Determine whether the two functions are inverses.

f(x) = 5x+4 and g(x)=x-4/5

The two functions are inverses.
The two functions are not inverses.

Answers

Answer:

The two functions are inverses.

Step-by-step explanation:

We are supposed to find whether the two functions are inverses.

\(f(x)=5x+4\)

\(g(x)=\frac{x-4}{5}\)

To find the inverse of f(x)

y = 5x+4

y-4=5x

\(\frac{y-4}{5}=x\)

Replace x with y and y with x

So, \(\frac{x-4}{5}=y\)

So, \(\frac{x-4}{5}=g(x)\)

So,The two functions are inverses.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

what point below is the solution to the expression 2x+y=12
A) (4,2) C) (8,-1)
B) (3,6) D) (0,6)

Answers

The answer is B. If you substitute 3 for x and 6 for y, you get 2(3)+(6)=12, and that simplifies to 6+6=12, which then adds up to 12=12. Hope this helps!

Answer:

Step-by-step explanation:

It's B.

Let's rewrite the expression like this :

2x+y=12 ⇒ y=12-2x

and try given values for x :

if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrong

Answers

Answer:

Step-by-step explanation:

Working days : 5

Working hours : 3.5 + 4 = 7.5 Hours

Earning in a day = 7.5 * 18.75 = 140.625

Earning in the week (working days only): 140.625 * 5 = 703.125

In the last week Mrs. Rodriguez earned $703.125

How to know how much money did she make for the entire week's work ?

According to the problem,

Mrs. Rodriguez worked 5 days last week. She worked 3.5 hours before and 4 hours after lunch. Mrs. Rodriguez earned $18.75 per hour.

Total hours of work = (3.5 + 4) hours = 7.5 hours in one day

In 5 days she worked (7.5 x 5) hours = 37.5 hours

In the last week Mrs. Rodriguez worked 37.5 hours.

∴ Amount of money she earned =  $ (37.5 x 18.75) = $703.125

Answer:

The solution to the equation is:

\(x=-5\)

Step-by-step explanation:

Step 1: Rearrange the equation

Since we have to solve the equation for \(x\), let's bring the \(\frac{x}{6}\) to the other side with all the other variables:

\(\frac{5x}{3}-x=\frac{x}{6}-\frac{5}{2}\\\\\text{Subtract}~\frac{x}{6}~\text{from both sides of the equation:}\\\frac{5x}{3}-x-\frac{x}{6}=\frac{x}{6}-\frac{x}{6}-\frac{5}{2}\\\\\text{Simplify:}\\\frac{5x}{3}-x-\frac{x}{6}=-\frac{5}{2}\)

Step 2: Make use of the distributive property

The property states that when there's an expression like \(3(2x+6)\), it can be written as \(3(2x)+3(6)\), or vice versa.

In the equation we have found above, the left hand side of the equation has a common variable: \(x\)

Using the principle of distributive property, we can arrange the left hand side differently:

\(\frac{5x}{3}-x-\frac{x}{6}=-\frac{5}{2}\\x(\frac{5}{3}-1-\frac{1}{6})=-\frac{5}{2}\)

We have arranged the left hand side as such, that distributive property is applicable for it.

Step 3: Solving

First, let's simplify the equation:

\(x(\frac{5}{3}-1-\frac{1}{6})=-\frac{5}{2}\\\\\text{Add the numbers inside the bracket:}\\x(\frac{1}{2})=-\frac{5}{2}\)

Now, let's solve it:

\(\frac{1}{2}x=-\frac{5}{2}\\\\\text{Multiply both sides of the equation by}~2:\\\frac{1}{2}x\times 2=-\frac{5}{2}\times 2\\\\\text{Calculate:}\\\frac{2}{2}x=-\frac{10}{2}\\x=-5\)

So first we want to get rid of the fraction to do this we can times by the reciprocal, in this case -8/3x
-8/3x(3x/-8) cancels out to equal 1
1= -21/4
-8/3x(-21/4) is equal to 14/x
times both sides by 14
14= x
To double check we can plug this into the equation

3(14)
42/-8 we can simplify this by diving by 2
21/-8= -21/8 these are the same

Answer

x=14

Explanation

3x/-8=-21/4
