USPshnik [31]

Answer:

c = -75/14 OR c = -5.357143

Step-by-step explanation:

Simplify both equations:

1.2x + 7 - 5x =

-3.8x + 7

2.2c - 3 = 2(6 - c) + 7c =

c = −5.357143

OR

c = -75/14

The question wasn't quite clear, if this wasn't correct, please elaborate on what needed to be solved, and I'll fix my answer.

Hope this helped!

serg [7]

Answer:

y = 4x + 8

Step-by-step explanation:

The linear equation can be written in the form y = mx + b. "y" and "x" stay as they are. The "m" is the slope or rate of change. The b is the y-intercept.

Hope it helps!!!

What is the surface area of the triangular prism?​
AlladinOne [14]

Answer:

<h3>The surface area of the prism is A prism=204m2</h3>

Step-by-step explanation:

Area is the space that is contained in a two-dimensional figure.

Surface area is the total area of all of the sides and faces of a three-dimensional figure.  

To find the surface area, the area of each face is calculated and then add these areas together.

To find the area of a rectangle, multiply the length by the width .

From the graph the length of the rectangle is 10 m and the width is 8 m. Therefore, the area of the bottom face is

From the graph the length of the rectangle is 10 m and the width is 5 m. Therefore, the area of one of the rectangular side faces is

To find the area of a triangle use the following formula  where b is the base and h is the height.

From the graph the base of the triangle is 8 m and the height is 3 m. Therefore, the area of one of the triangular faces is

The surface area of the prism is the sum of the area of the bottom face, the area of the two rectangular side faces, and the area of the two triangular faces

A boat is heading towards a lighthouse, whose beacon-light is 126 feet above the water. From point AA, the boat’s crew measures
vredina [299]

Using the slope concept, it is found that the distance from point A to point B is of 887 feet.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>.

It's also the tangent of the angle of depression.

In this problem, the vertical change is of 126 feet.

At point A, the angle is of 6º, while the horizontal position is of x_A, hence:

\tan{6^\circ} = \frac{126}{x_A}

x_A = \frac{126}{\tan{6^\circ}}

x_A = 1198.8

At point B, the angle is of 22º, while the horizontal position is of x_B, hence:

\tan{22^\circ} = \frac{126}{x_B}

x_B = \frac{126}{\tan{22^\circ}}

x_B = 311.9

Hence, the distance in feet is of:

d = x_A - x_B = 1198.8 - 311.9 \approx 887
