Answer:
Step-by-step explanation:
example :
2 1/4 + 3 1/2
you can either turn them to improper fractions, find the common denominator, and then add them and then convert that answer to a mixed number
2 1/4 + 3 1/2 = 9/4 + 7/2 = 9/4 + 14/4 = 23/4 = 5 3/4
OR
separate them....add the whole numbers, then the fractions
2 1/4 + 3 1/2 .......2 + 3 = 5.....1/4 + 1/2 = 1/4 + 2/4 = 3/4.....now put them back together and u get : 5 3/4
17.30 *19 = 328.70 per week
4000 / 328.70 = 12.17 weeks
so it would take her 13 weeks
answer is B 13weeks
Avani wrote the linear equation y = 5x + 4. Then, she wrote the equation of the line that is perpendicular to y = 5x+ 4 and that passes through (15,–2). If her new equation is in the form
, what is the value of b?

- m is the slope
- b is the y-intercept
The equation of a line that is perpendicular to another line always has the opposite reciprocal slope. In the original equation, the slope is 5. The opposite of 5, which refers to the sign, is -5. The reciprocal of -5 is -1/5. That means the slope of the new line is -1/5.
The perpendicular line:
- Has a slope of

- Passes through the point (15, -2)
To find the equation of a line that passes through a specific point, you need to use slope-intercept form.

- y₁ is the y-value of the point
- m is the slope
- x₁ is the x-value of the point
y₁ is -2, m is -1/5, and x₁ is 15.
Substitute the known values into the equation:

Open the parentheses and distribute:

The new equation will be:

Lastly, you need to move the positive 2 to the other side to keep it in y = mx + b form.

The equation of the perpendicular line is:

The value of b is 1.
