Step-by-step explanation:
2x+7x=-3
9x/9= -3/9
x = -1/3
Answer:
540 is the answer i think
The cost of bananas = $ 3.48
This can be written as :
this number written in expanded notation as : (3 × 1) + (4 × 0.1) + (8 × 0.01)
3+0.4+0.08 = 3.48
Hence, 1st option is correct.
Answer:
answer is 52 cm
Step-by-step explanation:
BA = 17, BF = 6, and CG = 9
triangle sides BF and BH are congruent because they are tangent lines along the same curve
BH is equal to 6 since BF is equal to 6
this applies to CG and CF and AG and AH
CG is equal to 9
so CF is equal to 9
now we add 6 + 9 for the measurement of side CB
CB = 15
now we do the same for the other two sides
we already know BA = 17 so we subtract it from BH = 6 to find the measurement of AH
AH is equal to 11 and is tangent across the same curve as AG
AG = 11
now we add AG to CG
11 + 9 = 20
now we know all the side lengths
CB + BA + AC = Perimeter
15 + 17 + 20 = 52
Perimeter of triangle BCA = 52
I don't know why I went through all the trouble if I know no one is going to see this :'(. I just thought the other guy gave the wrong reasons
<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>
