Answer:

52^0{

Step-by-step explanation:

m∠4 and m∠8 are corresponding angles.

So, m∠4 = 128° = m∠8

Now, m∠7+m∠8=180° (linear pair)

Which is the rate of change for the interval between 2 and 6 on the x-axis?
nadezda [96]

Answer:

3

Step-by-step explanation:

I think you misses attaching the photo, so please have a look at my photo for your better understanding.

We know the formula for rate of change of the  parabola line:

\frac{f(b)- f(a)}{b-a}

Given here:

a= 2 => f(a) = 2

b=6 => f(b) = 2

Substitute all the values into the function, we have:

\frac{14-2}{6-2} = 3

So the rate of change is 3

The points ????(0,0), ????(−4,1), ????(−3,5), and ????(1,4) are the vertices of parallelogram OABC Is this parallelogram a
gavmur [86]

Answer:

Yes, parallelogram OABC is a rectangle.

Step-by-step explanation:

The vertices of a parallelogram are O(0,0), A(-4,1), B(-3,5) and C(1,4).

A parallelogram is a rectangle if its any two adjacent sides are perpendicular to each other.

product of slopes of two perpendicular lines is -1.

Formula for slope is

Slope=\dfrac{y_2-y_1}{x_2-x_1}

Using the formula we get

m_{OA}=\dfrac{1-0}{-4-0}=-\dfrac{1}{4}

m_{AB}=\dfrac{5-1}{-3-(-4)}=-\dfrac{4}{1}=4

m_{OA}\times m_{AB}=-\dfrac{1}{4}\times 4=-1

It means OA is perpendicular to AB.

Since two adjacent sides are perpendicular, therefore the given parallelogram OABC is a rectangle.
