Not a function because input has two outputs. 9 goes to two different numbers which make it not a function

How many Solutions does this equation have<br> -2(5x + 6) = 2( -5x - 1)

None. Because when you solve for x, x is eliminated.

An open box is made from a 20 cm x 3 cm piece of tin by cutting a square from each corner and folding up the edges. The area of

Marta_Voda [28]

Answer:

Length of the final sides: 6 cm and 16 cm

Step-by-step explanation:

The lengths of the sides of the original box are

$L=20 cm\\W=10 cm$

Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:

$L'=L-2x\\W'=W-2x$

We also know that the area is

$A=96 cm^2$

And the area can be written as product of length and width, therefore:

$A=L'W'$

So we find:

$A=(L-2x)(W-2x)\\96=(20-2x)(10-2x)$

Solving for x,

$96=200-20x-40x+4x^2\\4x^2-60x+104=0\\\\x^2-15x-26=0$

Which has two solutions:

x = 13 cm (this is larger than the initial length of the width, therefore we discard it)

x = 2 cm

So, the length of the new sides are

$L=20-2x=20-2(2)=16 cm\\W=10-2x=10-2(2)=6 cm$

Enter the value of b that makes the statement true: 5xb is less than 5 but greater than 0.

AlexFokin [52]

0<5xb<5 divide all terms by 5

0<xb<1 divide all terms by x

0<b<x

If you meant 5b as in 5*b then:

0<5b<5 divide all terms by 5

0<b<1

b is infinitely many values between 0 and 1.

Am eastern cotttentail rabbit and ferret weigh 7 lbs together. The ferret weighs 2 lbs more than the rabbit. Create a system of

aleksklad [387]

Answer:

Step-by-step explanation:

The first equation is the weights of the rabbit and the ferret together which is

r + f = 7.

The second equation puts the weight of the ferret in terms of the rabbit. If the ferret's weight is 2 pounds more than the rabbit, then

f = r + 2 (the word "is" means equals). Since we know what f is equal to, we will sub it into the first equation and solve for r:

r + (r + 2) = 7 and

2r + 2 = 7 and

2r = 5 so

r = 2.5 pounds.

A rabbit weights 2.5 pounds and the ferret weights 7 - 2.5 which is 4.5 pounds.
