Answer:

Step-by-step explanation:
The slope intercept form of a line is given as:
y = mx + c
Where m is the slope and c is the y-intercept
Let's rearrange the equation given in this form:
2x - 5y = -11
5y = 2x + 11
y = 2/5 x + 11/5
So the slope is 2/5
Slope of line that is perpendicular to this is the "negative reciprocal" of this slope. Which means the slope of perpendicular line would be -5/2
Thus, equation would become: y = -5/2x + c
Now we need to find c. For this we plug in 7 into x and 5 into y and solve for c [(7,5) is the point given]. Thus,

Thus, the equation of perpendicular line is:

Answer:
Step-by-step explanation:
If a store is having a 20% off sale
By buying an item you save 20% of the price
If Mai saves $13 on an item she is also saving 20%
$13 = 20% of the price
$65 = 100% of the original price
$65 is your answer!
Expressions can be read as how many times you're multiplying a number by itself.
(1/2)^4 can be rewriten as (1/2)*(1/2)*(1/2)*(1/2), which simplifies to 1/16
Step-by-step explanation:
6 - 4a < 2
6 - 2 < 4a
4 < 4a
1 < a
6 - a > 2
6 - 2 > a
4 > a
3a - 1 < 8
3a < 8 + 1
3a < 9
a < 3
