To do this we set 80% = 32 and find 10%
10% = 32/8 = 4
Therefore we can say that 100% = 4 * 10 = 40

40 ticket were given to the teachers.

What is the rate of change for the linear function f(x)=-2x-5 over any interval?

Dmitry [639]

To solve this problem you must apply the proccedure shown below:

1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.

2. You have the equation of the line has the following form:

$y=mx+b$

Where $m$ is the slope and $b$ is the y-intercept.

3. Then, you have that the slope of the function $f(x)=-2x-5$ is:

$m=-2$

Therefore, the answer is: $-2$

Math help please question in the picture

Kazeer [188]

This took me a while but I'm pretty sure the answer is
$y = - \frac{1}{3} x - 1$
I had to review perpendicular bisectors but yeah it has to do with the midpoint and point slope formula

−6x + 14 < −28 OR 9x + 15 ≤ −12. solve for x.

sasho [114]

Answer:

x>7 or x ≤ -3

Step-by-step explanation:

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).
