Answer:

H

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 2y = 19 ( subtract 3x from both sides )

2y = - 3x + 19 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{19}{2}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{3}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex] → H

Answer:

m=-1/4

Step-by-step explanation:

Perpendicular lines are negative reciprocals.

So if you have a slope of m= 4x you can break it up into, two parts

                         m= -4x

this is the negative^

and the reciprocal of m= -4x is m= -1/4x

The slope of the green line if the lines are perpendicular would be -1/4.

If two lines are perpendicular to each other, then their slopes are negative reciprocal of each other.

That means, if one line's slope is 'a', then its perpendicular line's slope would be -1/a.

Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

For the two lines two be perpendicular, the product of their slope must be -1.

Let the slope of the red and green line be m1 and m2.

Given the following

The Slope of red line = 4

According the definition, we get,

4m2 = -1

m2 = -1/4

Hence, the slope of the green line if the lines are perpendicular is -1/4

Answer:

14 - 8i

Step-by-step explanation:

The simplified expression is 14 - 8i.

Given is an expression (2 - 3i)(4 + 2i), we need to simplify it,

To simplify the expression (2 - 3i)(4 + 2i), we can use the FOIL method, which stands for First, Outer, Inner, Last.

First, we multiply the first terms of each binomial:

2 x 4 = 8.

Outer, we multiply the outer terms of each binomial:

2 x 2i = 4i.

Inner, we multiply the inner terms of each binomial:

-3i x 4 = -12i.

Last, we multiply the last terms of each binomial:

-3i x 2i = -6i².

Now, simplify the expression:

8 + 4i - 12i - 6i².

Since i² is defined as -1, we can substitute it:

8 + 4i - 12i - 6(-1).

Simplify further:

8 + 4i - 12i + 6.

Combine like terms:

14 - 8i.

Therefore, the simplified expression is 14 - 8i.

Answer:

Step-by-step explanation:

Answer:

33 degrees

Step-by-step explanation:

Supplementary angles add up to 180 degrees. So take (4x)+(x+15)=180. Simplify this to 5x+15=180, move 15 to the right by subtracting. 5x=180-15, 5x= 165. Now divide by 5, x=165/5, which is x= 33 degrees.

x=[tex]\sqrt{6}[/tex]

Step-by-step explanation:

subtarct 2 t the other side

2x^2=12

now divide 2 to 12

x^2= 6

now square root both sides

x=[tex]\sqrt{6}[/tex]

thats the answer!

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x²+2=14

Step 2: Subtract 2 from both sides.

2x²+2 −2  =14 −2

2x²=12

Step 3: Divide both sides by 2.

2x²÷ 2  =12 ÷ ²

x²= 6

Step 4: Take square root.

x= √ 6

[tex]T = 100[/tex]

Step-by-step explanation:

See attachment for parallelogram TRIK

Given

[tex]T = 5x[/tex]

[tex]I = 2(x + 30)[/tex]

Required

Determine T

Because T and I are opposite angles of the parallelogram, then they are congruent.

i.e.

[tex]T = I[/tex]

Substitute values for T and I

[tex]5x = 2(x + 30)[/tex]

Open bracket

[tex]5x = 2x + 60[/tex]

Collect Like Terms

[tex]5x - 2x = 60[/tex]

[tex]3x = 60[/tex]

Solve for x

[tex]x = \frac{60}{3}[/tex]

[tex]x =20[/tex]

Recall that:

[tex]T = 5x[/tex]

[tex]T = 5 * 20[/tex]

Answer: [tex]167\dfrac15\text{ miles}[/tex].

Step-by-step explanation:

Since

[tex]64\dfrac45\text{miles}=\dfrac{64\times5+4}{5}\text{ miles}\\\\=\dfrac{324}{5}\text{ miles}[/tex]

[tex]18\dfrac45\text{ miles}=\dfrac{18\times5+4}{5}\text{ miles}\\\\=\dfrac{94}{5}\text{ miles}[/tex]

Total distance traveled during the trip = [tex]\dfrac{324}{5}+\dfrac{94}{5}+\dfrac{324}{5}+\dfrac{94}{5}[/tex]

[tex]= \dfrac{836}{5}\\\\=167\dfrac15\text{ miles}[/tex]

Hence, the distance traveled during their trip was [tex]167\dfrac15\text{ miles}[/tex].
