Answer:

$\dfrac{1-10}{8-5}$

Step-by-step explanation:

The average rate of change between two points on a graph is ...

average rate of change = slope = rise/run

The rise over the given interval is the function value at x=8 less the function value at x=5. That is, ...

rise = 1 - 10

The run is the difference in the x-values:

run = 8 - 5

Then the average rate of change is ...

average rate of change = rise/run = (1 -10)/(8 -5)

_____

Here, the points are written as (x, y), so the only pair we're interested in is ...

(5, 10) and (8, 1)

Match each equation to its factorized version and solution.

bagirrra123 [75]

Answer:

$24x -{6x}^{2} = 0 \: matches \: with \: 6x(4 - x) \: and \: the \: solution \: x = 0 \ \: or \: \: x = 4$

$2 {x}^{2} + 6x = 0 \: matches \: with \: 2x(x + 3) = 0 \: and \: the \: solution \: x = 0 \: or \: x = - 3$

$4x - {x}^{2} = 0 \: matches \: with \: x(4 - x) = 0 \: and \: the \: solution \: x = 0 \: or \: x = 4$

$14x - {7x}^{2} = 0 \: matches \: with \: 7x(2 - x) = 0 \: and \: the \: solution \: x = 0 \: or \: x = 2$

PLEASE HELP ME WITH THESE FOUR QUESTIONS TYSMMM!!! THANK YOU

Dima020 [189]

Answer:

$107^\circ, 133^\circ, 20^\circ, \text{and}, 23^\circ$

Step-by-step explanation:

9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:

$x+73^\circ=180^\circ$

$x=107^\circ$

10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:

$147^\circ=x+14^\circ$

$x=147^\circ-14^\circ$

$x=133^\circ$

11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:

$180^\circ-3x=2x+20^\circ$

Solving for 'x' we get:

$180^\circ-20^\circ=3x+2x$

$5x=160^\circ$

$x=32^\circ$

12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:

$(7x-11)^\circ=(4x+58)^\circ$

$7x-4x=58^\circ+11^\circ$

$3x=69^\circ$

$x=\frac{69}{3}=23^\circ$

Use complete sentences to describe the relationship between sets A and B if A ⊆ B.

Alex17521 [72]

Answer:

Step-by-step explanation:

A is a subset of B while B is the universal set.

AB = A U B

A is a subset of B. That is A is contained in B.
