Answer:
m =
Step-by-step explanation:
We need to find the slope of this equation to find the slope of a line perpendicular to it. This means we must solve for y.
Start off by subtracting 8x from both sides of the equation to start isolating the variable y.
Now solve for y by dividing both sides of the equation by -7.
This can be broken into two parts by distributing the negative sign from the -7 into the 9 and -8x like so:
The slope of a line is the coefficient of x, so in this case the slope of the given line () is .
Two lines that are perpendicular would have opposite reciprocal slopes, which means the perpendicular slope would be the negative counterpart and would be flipped.
For example, if you have 2 as the slope of one of the perpendicular lines, the other line would be the opposite (-2) reciprocal ().
Therefore, since we have the slope of one of the perpendicular lines (the given line), we would find the opposite reciprocal of it's slope to solve this problem.
Slope:
The slope of the line perpendicular to is .
18x = 900
How many students went on the trip?
Answer:
50
Step-by-step explanation:
18x=900
divide 900 by 18 and you get x which equals 50
you can check your answer by multiplying 18x50=900
Answer:
No ratios do not form a proportion.

For example you take these fractions 9/4 and 2/?
9 - 2
4 - ?
Solve: 4×2÷9= about 0.9
0.9≠ 3
6, -24, 96, -384,...
Answer:
see explanation
Step-by-step explanation:
The recursive formula allows us to calculate the next term in the sequence from the previous term.
The common ratio r = = - 4
Thus multiplying any term by - 4 gives the next term, that is
= - 4 with a₁ = 6
