Answer:

Each strip is 117.6 cm

Step-by-step explanation:

I created a proportion of hearts to others.  On strip A there is 1 heart to 2 others and B there is 1 heart to 3 others.  I added them and got a proportion of 2 hearts to 5 others for both. With a total of 56 hearts, I set up a proportion to determine the total stickers

2/5=56/x

When I cross multiply, I get 2x=280 and x=140

so for the 56 total hearts, I have 140 others.  I added those to get the total stickers and got 196.  I multiplied that by 1.2cm and got 235.2 cm for both. Since both are the same size, just divide that by 2 and get 117.6 cm each.

Directions: Given the point and slope, write the equation of the line.<br> (4, 2); slope = 36
olga nikolaevna [1]

Answer:

y - 2 = 36(x - 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 36 and (a, b ) = (4, 2 ) , then

y - 2 = 36(x - 4) ← equation of line

What is the inverse of the function f(x) = 2x + 1?
charle [14.2K]

Answer:

f^{-1} (x) = \frac{x-1}{2}

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

\frac{y-1}{2} = x

Change y back into terms of x with x = f^{-1} (x) , so

f^{-1} (x) = \frac{x-1}{2}
