If lines l and m are parallel, then find the value of y.

Answer:

width = 15 inches

length = 30 inches

Step-by-step explanation:

Let width = w

Length =2w

Perimeter = 90 inches

2*(length + width) = 90

2*(2w +w ) = 90

2* 3w = 90

6w = 90

  w = 90/6

 w = 15 units

length = 2*15 = 30 units

A & D

Step-by-step explanation:

A:

[tex]y = \frac{6}{5} x[/tex]

D:

[tex]y = 4x[/tex]

Answer:

The Equation is in y=mx+b form.

m is 12 and b is 0

Plug in values for x and get coordinates.

At x = 1, y = 12

At x= 2, y = 24

At x = -1, y = -12

At x = -2, y = -24

And so on..

Answer:

[tex] \frac{ \frac{x + 2}{x - 1} }{ \frac{x - 3}{x - 1} } \\ = \frac{x + 2}{x - 1} \times \frac{x - 1}{x - 3} \\ = \frac{x + 2}{x - 3} \: when \: x \ne3[/tex]

Answer:

A

Step-by-step explanation:

A quadratic is 'involving the second and no higher power of an unknown quantity or variable.'

Therefore, we can exclude b and d easily because both have a higher power of 2. 9x^(2) is not a binomial because it only has 1 term (i think its called a term) leaving A, x^2-16x as the only answer left.

Solution:

As we know that f(x) = y

∴ y = f-1(x) ----------> (1)

Given f(x) = 4x

y = 4x

To find the inverse of the f(x), put y for all values of x and x for all values of y.

x = 4y

Divide both sides by 4.

x/4 = y

Using eq (1).

y = 1/ 4x or x / 4

Which represents the inverse of the function f(x) = 4x?

h(x) = x + 4, h(x) = x – 4, h(x) = 3/4 x, h(x) = 1/4 x

Summary:

The equation which represents the inverse of the function f(x) = 4x is h(x) = 1/4 x.

Answer:

  a) 1456/243

  b) 170

Step-by-step explanation:

The sum of n terms of a geometric sequence with first term a1 and common ratio r is given by ...

  Sn = a1·(r^n -1)/(r -1)

__

The first term is 4; the common ratio is 1/3. You want the sum of 6 terms:

  S6 = 4·((1/3)^6 -1)/(1/3 -1) = 4(-728/729)/(-2/3) = 1456/243

__

The first term is -2; the common ratio is -2. You want the sum of 8 terms:

  S8 = -2((-2)^8 -1)/(-2 -1) = -2(255/-3) = 170

Step-by-step explanation:

Step-by-step explanation:

remember, we need to get to an expression of the form

y = ax + b

1.

x + 5y = 5

5y = -x + 5

y = (-1/5)x + 1

2.

3x + 2y = 4

2y = -3x + 4

y = (-3/2)x + 2

3.

2x + y = 4

y = -2x + 4

4.

4x - 2y = 6

2y = 4x - 6

y = 2x - 3

5.

8x - 4y = 16

4y = 8x - 16

y = 2x - 4

6.

3x + 4y = 4

4y = -3x + 4

y = (-3/4)x + 1

7.

9x - 4y = -16

4y = 9x + 16

y = (9/4)x + 4

8.

2x - 5y = 10

5y = 2x - 10

y = (2/5)x - 2

9.

3x + 5y = 10

5y = -3x + 10

y = (-3/5)x + 2

10.

7x - y = 4

y = 7x - 4

Answer:

See below:

Step-by-step explanation:

We can first setup an equation by doing the following:

[tex]4(2-x) = 3(x+1)\\8-4x=3x+3\\8-7x=3\\-7x=3-8\\-7x=-5\\x=-5/-7 (5/7)[/tex]

Whole proccess above!

If you would like an explanation, please let me know so.

Its basically algebra and it's mainly on how you interpret it!

Have a nice day!

Answer:

Yes

Step-by-step explanation:

[tex](f + g)(x) = f(x) + g(x)[/tex]

[tex](f + g)(x) = |x| + 9 + ( - 6)[/tex]

[tex](f + g)(x) = |x| + 3[/tex]

If u graph this function u will realize that the range is :

[tex]y \geqslant 3[/tex]

Thus for all the values of x we have the y which is more than or equal to 3 which is telling us the First option is the correct one.

There u go.....

Answer:i don't know sorry

Step-by-step explanation:

Answer:

The answer is 100.

Step-by-step explanation:

I started with solving 4 divided by 5. It was 0.8. I then started going thru 1 to 10 to 20 to 50 to 100. I was comparing big numbers. I then realized 100+0.8 times 100 = 180!

Answer: [tex]x=100[/tex]

If the equation is [tex]x+\frac45 x = 180[/tex] we add on the LHS: [tex]x(1+\frac45) = 180 \rightarrow x(\frac55+\frac45)= 180\\\frac95 x = 180[/tex]

At this point we divide both sides by 9 and multiply by 5:

[tex]x=\frac 59 (180) = \frac59 (2\times 9 \times 10) = 100[/tex]

Answer:

1

Step-by-step explanation:

Substitute the values for their respective variables.

[tex]\frac{ac}{b^2+1}\\\\\frac{(2)(5)}{(3)^2+1}\\\\\frac{10}{9+1}\\\\\frac{10}{10}\\\\1[/tex]

The given data is,

→ the ratio of cups of water to cups of milk in a recipe is 1 to 5

Now we have to,

→ find three ratios equivalent to the ratio

Then the ratios will be,

→ 1 (×2) : 5 (×2)

= 2 : 10

→ 1 (×3) : 5 (×3)

= 3 : 15

→ 1 (×4) : 5 (×4)

= 4 : 20

Thus, 2 : 10, 3 : 15 & 4 : 20 are the ratios.
