Solving systems using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x

-3x - 15 = y

Step 2: Solve for x

Substitute in y:                    2x = -3x - 15Isolate x terms:                   5x = -15Isolate x:                              x = -3

Step 3: Solve for y

Define equation:                     y = 2xSubstitute in x:                        y = 2(-3)Multiply:                                   y = -6

how do I find the inverse of the first function ?

Answers

Answer:

[tex]\boxed{\boxed{\pink{\sf \leadsto Hence \ the \ Inverse \ of \ the \ given \ function \ is \ x^2+2x-4 .}}}[/tex]

Step-by-step explanation:

A function is given to us , and we need to find its inverse. So the function is ,

[tex]\bf\implies f(x) = \sqrt{x + 5 } - 1 [/tex]

So , firstly replace x with y in the given function and then solve for y to get its inverse . Taking the given function ,

[tex]\bf \implies f(x) = \sqrt{x+5}-1\\\\\bf\implies y = \sqrt{x+5}-1 \\\\\bf\implies x = \sqrt{y+5}-1 \:\:\bigg\lgroup \red{\sf Replacing \ x \ with \ y .} \bigg\rgroup \\\\\bf\implies x + 1 = \sqrt{y+5}\\\\\bf\implies y+5 = (x+1)^2 \\\\\bf\implies y+5 = x^2+1 +2x \\\\\bf\implies y = x^2+1-5+2x \\\\\bf\implies y = x^2-4+2x \\\\\bf\implies \boxed{\red{\bf f^{-1}(x)= x^2+2x - 4 }}[/tex]

Here I have also attached the graph of , x² + 2x - 4 and √(x+5) - 1. Here blue graph is of √(x+5) - 1 & red of x²+2x-4.

Hence the inverse f (x) of the given function is + 2x - 4 .

The perimeter of a rectangle is forty inches. The length is
two inches more than three times the width. Find the dimensions of
the rectangle.

Answers

Let Width (inches)  = X

Let Length (inches) = 3x + 2

40 = (x) + (3x + 2) + (x) + (3x +2)

40 = 8x + 4

-4           -4

36 = 8x

/8     /8

4.5 = x (width)

Length = 3x + 2

length = 3(4.5) + 2

length = 13.5 + 2

length = 15.5 inches

CHECK

40 = 15.5 + 4.5 + 15.5 + 4.5

40 = 20 + 20

40 = 40

Mr. Demers is making a drink by adding flavor drops to his water. If he puts 3 drops in a 12 ounce glass of water, how many ounces does he use PER DROP?

Answers

Answer:

Step-by-step explanation: if he puts 3 drops in a 12 ounce glass of water he should be using 4 ounces per drop 12 ounces divided by 3 drops gives you 4 ounces per drop

Answer: 4 ounces per drop

=======================================================

Explanation:

"Per drop" means "per 1 drop" or "for each 1 drop".

We start off with the ratio of

3 drops: 12 ounces

Divide both parts of that ratio by 3 so that "3 drops" turns into "1 drop"

Doing so gets us the new ratio of

1 drop: 4 ounces

So he uses 4 ounces per drop.

b. 40m+0.25=25m+0.45
C. 40+0.25m=25+0.45m
d. 419+0.45m=25+0.25m

Answers

Answer:

b. 40m+0.25=25m+0.45

Step-by-step explanation:

Step one:

given data

First Rate Rental

Charges $40 a day plus $0.25 per mile.

let the number of days be m

and the total charges be y

y= 40+0.25m---------------------1

Star Rental

charges $25 a  day plus $0.45 per mile.

y= 25+0.45m-----------------------2

Step two:

equate 1 and 2 above we have

40+0.25m= 25+0.45m

What is equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, Mario received y text messages each minute for 10 minutes yesterday and received t text messages each minute for 20 minutes today.

Number of  text messages for yesterday = 10y

Number of  text messages for today = 20t

Total = 10y+20t

Hence, The total number of  text messages he received for two days is  10y+20t
