Answer:

There are multiple answers depending on what you're looking for (down below)

Step-by-step explanation:

To SIMPLIFY or STANDARD FORM or EVALUATE: -x+25

to FACTOR the polynomial: -(x-25)

Solve for x: invalid

Find DOMAIN & RANGE : - ♾ , ♾

find X & Y INTERCEPT: x intercept: 25,0 y intercept: 0,25

finding INVERSE: f-1(c) = -x + 25

lmk if anything is wrong :)

Ok need help this is the question :Use the Pythagorean theorem to write an equation for the distance Jane's trainer bikes.

IRINA_888 [86]

Answer:

<em>Jane traveled 8 miles farther then her trainer</em>

Step-by-step explanation:

<u>The Pythagora's Theorem</u>

In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:

$c^2=a^2+b^2$

Where

c = Hypotenuse or largest side

a,b = Legs or shorter sides

Jane's path from the Health Club to the end of her route describes two sides of a right triangle of lengths a=16 miles and b=12 miles.

Her total distance traveled is 16 + 12 = 28 miles

Her trainer goes directly from the Health Club to meet her through the hypotenuse of the triangle formed in the path.

We can calculate the length of his route as:

$c=\sqrt{16^2+12^2}$

$c=\sqrt{256+144}=\sqrt{400}=20$

c = 20 miles

The difference between their traveled lengths is 28 - 20 = 8 miles

Jane traveled 8 miles farther then her trainer

Why do some merchants, particularly smaller businesses, set a minimum purchase of $10 for any credit card transaction, or simply

amm1812

Because accepting credit cards cost the business small transaction fees. These businesses already have a paper thin profit margin, meaning if you buy less than $10 and use credit card, their profit is little to non-existent.

What does 4 5/8 - 1 2/5 equal?

mihalych1998 [28]

$4 \frac{5}{8} - 1 \frac{2}{5} \\ \\ \frac{37}{8} - \frac{7}{5} \\ \\ \frac{185}{40} - \frac{56}{40} = \frac{185 - 56}{40} \\ \\ = \frac{129}{40} = 3.225 = 3 \frac{9}{40}$

I hope I helped you^_^
