Answer:
15(n-1)-45
Step-by-step explanation:
Increases by 15, so sequence is arithmetic, and goes to positive.
1st term is -45
so 15(n-1) gives us first term.

B. 5r3 − 4r2 + 14r − 16
C. 5r3 − 6r − 16
D. 5r3 + 10r − 16
The product is: 5r³ -34r² + 44r -16
An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)
Given:
(5r − 4)(r² − 6r + 4)
= 5r*r² - 5r *6r + 5r * 4 - 4r²+ 24r -16
= 5r³ - 30r² + 20r -4r² + 24r - 16
= 5r³ -34r² + 44r -16

Step-by-step explanation:
find two points on the line are exact on the grid,
the one (4, -10),
the another (-1,5),
then the slope is:
(-10-5)/(4-(-1))
=-15/5
