Answer: (28/37) - (48/37)*i
Step-by-step explanation:
We want to solve the quotient:
To solve it, we need to multiply the whole quotient by the complex conjugate of the denominator.
Remember that for a complex number:
a + b*i
the complex conjugate is:
a - b*i
Then if the denominatoris:
6 + i
the complex conjugate is:
6 - i
Then to solve the quotient we have:
This is equal to:
Then the initial quotient is equal to:
(28/37) - (48/37)*i
slope intercept form:
y = mx + b
m = slope
b = y-intercept
the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.
y = mx + 4
the slope is technically the rate of change (rise over run) bewteen points.
If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1
y = 1x +4
this could also be:
y = x + 4
(because the 1 is invisible but still there)

Answer:
<u>B. 4x ≤ 320</u> is the correct option.
Step-by-step explanation:
Have a nice day!
Answer:
A. (0, 60)
B. 15x
Step-by-step explanation:
The initial value is the same as the y-intercept, which is 60 or (0, 60).
The rate of change would be the same as the slope. To find the slope, you do rise/run. You move 15 units up, and 1 to the right. That would be 15x.
Hope this helps!
