Simplify algebraic expression 3/4 (1/2X - 12) + 4/5

Nata [24]

$\frac{3}{4} ( \frac{1}{2} x-12)+ \frac{4}{5} =$

$=\frac{3}{4} ( \frac{x}{2} -12)+ \frac{4}{5}$

$= \frac{3x}{8} -9+ \frac{4}{5}$

$= -\frac{41}{5} + \frac{3x}{8}$

The answer is: $-\frac{41}{5} + \frac{3x}{8}$

Answer:

Step 3, because the solution should also include all the values for x between the two given values

Step-by-step explanation:

step 1

we have

$y_1=\left|x-4\right|$

$y2=1$

step 2

The graph in the given problem

step 3

Identify the solution when $y1\leq y2$

$\left|x-4\right|\le1$

using a graphing tool

The solution is the interval -----> [3,5]

see the attached figure

All real numbers greater than or equal to 3 and less than or equal to 5

therefore

The first step in which the student made an error is step 3

In the following equation, when x=3, what is the value of y? -4x + 3y = 12

deff fn [24]

Answer:

y = 8

Step-by-step explanation:

-4(3) = -12

to get -12 to 12 you need to add 24 to -12 to make it 12.

so 3 (8) = 24

so -12 + 24 =12
