What is y-13x=9 and how did you solve it

Mathematics

AURORKA [14]3 years ago
4 0

Simplifying

y + -13x = 9

Reorder the terms:

-13x + y = 9

Solving

-13x + y = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

-13x + y + -1y = 9 + -1y

Combine like terms: y + -1y = 0

-13x + 0 = 9 + -1y

-13x = 9 + -1y

Divide each side by '-13'.

x = -0.6923076923 + 0.07692307692y

Simplifying

x = -0.6923076923 + 0.07692307692y

Answer:

A

Step-by-step explanation:

To sovle this we must combine the numbers togther and the variables togther.

We have:

8c+6-3c-2

Lets take out the c's and combine them:

8c -3c

=

5c

Now lets take out the numbers:

6-2

=

4

Now lets put these back together and we get the expression:

5c+4

This looks like A.

Hope this helps! :D

Suppose that $f(x)$ and $g(x)$ are functions on $\mathbb{r}$ such that the range of $f$ is $[-5,3]$, and the range of $g$ is $[-
grigory [225]

The largest possible value of b is 10, since for some x = x₀ it could be the case that f(x₀) = -5 and g(x₀) = -2; then f(x₀) g(x₀) = -5 × -2 = 10.
