The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.
B. y = 50x + 300
Step-by-step explanation:
A.
The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.
For all the years after is when the line graph goes up which means they are adding to their total number.
B. For the city of Revere, they started out with 300 and are adding 50 Chromebooks every year.
Y represents the total and x is each counting year.
So the equation of the line is represented by y = mx + b
b is any constant which in this case is any initial amount (300)
and m is the rate/change which is the number represented by the value that will go up ever year of x (50)
So plug it all in equals:
y = 50x + 300

First Rate Rental Charges $40 a day plus $0.25 per mile. Star Rental charges $25 a
day plus $0.45 per mile. Write an equation that could be used to determine the number
of miles, m, that would result in the same cost for one day.
a. 40.25m=25.45m
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

[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]

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

What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, a wheel makes 35 revolutions per min.
Here,
35/1 minute × 1 minute/60 seconds
= 35/60
= 7/12 revolution per second
Therefore, the wheel makes revolutions per second is 7/12.

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
=======================================================
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.
