Step-by-step explanation:
For a line to be perpendicular to another line, its slope must be the negative inverse of the original line’s.
For example, the negative inverse of 3x is -1/3 x.
The line y = 3x is perpendicular to y = -1/3 x. Any line with a slope of 3x is perpendicular regardless of its y-intercept.
Plotted on the graph are the equations:
Y = 3x
Y = 3x + 3
Y = - 1/3 x
As you can see, the lines with the slope of 3x are perpendicular to the third line regardless of their y-intercepts. Only slope matters in regards to parallel and perpendicular lines.
Answer:
x=3/2
Step-by-step explanation:
There is only one solution.
Answer:
A.) y = 20x
B.) 21 minutes
Step-by-step explanation:
y = mx + b; y2 - y1/ x2 - x1 = m (slope)
A.) If a factory can build 20 cars per hour, the first point would be (1, 20). To find the slope (m), divide the y-axis by the x-axis: 20/1 = 20.
B.) Before we can do this problem, we must first convert the hours to minutes. 1 hour = 60 minutes. Then we divide the minutes by the number of cars. 60 ÷ 20 = 3. That means the factory builds 1 car every 3 minutes. Multiply the number of cars, 7, by the number of minutes it takes to make one car: 7 • 3 = 21.

Answer:
3/7 is equal to 12/28
Step-by-step explanation:
n equals 12 because 28 divided by 7 is 4. multiply 3 by 4 and get 12.
