Good morning ☕️

Answer:

Step-by-step explanation:

the surface area of the triangular prism =

2×(the base’s area) + the lateral area

the base’s area =

$\frac{6*4}{2} =\frac{24}{2} =12$

the lateral area =

9×(6 + 5 + 5) = 9×16 = 9×16 = 144

finally,

the surface area of the triangular prism = 24 + 144 = 168

X - (9x - 10) + 11 = 12x + 3(-2x + $\frac{1}{3}$ ) equals x = $\frac{10}{7}$ .

First, simplify brackets. / Your problem should look like: x - 9x + 10 + 11 = 12x + 3(-2x + $\frac{1}{3}$ ).
Second, simplify x - 9x + 10 + 11 to -8x + 10 + 11. / Your problem should look like: -8x + 10 + 11 = 12x + 3(-2x + $\frac{1}{3}$ ).
Third, simplify -8x + 10 + 11 to -8x + 21. / Your problem should look like: -8x + 21 = 12x + 3(-2x + $\frac{1}{3}$ ).
Fourth, expand. / Your problem should look like: -8x + 21 = 12x - 6x + 1.
Fifth, simplify 12x - 6x + 1 to 6x + 1./ Your problem should look like: -8x + 21 = 6x + 1.
Sixth, add 8x to both sides. / Your problem should look like: 21 = 6x + 1 + 8x.
Seventh, simplify 6x + 1 + 8x to 14x + 1. / Your problem should look like: 21 = 14x + 1.
Eighth, subtract 1 from both sides. / Your problem should look like: 21 - 1 = 14x.
Ninth, simplify 21 - 1 to 20. / Your problem should look like: 20 = 14x.
Tenth, divide both sides by 14. / Your problem should look like: $\frac{20}{14}$ = x.
Eleventh, simplify $\frac{20}{14}$ to $\frac{ 10}{7}$ . / Your problem should look like: $\frac{10}{7}$ = x.
Twelfth, switch sides. / Your problem should look like: x = $\frac{10}{7}$ which is your answer.

Help this is my last question can somebody plz b help me?

Kazeer [188]

Answer:

y = (4/3)x

Step-by-step explanation:

You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:

12 = (4/3)(9) + b

12 = 12 + b

b = 0

So, y = (4/3)x

Hope that helps! :D

Anon25 [30]

The slope of the parallel line is 0 and the slope of the perpendicular line is undefined

<h3>How to determine the slope?</h3>

The equation is given as:

y = 1

A linear equation is represented as:

y = mx + c

Where:

m represents the slope

By comparison, we have:

m = 0

The slope of the parallel line is:

Slope = m

This gives

Slope = 0

The slope of the perpendicular line is:

Slope =-1/m

This gives

Slope = -1/0

Slope = undefined

Hence, the slope of the parallel line is 0 and the slope of the perpendicular line is undefined
