The system of equations y = 2x + 5 and y = –3x – 15 is shown on the graph below. On a coordinate plane, 2 lines intersect at (negative 4, negative 3).

According to the graph, what is the solution to this system of equations?
(–4, –3)
(–3, –4)
(–5, 5)
(5, –5)

If a company produces x units of an item at a cost of $35 apiece the function c=35x is a of the total production costs

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.

D. in a discrete probability distribution, the sum of the probabilities for the discrete variables will be > 1. true or false
