That’s 6/100 mate good lyck
Answer:
D.
Step-by-step explanation:
First set everything to 0.

Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
4x/15 = 60/x
4x^2 = 900
x^2 = 225
x = 15
The slope of function A is the coefficient of x, which is 6.
The slope of function B is the rise divided by the run, which is 3/1 = 3.
The appropriate choice is ...
... c) Slope of Function A = 2×Slope of Function B
