Step-by-step explanation:

a squared + b squared = c squared

15 squared + b squared = 17 squared

then find the value of b squared

225 + b squared = 289

subtract 225 on both sides

b squared = 64

b = 8

I'm not very sure but I hope you get the idea

Answer: $15.51

Step-by-step explanation: 28.2 times 0.55 is $15.51

Answer:

If you're asking for the total amount of money required, then the answer is $15.51 for the chicken wire.

Step-by-step explanation:

You have the unit price of $0.55 per foot, and need to cover 28.2 feet. So by simply multiplying $0.55 by 28.2, you get the total cost of $15.51 for the 28.2 feet of chicken wire.

Answer:

9y+54

Step-by-step explanation:

Multiply the number on the outside of the parenthesis with both of the numbers on the inside of the parenthesis.

9*y=9y

9*6=54

Hope this helps!

Answer:

9y+54

Step-by-step explanation:

Alright we are going to be using the distributive law/Properties

The distributive property states that a(b+c)=ab+ac

So a=9,b=y,c=6

9y+9*6  

So you multiply the numbers

9y+54

So therefore, your answer would be 9y+54

very very very sorry if it's wrong I apologize

Answer:

Slope = -3/1

Step-by-step explanation:

As the hint says, slope is the change in y over the change in x or

m = (y2 - y1)/(x2 - x1)

m = (9 - 15)/(2 - 0)

m = -6/2

m = -3/1

Answer:

50r-93s

Step-by-step explanation:

-9(-4r + 6s) + 3s – 7(6s – 2r)

distribute

36r-54s+3s-42s+14r

add like terms

50r=93s

Answer:

The correct answer is A. y = 5 + 1.5x

Given:

Carmen rents roller skates for $5 plus $2 for every hour she uses them.

To find:

The expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.

Solution:

We have,

Fixed rent = $5

Additional rent = $2 per hour.

Let x be the number of hours.

So, additional rent is $2x.

Now,

Total rent = Fixed rend + Additional rent

                = $(5+2x)

So, the expression for total cost is $(5+2x).

Carmen rent them for 4 hours. So, x=4 and the total cost is

[tex]\text{Total cost}=5+2(4)[/tex]

[tex]\text{Total cost}=5+8[/tex]

[tex]\text{Total cost}=13[/tex]

Therefore, the total cost of 4 hours is $13.

Answer:

a=146

Step-by-step explanation:

using the fact that a straight angle is always 180:

180-34=a

a=146

Answer:

146°

Could you please give me brainliest, I really need it.

Step-by-step explanation:

Supplementary angle: Two angles that add up to 180°

Given angle: 34°

180°-34°= 146°

Answer:

20v2−40v+20

Step-by-step explanation:

=(4v+−4)(5v+−5)

=(4v)(5v)+(4v)(−5)+(−4)(5v)+(−4)(−5)

=20v^2−20v−20v+20

= 20v^2-40v+20

You can easily do this by using the FOIL method.

F - first -  in this case, 4v and 5v

O - Outside - in this case, 4v and -5

I - Inside - in this case, -4 and 5v

L - Last - In this case, -4 and -5

Then you find the like terms and add them together and then you have your answer which is also in standard form.

Answer:

a) 4(x - 2) = 100

4x - 8 = 100

4x = 92

x = 23

b) 2(x - 2) = 50

2x - 4 = 50

2x = 46

x = 23

Step-by-step explanation:

When solving for x in both equations, we get the same value of x which makes that statement true.

Answer:

It was -∞ < y < ∞

Step-by-step explanation:

None.

The range of the function is ( -∞ to +∞)

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as input and range is all the value that a function can have.

The function is of various types, logarithmic, exponential, quadratic, radical, etc.

The function is shown in the image,

The function is a hyperbolic function, represented by x²/a² -y²/b² = 1 for a hyperbola having a center at the origin.

The function can give any value from the set of real numbers and so,

The range of the function is a set of real numbers.
