Using a system of equations, the numbers that add to 1 and multiply to -72 are given as follows:
9 and -8.
<h3>What is a system of equations?</h3>
A system of equations is a set of equations involving multiple variables that are related, and then operations are made to solve these equations and identify the numeric value of each variable.
In the context of this problem, the two numbers are the variables. They are unknown, hence they are going to be defined as follows:
x and y.
They add to 1, hence:
x + y = 1.
They multiply to -72, hence:
xy = -72.
From the first equation, we have the following relation:
y = 1 - x.
Replacing in the second, we have that:
x(1 - x) = -72.
x - x² = -72.
x² - x - 72 = 0.
The quadratic function can be factored as follows:
(x - 9)(x + 8) = 0.
Hence the amounts are given as follows:
Which are the two numbers representing the solution to the system of equations.

Answer:
Zero
Step-by-step explanation:
The line is parallel to x-axis. So, the slope is 'zero'
It will take 4 minutes to rotate 1º because 15 divided by 15 is one (to get 1º) and 60 (1 hour) divided by 15 is 4.
