From the second equation:-
x = 6 - 4y
Substitute this for x in the top equation
Answer:
1000 times greater.
Step-by-step explanation:
10^9 / 10*6
= 10^(9-6)
= 10^3
= 1000.
Given that the debt has been represented by the function:
f(x)=-6x^2+8x+50
To get the number of years, x that it would take for the company to be debt free we proceed as follows:
we solve the equation for f(x)=0
hence:
0=-6x^2+8x+50
solving for x using the quadratic formula we get:
x=[-b+/-sqrt(b^2-4ac)]/2a
x=[-8+/-sqrt(8^2-4*(-6)*50)]/(-6*2)
x=[-8+/-√1264]/(-12)
x=27.552
x~28
Answer:
The options 2x² + x² + x = 30 and 9x + 3x² = 14 + x + 1, and -x² + 4x + 7 = - x² - 9
Step-by-step explanation:
After being rearranged and simplified, which of the following equations could be solved using the quadratic formula?
The answers are:
2x² + x² + x = 30
9x + 3x² = 14 + x + 1
-x² + 4x + 7 = - x² - 9
