HERE ARE TWO NUMBER MACHINES A AND B

nika2105 [10]

Answer:

$x=-7$

Step-by-step explanation:

We can write them both like functions like this

$A=5x-4$

$B=3x+8$

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

$A=3B$

we replace with the functions

$5x-4=3(3x+8)$

we solve for x

$5x-4=9x+24\\5x-9x=24+4\\-4x=28\\x=\frac{28}{-4}\\x=-7$

The output that makes the out put of A 3 times teh output of B is $-7$

Arrange the given steps in the correct order to find A and B if A and B are two sets where A – B = {1, 5, 7, 8}, B – A = {2, 10}

GarryVolchara [31]

Answer:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}

Step-by-step explanation:

Here as given in the question:

A – B = {1, 5, 7, 8} ⇒ {1, 5, 7, 8} is in A not in B.

B – A = {2, 10} ⇒ {2, 10} is in B not in A

A ∩ B = {3, 6, 9} ⇒ {3, 6, 9} is BOTH in A and B.

Step 1:

Set A can also be expressed as : A = (A - B) ∪ (A ∩ B)

Set A can also be expressed as : B = (B - A) ∪ (A ∩ B)

Step 2:

Substituting the values of (A - B) and (B - A)

A = {1, 5, 7, 8} ∪ {3, 6, 9}

B = {2, 10} ∪ {3, 6, 9}.

Step 3:

Finding the UNION of the above two sets, we get:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}

How do you convert 5y-x+4=0 into y=mx+b form?

Mashutka [201]

$5y-x+4=0$

~Add x to both sides

$5y+4=x$

~Subtract 4 from both sides

$5y=x-4$

~Divide both sides by 5

$\frac{5}{5}y= \frac{1x}{5} - \frac{4}{5}$

~Simplify

$y= \frac{1}{5} x- \frac{4}{5}$

~M= $\frac{1}{5}$

~B= $-\frac{4}{5}$
