which of the following equations are linear?

y=2x - 1/2

y= -1/2x +2

y= -x^2

Step-by-step explanation:

NO and PQ are congruent segments (have the same length), and both have the same midpoint M.

NO ≅ PQ, given.

NM ≅ ½ NO, definition of midpoint.

PM ≅ ½ PQ, definition of midpoint.

PM ≅ ½ NO, substitution.

PM ≅ NM, substitution.

Answer:

the answer is D

Step-by-step explanation:

You would multiply the sales tax (0.06) to the total of the items bought then you would add that to the total amount of the items bought so 34.85+ 2.091 which is the answer of D

Answer:

x-9 yards

Step-by-step explanation:

x (the original position of the football team) -3(3)

so x-9 yards is the answer

Answer:

a. x^2 - 1

b. x^2 - 6x + 9

c. [tex]\dfrac{3x + 1}{x^2 + x}[/tex]

Step-by-step explanation:

a.

(x + 1)(x - 1) =

= x^2 - x + x - 1

= x^2 - 1

b.

(x - 3)^2 =

= (x - 3)(x - 3)

= x^2 - 3x - 3x + 9

= x^2 - 6x + 9

c.

[tex] \dfrac{3 + \frac{1}{x}}{1 + x} = [/tex]

[tex] = \dfrac{x(3 + \frac{1}{x})}{x(1 + x)} [/tex]

[tex] = \dfrac{3x + 1}{x + x^2} [/tex]

[tex] = \dfrac{3x + 1}{x^2 + x} [/tex]

Answer:

Step-by-step explanation:

What..-?

Let's see what to do buddy...

_________________________________

[tex]x - 9y = 17[/tex]

Subtract the sides of the equation minus x

[tex] - 9y = 17 - x[/tex]

Divided the sides of the equation by -9

[tex] \frac{ - 9}{ - 9}y = \frac{17 - x}{ - 9} \\ \\ [/tex]

[tex]y = \frac{ - (17 - x)}{9} \\ [/tex]

[tex]y = \frac{x - 17}{9} \\ [/tex]

Answer: 1/4

Step-by-step explanation:

(Not really sure how to explain it, but there's the answer.)

Answer:

a. 8m

b. 7cm

Step-by-step explanation:

a. Area of a square is s², where s is the side length.

To find s:

s² = 64

s = √64

s = ±8

length cannot be negative, hence it is positive 8

b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.

4s = 28

s = 7

Answer:

3.8 seconds

Step-by-step explanation:

Time taken to sort the mail is [tex]5[/tex] seconds

Let time taken to go from one mailbox to the next be [tex]x[/tex]

Distance between the mailboxes is [tex]100[/tex] ft

So, sorting the mail for one mailbox and going to the next will be done in [tex](5+x)[/tex] seconds

This will happen 19 times and 5 seconds will be needed to sort the mail for the last mail box. The carrier will have to deliver to all the 20 mailboxes in 10 minutes. So, the total time taken will be

[tex]19(5+x)+5=10\times 60\\\Rightarrow 19(5+x)=595\\\Rightarrow 5+x=\dfrac{595}{19}\\\Rightarrow x=\dfrac{595}{19}-5\\\Rightarrow x=\dfrac{500}{19}\ \text{s}[/tex]

Time taken to go from one mailbox to the other is [tex]\dfrac{500}{19}\ \text{s}[/tex]

Speed is given by

[tex]v=\dfrac{100}{\dfrac{500}{19}}\\\Rightarrow v=3.8\ \text{ft/s}[/tex]

The speed at which the carrier has to move from one mailbox to the next is 3.8 seconds.

A number is :

[tex]x[/tex]

_________________________________

Three quarters of it means :

[tex] \frac{3}{4}x \\ [/tex]

_________________________________

Decrease by 20 means :

[tex] \frac{3}{4}x - 20 \\ [/tex]

_________________________________

Equals to 82 means :

[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]

_________________________________

What is that number ?

x asked so we must solve the above equation for x.

Let's do it....

[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]

Plus sides 20

[tex] \frac{3}{4}x = 82 + 20 \\ [/tex]

[tex] \frac{3}{4}x = 102 \\ [/tex]

Multiply sides by 4

[tex]3x = 102 \times 4[/tex]

Divided sides by 3

[tex]x = \frac{102 \times 4}{3} \\ [/tex]

[tex]x = \frac{102}{3} \times 4 \\ [/tex]

Simplify

[tex]x = 34 \times 4[/tex]

[tex]x = 136[/tex]

So that number is 136 .

A and B are alternate interior angles[tex].[/tex]

∴ ∠A = ∠B

➠ (2x - 20)° = 90°

➠ 2x = 90° + 20°

➠ 2x = 110°

➠ x = 110°/2

➠ x = 55°

The value of x for which d || m is 35° and their alternate angles are of equal measure.

A transversal is a line that intersects two lines on the same plane at two different points. When those two intersected lines are parallel their alternate angles, interior angles and exterior angles are equal and the converse of this statement is also true.

We know when two parallel lines are intersected by a transversal their interior alternate angles are equal.

∴ (2x - 20)° = 90°

2x = (90 - 20)°.

2x = 70°.

x = 35°.

Answer:

Step-by-step explanation:

If you try 4 liters, it will overflow since 4 is greater than 3.7854.

The answer is 3 liters.

Answer:

The answer is no solutions.

Step-by-step explanation:

use systems of equations!

first, rewrite both equations so that the sum or difference includes the same variable.

[tex]9-4x=6y\\-4+2x=-3y[/tex]

notice how i made sure the coefficients that have x and y respectively line up.

with this, i can cancel out the x variables by making 2, and -4 as -8 (8+-8=0).

rewrite the equation.

[tex]2(9-4x=6y)\\4(-4+2x=-3y)\\[/tex]

distribute.

[tex]18-8x=12y\\-16+8x=-12y[/tex]

now we can successfully cancel out the x variable!

[tex]18=12y\\-16=-12y[/tex]

uh oh! it seems we can also cancel out the y variables..

[tex]18=0\\-16=0[/tex]

18 is not equal to 0 and neither is -16. because of this, we can conclude there is no solution for this system of equations.
