The ratio of selling price to cost price is. 3.65 : 1.72
The cost price is 28.50 and you want to find the selling price so let x replace that spot
x : 28.50
cross multiply 3.65 × 28.50 and 1.72 × x
3.65 × 28.50 = 104.025
1.72 × x = 1.72x
104.025 = 1.72x
x is approximately $60.48
Answer:
Option D does not have an x-intercept. Please se attached graph
Step-by-step explanation:
To solve this equation easily, we graph each equation in a graphing calculator and see which of them doesn't intercept the x-axis.
The correct answer is option
D
f(x) = - 5^(x-5) - 1
so first we should make the denominators the same so find a multiple that 5 and 8 share: they share a multiple of 40, so whatever you do to the denominator you do to the numerator. So the equation should now look like 16/40+15/40 and the answer is 31/40!!
