Step-by-step explanation:

Multiply part of the right side by - 4

2x = -4*1/4 + 4* 3x/4  + 4                             Combine

2x = - 1 + 3x + 4                                            Combine again

2x = 3 + 3x                                                    Subtract 3x both sides

2x - 3x = 3                                                     Combine

The value of y given the inverse relationship is 5.

If two variables vary inversely, as one variable increases, the other decreases in value.

The equation that is used to represent inverse relationship is:

y = k/x

Where k is the constant of proportionality

k = yx

k = 4 x 15 = 60

y = 60 / 12

y = 5

Step-by-step explanation:

Answer: y = -12

Equation's:

Solve them simultaneously:

4x - 28 = 1.5x - 18

4x - 1.5x = -18 + 28

2.5x = 10

x = 10/2.5 = 4

Now find the value of y:

y = 4x - 28

insert x = 4

y = 4(4) - 28

y = 16 - 28 = -12

Answer:

[tex]y=-12[/tex]

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y = 4x - 28\\y = 1.5x - 18\end{cases}[/tex]

Use the method of substitution to solve for x:

[tex]\begin{aligned}y & = y\\\implies 4x-28 & = 1.5x - 18\\4x-1.5x & = -18+28\\2.5x & = 10\\x & = 10 \div 2.5\\x & = 4\end{aligned}[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\begin{aligned} y & = 4x-28\\\implies y & =4(4)-28\\y & = 16-28\\y & = -12\end{aligned}[/tex]

Answer:

D(x=1).

Step-by-step explanation:

2(5x+8)=6x+20

10x+16=6x+20

10-6x+16=6x-6x+20

4x+16=20

4x+16-16=20-16

4x=4

4x/4=4/4

x=1

The solution to this equation is x = 1

Given the equation, we apply the distributive property.

2( 5x + 8 ) = 6x + 20

10x + 16 = 6x + 20

10x - 6x = 20 - 16

4x = 4

x = 4 ÷ 4

x = 1

Therefore, the value of this equation is x = 1

Answer:

Angles of the isosceles triangle are 36°, 72° , 72°

Step-by-step explanation:

Vertex angle : Base angle = 1 : 2

Vertex angle = x

Base angle = 2x

Sum of all angles of a triangle = 180°

          x + 2x + 2x = 180°

                      5x = 180

                        x = 180 ÷ 5

                        x = 36°

2x = 2 *36 = 72°

Angles of the isosceles triangle are 36°, 72° , 72°

The x-intercept and y-intercept of the equation: 3x - y = -9 is -3 and 9 respectively.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have equation:

3x - y = -9

The above equation represents a linear equation;

The equation can be written as:

y = 3x + 9

To find the x-intercept plug y = 0

x = -3

To find the y-intercept plug x = 0

y = 9

Thus, the x-intercept and y-intercept of the equation: 3x - y = -9 is -3 and 9 respectively.

Answer:

y = 5x + 2

Step-by-step explanation:

slope intercept form is y = mx+ b

the y- intercept is 0,2 so 2 is your b.

for m you do rise over run aka y/x. for every 5 rise up the x runs one so your slope(m) = 5

 so y=5x+2
