Let me = slope

m = (18 - (-2))/(4 - 0)

m = 20/4

m = 5

We now plug slope 5 and one of the given points into the point-slope formula.

y - y_1 = m(x - x_1)

y - 18 = 5(x - 4)

y - 18 = 5x - 20

y = 5x - 20 + 18

y = 5x - 2

WHAT IS THE LENGTH!!!
Murljashka [212]

The figure is a trapezoid (or trapezium), and the exact length of the trapezoid is 5 units

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

The figure is a trapezoid with the following parameters:

Area = 107.95

Base= 12

Height = 12.7

Length = x

The area of a trapezoid is:

Area = 0.5 * (Base + Length) * Height

So, we have:

0.5 * (12 + Length) * 12.7 = 107.95

Evaluate the product

(12 + Length) * 6.35 = 107.95

Divide both sides by 6.35

12 + Length = 17

Subtract 12 from both sides

Length =  5

Hence, the length of the trapezoid is 5 units

Simplify the following Expression by combining like terms:<br> y+ 3x + 4y + 2x + 3y + 3x
lys-0071 [83]

Answer:

8x+8y

Step-by-step explanation:

y + 3x + 4y + 2x + 3y +3x

<em>With</em><em> </em><em>this</em><em> </em><em>we</em><em> </em><em>group</em><em> </em><em>x</em><em> </em><em>with</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>y</em><em> </em><em>and </em><em>in</em><em> </em><em>ascending</em><em> </em><em>order</em><em> </em><em>so</em><em> </em><em>x</em><em> </em><em>comes</em><em> </em><em>before</em><em> </em><em>y</em>

3x+2x+3x

And the y with y

y+4y+3y

Which is;

3x+2x+3x+y+4y+3y

8x+8y

PLEASE HELP!! Question is below
maria [59]

Answer:

C

Step-by-step explanation:

Complementary means that the angles have a sum of 90° so we can write:

m∠A + m∠B = 90° → 3x + 2 + 8x = 90

11x + 2 = 90

11x = 88

x = 8 which means that m∠B = 8x = 8 * 8 = 64°.

Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.

Please help, my computer is about to die and this is due in a few minutes. Will mark brainlist if correct.
lidiya [134]

Answer:

x = 1.5

Step-by-step explanation:

Here, we want to solve for the value of x

By using the tangent from the same point theorem, we have it that;

lh^2 = lj * lk

1^2 = (0.5) * (0.5 + x)

1 = 0.5x + 0.25

1-0.25 = 0.5x

0.5x = 0.75

x = 0.75/0.5

x = 1.5
