Answer:

No it is D.52

Step-by-step explanation:

The angle has to equal 180 degrees.

180-76=104

Answer:

$\boxed {\tt D. \ x=52}$

Step-by-step explanation:

The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.

$2x+76=180$

Solve for x by isolating x on one side of the equation.

76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.

$2x+76-76=180-76\\2x=180-76\\2x=104$

x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

$2x/2=104/2\\x=104/2\\x=52$

x is equal to 52 and D is the correct answer.

Find the slope of the line that passes through the following points. Write "undefined" if the slope is undefined.

Katyanochek1 [597]

The slope of the line that passes through the following points is undefined

Solution:

Given that, We have to find the slope of line passing through two points

Given points are (-1, 5) and (-1, 6)

The slope of line is given by formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

From given,

$(x_1, y_1) = (-1, 5)\\\\(x_2, y_2) = (-1, 6)$

Substituting the values we get,

$m = \frac{6-5}{-1-(-1)}\\\\m = \frac{1}{-1+1}\\\\m = \frac{1}{0}$

Thus the slope is undefined
