I have a maths problem : Simplify x+x+y x y I’m not sure how to work it out! Please help!

maks197457 [2]

Answer:

$2x+y^2$

Step-by-step explanation:

For this, you check to see if any of these variables are the same. There are two x's, and 2 y's. So, you have to multiply x and x, which gives you 2x, and since you multiply the y's it will give you y^2.

So the answer will be $2x+y^2$

Which function has an inverse function?

daser333 [38]

Answer: Option B

Step-by-step explanation:

By definition, only those functions that are one to one have an inverse function.

A function is one by one if there are not two different input values, $x_1$ and $x_2$ , that have the same output value y

Note that the function $f(x)= \frac{|x+3|}{5}$ is not a one-to-one function

When x=2 $f(x)= \frac{|2+3|}{5}=1\ ,\ \ y=1$

When x=8 $f(x)= \frac{|-8+3|}{5}=1\ \ ,\ y=1$

Note that the function $f(x)= \frac{x^4}{7}+ 27$ is not a one-to-one function

When x=1 $f(x)= \frac{(1)^4}{7}+27\ ,\ \ y=\frac{190}{7}$

When x=-1 $f(x)= \frac{(-1)^4}{7}+27\ ,\ \ y=\frac{190}{7}$

Note that the function $f(x)= \frac{1}{x^2}$ is not a one-to-one function

When x=1 $f(x)= \frac{1}{(1)^2}\ ,\ \ y=1$

When x=-1 $f(x)= \frac{1}{(-1)^2}\ ,\ \ y=1$

Then the answer is the option B.

You can verify that The function $f (x) = x ^ 5-3$ is a one-to-one function and therefore its inverse is a function

If m<1=70 degrees and <1 and <2 are supplementary angles . Find m<2

maksim [4K]

Supplementary angles are angles that add up to 180º.
If m∠1 is 70º, then m∠2 must be an angle that can be added to 70º to equal 180º.
In other words, m∠1 + m∠2 = 180º.

Since m∠1 is 70º, we can plug this value in the equation.
70º + m∠2 = 180º

To solve, just subtract 70 from both sides, which means 180 - 70 = m∠2.
180 - 70 = 110
m∠2 = 110

The measure of m∠2 is 110º.

Hope this helps!
