The answer is m = 20 because the rate of change is –3.

We can see that the difference between 26 and 23 is 3. Because the values are going down as x goes up, that means the change is negative. Therefore, the rate of change is -3.

According to the table, if x increases by 1 from 4 to 5, y decreases by 3.

Also, if x increases by 1 from 5 to 6, y must be 3 less than 23, or 20, for all 3 points to be collinear.

m = 20 because the rate of change is –3.

Brandi solved 16 / 5 by using a related multiplication expression. What multiplication expression did she is?

klemol [59]

The given question is wrong.

Question:

Brandi solved $\frac{1}{6}\div 5$ by using a related multiplication expression. What multiplication expression did she is?

Answer:

The related multiplication expression is $$\frac{1}{6}\times \frac{1}{5}$ .

Solution:

Given expression is $\frac{1}{6}\div 5$ .

We can write 5 as a fraction with denominator 1.

$$ \frac{1}{6}\div5=\frac{1}{6}\div \frac{5}{1}$

Using the fraction rule $$\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$ ,

$$\frac{1}{6}\div \frac{5}{1}=\frac{1}{6}\times \frac{1}{5}$

Now multiply the fractions using the rule $$\frac{a}{b}\times \frac{d}{c}=\frac{a\times d}{b\times c}$ ,

$$\frac{1}{6}\times \frac{1}{5}=\frac{1\times1}{6\times5}$

Let us multiply the numbers in the numerator and denominator separately, we get

$$\frac{1\times1}{6\times5}=\frac{1}{30}$

Hence the related multiplication expression is $$\frac{1}{6}\times \frac{1}{5}$ .

|x - 12| = 4<br> please provide an explanation

geniusboy [140]

Answer: x = 16, x = 8

Step-by-step explanation:

|a| > 0, there are two solutions

|a| = 0, there is one solution

|a| < 0, there are no solutions

So, in this problem, we have two solutions.

In absolute value, the expression inside can be equal to itself OR its opposite.

Ex: |y| = y, |y| = -y

So, we can write two equations:

x - 12 = 4, x = 16

-x+12 = 4, x = 8

Check: |16 - 12| = |4| = 4

Check: |8 - 12| = |-4| = 4
