What two numbers can be multiplied to be -150 and added to be 5
Answers
x + y = 5
x + y = 5
x - x + y = -x + 5
y = -x + 5
xy = -150
x(-x + 5) = -150
x(-x) + x(5) = -150
-x² + 5x = -150
-x² + 5x + 150 = 0
-1(x²) - 1(-5x) - 1(-150) = 0
-1(x² - 5x - 150) = 0
-1 -1
x² - 5x - 150 = 0
x = -(-5) ± √((-5)² - 4(1)(-150))
2(1)
x = 5 ± √(25 + 600)
2
x = 5 ± √(625)
2
x = 5 ± 25
2
x = 2.5 ± 12.5
x = 2.5 + 12.5 or x = 2.5 - 12.5
x = 15 or x = -10
x + y = 5
15 + y = 5
- 15 - 15
y = -10
(x, y) = (15, -10)
or
x + y = 5
-10 + y = 5
+ 10 + 10
y = 15
(x, y) = (-10, 15)
The two numbers that add up to 5 and multiply to -150 are 15 and -10.

An equation for c, in terms of m is given by: c = 3m + 45.
What is equation?
A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 = 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others.
Given that:
Initial charge of rent = $45
Let, the additional fee per mile driven is $x.
Taylor were to drive 5 miles, the total cost would be $60.
Hence,
60 = 45 + 5x
5x = 60 -45
5x = 15
x = 15/5
x = 3.
the additional fee per mile driven is $3.
Now, if c = total rent and m is how many miles to drive, the equation joining them be:
c = 3m + 45
This is the equation for c, in terms of m.

The equation for the total cost (C) in terms of the number of miles driven (m) is C = $45 + $3m.
How to write an equation representing a situation?
Taylor is charged an initial fee of $45 and an additional fee per mile driven. Let's denote the additional fee per mile as 'x' (in dollars per mile).
So, the equation for the total cost C can be written as:
C = $45 (initial charge) + x (fee per mile) * m (number of miles driven)
Given that when Taylor drives 5 miles, the total cost is $60, you can substitute these values into the equation:
$60 = $45 + x * 5
Now, you can solve for x:
x * 5 = $60 - $45
x * 5 = $15
x = $15 / 5
x = $3 per mile
Now that you know the additional fee per mile is $3, you can write the equation for the total cost C in terms of m:
C = $45 + $3m

A.
No, it is not reasonable because –5 + –8 = –13.
B.
Yes, it is reasonable because –5 + –8 = +13.
C.
No, it is not reasonable because if you add two numbers you will get a number that is greater than either of the two numbers.
