Answer:

The answer is 12 markers. 4 markers for $7. You multiply 7 x 3and you end up with 21

Step-by-step explanation:

Step-by-step explanation:

Reflecting across the x axis will result in a sign change for. the y component, therefore (-7,-9) becomes (-7,9)

Reflecting across the y axis will result in a sign change for the x component, therefore (-7,-9) becomes (7,-9)

Answer:

6  1/3 or 6.333333. . .

Step-by-step explanation:

Original Equation:

2(y - 4) + 4y = 11 + 3y

Use distributive property.

2 x y = 2y

2 x (-4) = -8

Plug these values back into the equation:

2y - 8 + 4y = 11 + 3y

Add 8 to both sides

2y + 4y = 19 + 3y

Add 2y and 4y together

6y = 19 + 3y

Subtract 3y from both sides

3y = 19

Divide both sides by 3

6.3333333333333333333. . . . .

6 1/3

Answer:

The first riddle is Age. Some people love their age, some people hate their age. Age can change appearances and thoughts because as you mature you view things differently. If you take care of yourself, you will become die older than most people. Some people are fooled by age, they think someone is older or younger than they really are. Some people don't know someone's age, so it is a mystery. Some people try and hide their age. Age never decreases.

The second riddle is a shadow. A shadow is only one color, but it can be any shape or size. Shadows are stuck at the bottom, but it easily moves. Shadows appear in the sun, but not when it is raining because of the clouds. Shadows do no harm, and they can't feel anything.

It's -7

Step-by-step explanation:

Answer:

y = - 4x + 13

Step-by-step explanation:

In order to do this problem you would need a whole new equation, but you will use what is given to you:

instead of going with:

x - 4y = 20

Turn it into y = mx + b form, also known as slope-intercept form:

x - 4y = 20

-x       = -x

_________

- 4y = 20 - x

Then divide both sides by - 4:

[tex]\frac{-4y}{-4} = \frac{-x + 20}{-4}[/tex]

You will then get:

y = [tex]\frac{1}{4}x - 5[/tex]

From this equation we will only need the slope!

m || = [tex]\frac{1}{4}[/tex]

(This slope is for parallel)

but if you want perpendicular to the slope, then we need the negative reciprocal!

Negative reciprocal is a flipped version of the value that is negative, for example:

2 = [tex]-\frac{1}{2}[/tex]

Because [tex]\frac{2}{1}[/tex] = 2

Now we will find the perpendicular slope which is:

m ⊥ = - 4

Now substitute this slope into slope intercept form:

y = mx + b

(-3) = -4(4) + b

(Take away parentheses)

-3 = -16 + b

(Move - 3 to the other side, by making it positive, but what you do to one side, you do to the other)

= -13 + 6

(Move - 13 to the other side, by make - 13 into +13)

+13 = +13

________

13 = b

(This is you b, also known as you intercept)

Your answer is:

y = -4x + 13

Answer:

4

Step-by-step explanation:

Known:

Every week Hannah's office recyles 2 kilograms of paper

1 week = 2 kg of paper

To find a rate at which the office recyles paper divide the unit of measurement (kg) by a unit of time (weeks)

So:

2 kg/ 1 week = 2 kg of paper recycled per week

We want to know how many weeks it will take to recycle 8 kg.

Think of it this way.

if you divide kg by kg/week the kg cancel out and you get the unit week.

So divided 8 kg by the rate we discovered (2 kg/week) and you shall get the answer 4 weeks.

Answer:

so if Thomas payed $40 for the bus we have to find what he payed not including the $40 bus fee.

so we have to subtract 40 from the total price of $104.40.

the equation is 104.40-40=?

104.40-40=$64.40 payed outside the bus fee.

now we have to figure out how many times .70 fits into 64.40

the equation would be 64.40/.70 which means we are dividing 64.40 by .70

so 64.40/.70=92

Thomas and his friends traveled a total of 92 miles to go to the concert.

Answer:

(-16 , -4)

Step-by-step explanation:

you use rise over run

the rise is your y

the run is the x

[tex]\frac{y2-y1}{x2-x1}[/tex]⇒[tex]\frac{-3-1}{-24-(-8)}[/tex] =

[tex]\frac{-4}{-16}[/tex] or (-16, -4)

Answer:

The answer is x=86

Step-by-step explanation:

1st set up an equation

2nd combine like term i.e, 104 and -10

3rd isolate x; you would do this by subtracting 94 on both sides of the equation

You're final answer is x=86

Answer:

27 - 5n

Step-by-step explanation:

n times 5 (5n) - 27

Answer:

rate of change

Step-by-step explanation:

Answer:

"rise over run" or "rate of change"

Step-by-step explanation:

"Slope" itself is "rise over run", or how quickly the line moves up or down relative to the x-axis as the value of x changes.

A gradient is really just another name for slope, not a description OF a slope.

Answer:

Parallel lines have the same slope, while perpendicular lines have completely opposite slopes. So a line has a slope of 2, a parallel line would have a slope of 2, and a perpendicular line would have a slope of -1/2. The easiest form to identify the slope is standard form because it shows the slope within the equation with out having to solve the equation or convert it into another form.
