The answer is 24 F because if you add 15 plus 9 equals 24 so 24 F degrees

22. What is the average rate of change over the interval (-3, 2)? SEE EXAMPLES

ivann1987 [24]

The average rate of change over the interval (-3, 2) is 1

<h3>Average rate of change</h3>

The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation

<h3>Interval</h3>

The interval is given as: (-3,2)

From the graph, we have:

f(-3) = -5
f(2) = 0

So, the average rate over these intervals is calculated as:

$m = \frac{f(b) - f(a)}{b -a}$

This gives

$m = \frac{f(-3) - f(2)}{-3 -2}$

Substitute known values

$m = \frac{-5- 0}{-3 -2}$

Simplify

$m = \frac{-5}{-5}\\\\$

$m =1$

Hence, the average rate of change is 1

What is the value of the variable in the equation, r-17=22 *

aleksklad [387]

Answer:

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7, or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

Answer: x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

What other circle theorems can cyclic quadrilaterals can be related to? Explain how.

Nitella [24]

The circle theoremss that cyclic quadrilaterals can be related to include:

Every corner of the quadrilateral touches the circumference of the circle.
The ratio between the diagonals and the sides can be defined.
The product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.

<h3>What is a cyclic quadrilateral?</h3>

It should be noted that cyclic quadrilateral simply means a quadrilateral that's drawn inside a circle.

In this case, every corner of the quadrilateral must touch the circumference of the circle.

Also, the product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.

Please answer this question now in two minutes

kykrilka [37]

Answer:

$y=\frac{3}{2}x+4$

Step-by-step explanation:

So the line C equation is $y=\frac{3}{2}x+2$ and line D is parallel to it and it passes through the point (4,10) and we need to ding the equation for line D.

So first we have a graph with line C listed and (4,10).

And we can keep listing more equations till we find the right one which is $y=\frac{3}{2}x+4$ .

So I got this by knowing that in parrelel lines the slope is the same but the y intercept changes which is why it was fast to find the answer.
