Answer:
66 and 67 are the answers
Answer:
n = 4 or n = -4
Step-by-step explanation:
We have: 4n² - 3 = 61.
Add 3 to both sides:
4n² = 61 + 3 = 64
Divide both sides by 4:
n² = 64/4 = 16
Square root both sides:
n = +/- √16
n = 4 or n = -4
The answers are 4 and -4.
The general form of a linear equation is
y = mx + b
where m = slope and b = y-intercept
Here m = 2/7
To get to its perpendicular equation, first the slope should be negative reciprocal. So the perpendicular slope is m = -7/2
Given the point (-2,3), use the point-slope form equation, that is
y - y1 = m(x - x1)
Plug in
y - 3 = (-7/2)[x - (-2)]
y - 3 = (-7/2)x - 7
y = (-7/2)x - 7 + 3
y = (-7/2)x - 4
That is the equation required.
Domain is the input and/or x
Range is the output and/or y
So to find the domain you would look for the x axis in a graphed function, the input on a table, or the numbers in a problem that would be on that axis or side of the table. Same for range
