Answer:

- 13 $\frac{3}{4}$

Step-by-step explanation:

- 4 $\frac{1}{4}$ - 9 $\frac{1}{2}$ ( change mixed numbers to improper fractions )

= - $\frac{17}{4}$ - $\frac{19}{2}$ ( multiply numerator/denominator by 2 )

= - $\frac{17}{4}$ - $\frac{19(2)}{2(2)}$

= - $\frac{17}{4}$ - $\frac{38}{4}$ ( add the numerators leaving the common denominator )

= $\frac{-17-38}{4}$

= $\frac{-55}{4}$

= - $\frac{55}{4}$

= - 13 $\frac{3}{4}$

Two types of sandwiches were made for a tea party. 55% of the sandwiches were cheese sandwiches and the rest were chicken sandwi

Helen [10]

"To solve this problem, the formula can be used

I = P / T

Where I is the fraction of the sample

P is the amount of the sample

T is the total amount of sample

Since P = 252 chicken sandwiches and I = 0.55

And solve for T

T = 252 / 0.52

T = 458 sandwiches in total"

hope this helps

Express it in slope-intercept form.

FinnZ [79.3K]

Answer:y=3/2x-3

Step-by-step explanation: the slope of the graph is (y2-y1)/(x2-x1)

If we take points (0,-3) (2,0) the slope would be (0--3)/(2-0) = 3/2

And the y-intercept of the slope is -3

Find the inverse function of m(x) = 5x - 5 A m-1(x) = 5x + 5 B m-1(x) = -5x + 5 C m-1(x) = x+5/5 D m-1(x) = x+5/-5x

bogdanovich [222]

Hi there!

$m(x) = 5x - 5$
First replace m(x) by y.

$y = 5x - 5$
To find the inverse function we must switch the places from the variables x and y.

$x = 5y - 5$
Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.

$x + 5 = 5y$
Switch sides.

$5y = x + 5$
And finally divide both sides by 5.

$y = \frac{x + 5}{5}$
And therefore we can conclude the following:

$m {}^{ - 1} (x) = \frac{x + 5}{5}$
The answer is C.
~ Hope this helps you!
