Answer:
Slope of given line = 
and slope of perpendicular line = 
Step-by-step explanation:
We are given a line -9x - 4y = 5 .
We have to find the slope of a line parallel to this line and also a line perpendicular to this line.
Let the general equation be ax + by = c.
Then the slope of this line = 
=
The slope of a line perpendicular to a line is the negative inverse of the slope of the line. Using this concept,
Slope of line perpendicular to the given line = 
=
Answer:
26 y + 5
Step-by-step explanation:
Simplify the following:
7 3 y + 4 3 y - 3 y - 2 2 y + 5
7×3 = 21:
21 y + 4 3 y - 3 y - 2 2 y + 5
-2×2 = -4:
21 y + 4 3 y - 3 y + -4 y + 5
4×3 = 12:
21 y + 12 y - 3 y - 4 y + 5
Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:
(21 y - 4 y + 12 y - 3 y) + 5
21 y - 4 y + 12 y - 3 y = 26 y:
Answer: 26 y + 5
Answer:c
Step-by-step explanation:
Answer:
The slope is 35 and it means the technician earns $35 per hour.
Step-by-step explanation:
The technician finds that
- when he works 55 hours during the month, he earns $2,125;
- when he works 30 hours, he earns $1,250.
Let
x = number of hours worked
y = amount of money earned
Find the slope of the linear equation:
Equation of the linear function:
The slope is 35 and it means the technician earns $35 per hour.
