HELP Find the value of two numbers if their sum is 5 and their difference is 30

vodomira [7]

Answer:

The 2 numbers are -12.5 and 17.5.

Step-by-step explanation:

Let 1 number be x then x - y = 30 where the other number is y.

y = x - 30 so the sum is:

x - 30 + x = 5

2x = 35

x = 17.5

and y = 17.5 - 30 = -12.5.

Solve for x & y. 30x−42y=−6 and 5x−7y=−1

vladimir1956 [14]

Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:

$\frac{30x - 42y}{6} = \frac{-6}{6} \\ 5x - 7y = -1$

That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.

For example, $x = 0$ and $y = \frac{1}{7}$ would work, but so would $x = 1$ and $y = \frac{6}{7}$

I need help with someone explaining how to find the range of this! This course didn’t explain anything!

zaharov [31]

Answer:

$(-infinity,3)$ , D

Step-by-step explanation:

3 if x is greater than or equal to 1 is nothing. That leaves us with $h(x)=2x+1$ if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is $(-infinity,3)$ , which is D.
