Answer:
dom: (-∞,∞)
dom: (–∞,–2)u(–2,∞)
Step-by-step explanation:
*distribute the negative sign into (x+2)!
a parabola (anything that begins with ) will have a domain of (-∞,∞) or all real numbers!!
use synthetic division to divide (the attached picture)
domain: Because the graph is not continuous, you have to write the domains on both sides of the asymptote which is (-∞,-2)u(-2,∞)
<u>synthetic division:</u>
1. take the divisor (x+2) and solve for x. x= –2 this goes in the top left corner
2. write the numbers AND their signs on the top row. if there is no number and just the variable (like ) just write 1.
3. the first number gets pulled down
4. multiply -2 by 1 and subtract it from –5. (-5-2= -7)
multiply -2 by -7 and add that to the next number in the top row which is -7. (-7 + 14=7)
5. the first number in the bottom row of numbers is the first number in the answer but with one less exponent than the dividend. **write 1 as x**
6. the last number in the bottom row, if it is not 0, is a remainder. write it as that number over the divisor. in this case the remainder is 7. so write it as
Answer:
The equation of line is given as
Step-by-step explanation:
Point on the line given :
We can find the slope of the line first from the given points.
Slope= Undefined.
The slope of the line is undefined which means that the line is parallel to y-axis.
From the points known to us we can tell that the line passes through
∴ The equation of line is given as

Food = 1/4
gasoline = 3/5
Total = 1/4 + 3/5 = 17/20
17/20 = 272
1/20 = 272 ÷ 17 = 16
20/20 = 16 x 20 = $320
