Answer:
system of equations
Step-by-step explanation:
You can eliminate one of the variable terms in a <u>system of equations</u> by adding or subtracting another equation.
To find this out, use a percent proportion, use cross products, and solve the equation.
So, the percent tip is 14%.
X=-8,3.
divide all terms by the two in the first term to get x^2+5x-24=0. Then find the factors. To do so, find what two numbers can be multiplied to get 24, and whether those two numbers can be added or subtracted to get the middle term (5). Since 8x(-3)=24 and 8-3=5, (x+8) and (x-3) are the factors. Then set the factors equal to zero. Add or subtract these numbers to the other side of the equation and you then get x=-8,3. These are the roots.
