D. Since you bought 3 text books you will have to multiply and then add the rest of the numbers
The answer would be (-3+18) + (i +5i)
This is because changing the order of the numbers does not change the sum
A. y-intercept
B. The slope is 3/4, the y-intercept is 0
C. For this one you need to put it in y-intercept form. So, you subtract 2x, and move it over to 12. The equation would look like 6y = 2x + 12.
Then, divide everything by 6, and the equation would look like: y = 2/6x + 2
Thus, the slope is 2/6x and 2 is the y-intercept.
Adds 4 each time and 5-4=1 so nth term is 4n + 1
Answer:

Step-by-step explanation:
Let x = unknown number


Multiply both sides by 9:

Expand brackets:

Add 32 to both sides:

Divide both sides by 8:
