Answer:

x = -63

Step-by-step explanation:

To isolate x, you must first do the reciprocal on both sides, so you do 7/x times x/7 cancel that out, then do it on the other side, so -9/1 x 7/x = -63.

The length of the hypotenuse of a right triangle is 50 inches. Determine the length of the legs if each leg is the same length.

algol13

Answer:

25√2 ≈ 35.36 inches

Step-by-step explanation:

The Pythagorean theorem can be used to find the leg length for the given conditions. It tells you the relation between legs a, b, and hypotenuse c is ...

c² = a² +b²

If a=b, and c=50, this becomes ...

50² = a² +a²

1250 = a² . . . . divide by 2

25√2 = a . . . . take the square root

The length of each leg is 25√2 ≈ 35.36 inches.

There are three options for fans purchasing a band's new release CD. They can purchase the CD, a premium CD bundle, or a deluxe

cluponka [151]

Answer:

The price of CD's = $15

The price of deluxe bundles = $85

The price of premium bundles. = $ 35 ....

Step-by-step explanation:

Let c represents the number of CD's

Let d represents the number of deluxe bundles

Let p represents the number of premium bundles.

Now according to the given statement:

c = $15

d = c+2p =

d = 15+2p --------equation 1

455c+87p+35d = $12,845 --------equation 2

Now substitute the value of d in equation 2 to find the value of p

455c+87p+35d = $12,845

455(15)+87p+35(15+2p) = $12,845

6825+87p+525+70p=$12,845

Now combine the like terms:

6825+157p+525 = $12,845

Now shift all the like terms to the R.H.S

157p= 12845-6825-525

157p = 5495

Divide both sides by 157

157p/157 = 5495/157

p = 35

Now substitute the value p =35 in equation 1.

d = 15+ 2p

d = 15+2(35)

d = 15+70

d = 85

Therefore we have found that,

The price of CD's = $15

The price of deluxe bundles = $85

The price of premium bundles. = $ 35 ....

The graph of y=1/x is shown below. Draw the graph of its inverse.

lord [1]

Y=1/x solve for x

x=1/y now reverse lables...

y=1/x

Yes that is the same equation you started with. What that means is the the inverse function in this case produces the same exact graph :)
