Answer:

1 :

Step 2 :

Equations which are never true :

2.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : 2x+1 = 0

Subtract 1 from both sides of the equation :

2x = -1

Divide both sides of the equation by 2:

x = -1/2 = -0.500

One solution was found :

x = -1/2 = -0.500

Question 4 <br> Use the figure below to find the value of x and y

Tpy6a [65]

Answer:

$x=4, y=8$

Step-by-step explanation:

step 1

Find the value of y

we know that

In the right triangle of the figure

$cos(30\°)=\frac{4\sqrt{3}}{y}$

Remember that

$cos(30\°)=\frac{\sqrt{3}}{2}$

$\frac{\sqrt{3}}{2}=\frac{4\sqrt{3}}{y}$

Simplify

$y=8\ units$

step 2

Find the value of x

In the right triangle of the figure

$sin(30\°)=\frac{x}{8}$

Remember that

$sin(30\°)=\frac{1}{2}$

$\frac{1}{2}=\frac{x}{8}$

$x=4\ units$

Select the graph of the solution. Click until the correct graph appears. 3x + 1 < 7 (line graph)

WARRIOR [948]

3x + 1 < 7...subtract 1 from both sides
3x < 7 - 1
3x < 6 ...divide both sides by 3
x < 6/3
x < 2

there will be an open circle on 2....because the problem has no equal sign...the line will be shaded to the left...because it is less then.
