5 0

Answer:

(5x+3)/2

Step-by-step explanation:

f(x)=(2x-3)/5

f(x)=y

y=(2x-3)/5

interchanging role of x and y

x=(2y-3)/5

5x=2y-3

5x+3=2y

y=(5x+3)/2

the inverse if f(x) = (5x+3)/2

There are a total 40 cars

and there is x yellow cars

and there are nine times as much white cars (9x white cars) lol

simplify 10x=40

divide both sides by ten 10x/10=40/10

x=4

we are looking for the number of WHITE cars sooo we multiply by 9-

9x=36

how is this "hardddd" no offence*

Line / is shown on the graph below. If another line is drawn, perpendicular to line I, what must be its slope?
juin [17]

Answer:

Undefined

Step-by-step explanation:

The slope on the graph is horizontal so there's no slope and the answer is just y = 3

For a line to be perpendicular to a horizontal line, it is going to be a vertical line.

All vertical lines have an undefined slope.

If the hypotenus is 41 inches, and one of the legs is 40 inches what is the length of the other Leg
andre [41]
You find the answer through the Pythagorean theorem

a^2 + b^2 = c^2 a & b are the legs and c is the hypotenuse
a = 40
b = ?
c = 41

40^2 + b^2 = 41^2
1600 + b^2 = 1681
b^2 = 1681 - 1600
b^2 = 81
b = 9

the length of the other leg is 9

i hope you found this helpful!
