Find x in the equation: 2x + 9 = 5x - 12

Answers

Answer:

x = 7

Step-by-step explanation:

Add 12 to both sides:

2x + 9 = 5x - 12

2x + 21 = 5x

Subtract 2x from both sides:

21 = 3x

Divide each side by 3:

7 = x

So, x = 7

If you are trying to decide whether a system of equations has a solution, would you rather have the equations or the graphs? Why?

Answers

Answer: Graphing

Step-by-step explanation:

Graphing is the best method to use when introducing a new student to solving systems of two equations in two variables, because it gives them a visual to recognize what they are looking for. Graphing is less exact and often takes more time than the other methods.

* Hopefully this helps!

At the time when we have to decide whether the system of equations has a solution so here we do the graphing.

Usage of graphing:

It is considered to be the best method at the time when it introduced to the new student for solving the system of 2 equations  in 2 variables as it provides the visual to record what actually they have looking.

Also, graphing is considered to be less exact and taken more time as compared to the other methods.

It is a right triangle. The distance is the hypotenuse of the triangle.

Use the Pythagorean theorem:

Distance = sqrt(3^2 + 2^2)

What is the measure of arc S T?

56°
68°
112°
163° (it is 56!)

Answers

Answer:

Answer: 112°

Step-by-step explanation:

Angles in a Circle

An inscribed angle is formed between two chords whose vertices lie on the circumference of a circle. The figure shows three chords: TU, SU, and ST. SU happens to also be a diameter because it goes through the center of the circle V.

ST and SU form an inscribed angle of 34°. The corresponding central angle is TVU and its measure is

[tex]m\angle TVU=2*34^\circ=68^\circ[/tex]

The required measure of the arc ST is the measure of the angle SVT. Note that SVT and TVU are complementary, thus:

[tex]m\angle TVU+m\angle SVT=180^\circ[/tex]

Solving for the measure of SVT:

[tex]m\angle SVT=180^\circ-m\angle TVU[/tex]

[tex]m\angle SVT=180^\circ-68^\circ=112^\circ[/tex]

D sounds like the most probable choice.

The solution of the inequality is x≥-13 and the graph c represents the inequality, option c is correct.

The given inequality is -1/4(12x+8)≤-2x+11.

Let us solve for x:

Apply distributive property:

-3x-2≤-2x+11

Add 2 on both sides of the inequality:

-3x+2x≤11+2

Combine the like terms:

-x≤13

x≥-13

Hence, the graph of c represents the solution of the inequality.
