Answer:

m∠CBD = 68°

Step-by-step explanation:

Step 1: Find x.

4x + 52 + 8x - 10 = 90\\12x + 42 = 90\\12x = 48\\x = 4

Step 2: Plug it in the angle in question.

What is the poinet-slope form of the equation for the line in the graph?​
Ne4ueva [31]

Answer:

y -5 = \frac{9}{13}(x - 7)

Step-by-step explanation:

Given :

Two points are given in graph (-6, -4) and {7, 5).

The point-slope form of the equation of a straight line is:

y -y_{1} = m(x - x_{1})------------(1)

Let (x_{1}, y_{1})=(7,5) and (x_{2}, y_{2})=(-6,-4)

The slope of the line m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}

Put all known value in above equation.

m=\frac{-4- 5}{-6- 7}

m=\frac{-9}{-13}

m=\frac{9}{13}

The slope of the line m=\frac{9}{13}

We know m, and also know that (x_{1}, y_{1})=(7,5), so we put these value in equation 1.

y -5 = \frac{9}{13}(x - 7)

Therefore, the equation of the line is y -5 = \frac{9}{13}(x - 7).

A negative scale factor inverts the original image and scales it to what the number is.

An expansion means the image would get bigger.

For an image to get bigger the scale factor needs be be greater than 1.


-2 means the image would increase in size and be inverted.

2 means the image would increase in size.


The two correct scale factors are -2 and 2.
