Answer:

x = 4

Step-by-step explanation:

Square both sides

x+5 = 25-10sqrt(x)+x

20 = 10sqrt(x)

sqrt(x) = 2

Square both sides again

x=4

Verify sol

x = 4

Start by squaring the numbers on both sides to get rid of the square root on both the left and right sides to get:

x + 5 = 5^2 – x

x + 5 = 25 – x

Then rearrange to make x the subject.

x + 5 = 25 – x

2x + 5 = 25

2x = 20

x = 10

How are the two angles below related? Drawing not to scale.<br><br><br> Drawing is not to scale.
Phoenix [80]

we know that

Two angles are supplementary if their sum is equal to 180 degrees

in this problem we have

Angle\ 1=45\°

Angle\ 2=135\°

so

Angle\ 1+Angle\ 2=180\°

therefore

<u>the answer is</u>

Question 7 of 10
sergejj [24]

The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

<h3>What is the matrix about?</h3>

Looking at the product of matrix, note that to multiply  the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.

And in this case (propensity), it is not satisfied by the first  option because:

C =  3 x 1  and

O= 2 x 1  matrix

In this case CD is therefore undefined.

So we can say that The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

The |6f|= -2 I don't understand what to do
aleksandr82 [10.1K]
First you are going to solve for f. 

6f = -2 

you must get f alone so you divide both sides of the equation by 6 which becomes ....


f = -3


now you add the absolute value sign to -3. absolute value is how far away your answer is from 0. -3 is 3 away from zero so f = 3

Complete the input-output table for linear function y=3x
Veseljchak [2.6K]

The input and output table for the linear function y = 3x is (-2, -6), (-1, -3), (0, 0), (1, 3) and (2, 6).

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the linear function y = 3x:

When x = -2; y = 3(-2) = -6

When x = -1; y = 3(-1) = -3

When x = 0; y = 3(0) = 0

When x = 1; y = 3(1) = 3

When x = 2; y = 3(2) = 6

The input and output table for the linear function y = 3x is (-2, -6), (-1, -3), (0, 0), (1, 3) and (2, 6).
