Help i dont remember dis stuff from last year

See below for the solution to the systems of equations

<h3>How to solve the systems of equations?</h3>

<u>System of equations 1</u>

Here, we have

3x - 4y = -16

3x + 4y = 8

We start by plotting the graph of both equations

Next, we write out the point of intersection of the equations

See attachment for the equation of the system

From the attached graph, the point of intersection of the equations is (-4/3, 3)

Hence, the solution to the system is (-4/3, 3)

<u>System of equations 2</u>

Here, we have

-x = - 6 + 2y

-18 + 6y = -3x

We start by plotting the graph of both equations

Next, we write out the point of intersection of the equations

See attachment for the equation of the system

From the attached graph, both lines are on each other

This means that the system of equations have infinite many solutions

A report card shows that a student earns 21 21 points on a test with a total of 25 25 points. What percentage of the total point

Ostrovityanka [42]

When a report card shows that a student has earned 21 points on a test with a total of 25 points, it can be concluded to state that the student has secured 84 percentage of the total points of the test.

The computation of the percentage of points secured by the student out of the total available points in a test can be done using the generalized formula and the use of provided information into the same as below,

Percentage = Scored Secured / Total Points x 100

Percentage = 21 / 25 × 100

Percentage = 0.84 × 100

Percentage = 84 percentage.

Therefore, the student has earned 84 percentage of total points on a test.

F(x)=2x+1 and g(x)=x^2-7, find (f g) (x)

hodyreva [135]

The answer is (f o g)(x) = 2x^2 - 13

In order to find a composite function, you take the first letter (in this case f) and use that equation. You then remove the variable and put in the second letter (g).

f(x) = 2x + 1 ----> Remove variable.

f(x) = 2( ) + 1 ----> Insert g(x)

(f o g)(x) = 2(x^2 - 7) + 1 ----> Distribute

(f o g)(x) = 2x^2 - 14 + 1 ----> Simplify

(f o g)(x) = 2x^2 - 13

The path a character takes to navigate a level of a video game is given in the following graph.

KonstantinChe [14]

We want to find the domain for the graphed function. We will see that the correct option is A: -12 ≤ x ≤ 14

<h3>What is the domain of a function?</h3>

For a function f(x) we define the domain as the set of possible inputs that we can use in the function.

In this case, we need to see the values in the horizontal axis that the graph covers.

We can see that it goes from -12 to 14. We also can see that there are two jumps, at x = -6 and at x = 8, but these values belong to the graph (denoted by the black dot) meaning that these are in the domain.

Then the domain is:

-12 ≤ x ≤ 14
