Answer:
2^36 3^48 is the correct answer
C because it simplifies to 0=0 which proves that it has infinite solutions!
Answer:
$2.72
Step-by-step explanation:
The increase from last week is the fraction ...
(new price)/(old price) -1 = (1.82/1.65) -1 = 17/165
so the amount of increase Sally will pay this week is ...
17/165×$26.40 = $2.72

<em>Comment on the working</em>
We could work this several ways. Perhaps most straightforward would be to determine how many gallons Sally bought last week, and multiply that by the change in price. Or, the number of gallons could be multiplied by the new price per gallon and the difference from the old purchase amount found.
If you look at the numbers, you see that we have effectively done it the first way. The change in price is $0.17 per gallon, and the number of gallons Sally bought is $26.40/$1.65.
Answer:
x= the second one I hope I helped
a. Equation in slope-intercept form of a line parallel to y = 2/5x +1 will be: y = 2/5x + 5
b. Equation in slope-intercept form of a line perpendicular to y = 2/5x +1 will be: y = -5/2x + 1
c. Equation in slope-intercept form of a line that is neither parallel nor perpendicular to y = 2/5x +1 will be: y = 3x + 1
<h3>Slope-intercept Equation of Parallel and Perpendicular Lines</h3>
- Slope-intercept equation, where b is the y-intercept and b m is the slope is represented as y = mx + b.
- Equations of parallel lines have the same slope.
- Equations of perpendicular lines will have slope that are negative reciprocal of each other.
- If two lines are neither parallel nor perpendicular, their equation will have different slopes, and the slope of one is not the negative reciprocal of each other.
Therefore:
a. Equation in slope-intercept form of a line parallel to y = 2/5x +1 will be: y = 2/5x + 5
b. Equation in slope-intercept form of a line perpendicular to y = 2/5x +1 will be: y = -5/2x + 1
c. Equation in slope-intercept form of a line that is neither parallel nor perpendicular to y = 2/5x +1 will be: y = 3x + 1
