An equlateral triangle has sides of length 2x-3 each. The perimeter of the triangle is 63 cm. Find the value of x

The parent function is y = x²

If we vertically stretch it by a factor of 3, then we get to y = 3x²

So it's 3 times taller than it used to be. A point like (2,4) moves to (2,12) after applying this vertical stretch. Because it's stretched vertically, it becomes more narrow in the horizontal direction.

If we then shift that down by 2 units, then we arrive at the equation y = 3x²-2

So to summarize, we applied these two transformations:

Answer:

B.

Step-by-step explanation:

For reference, the median for housecats is 11 and the median for small dogs is 9. So, by process of elimination, B is the correct answer.

The dot plot is solved and Overall, house cats weigh more with less variation.

A dot plot, also known as a dot chart or dot graph, is a type of data visualization that displays the frequency of values in a dataset. It is a simple graphing technique that uses dots to represent data points on a horizontal or vertical axis.

Each data point in the dataset is represented by a dot placed above the corresponding value on the axis. If there are multiple data points with the same value, the dots are stacked vertically above that value. The resulting plot shows the distribution of data points along the axis, with the height of the stack of dots representing the frequency of each value.

Given data ,

Let the dot plot be represented as A and B

where the weights of house dogs and small dogs are plotted

Now , the median of house cats = 11

The median of small dogs = 9

Variation refers to the spread or dispersion of a set of data points. It measures how much the values in a dataset differ from the mean or from each other. There are several ways to calculate variation, including the range, variance, and standard deviation.

So , Overall, house cats weigh more with less variation.

Hence , the dot plot is solved

For a 2 step equation, I'm guessing you are talking about this kind of equations.

2x+3=5

In these equations you solve it first.

2x=2

x=1

Now to check your work you simply substitute it back in to see if the equation stands.

2*1+3=?=5

2+3=5

This equal sign stands when I substitute it back so therefore its correct.

That's what checking your work means, this is how you check your work for most solve for x problems :)

Answer:

  13 in by 51 in

Step-by-step explanation:

The area is the product of the dimensions, so is ...

  663 = x(4x -1)

  4x^2 -x -663 = 0 . . . . . . subtract 663 to put in standard form

Using the quadratic formula, we can find the solutions.

  x = (-(-1) ±√((-1)^2 -4(4)(-663)))/(2(4))

  x = (1 ± √10609)/8 = (1 ±103)/8

Only the positive solution is of any use in this problem, so ...

  x = 104/8 = 13

  4x-1 = 4(13)-1 = 51

The dimensions of the rectangle are 13 inches by 51 inches.

2✓3

Step-by-step explanation:

it's a special triangle, so just take 6 divided by ✓3 and you'll get 2✓3.

Answer:

Step-by-step explanation:

So you know that distance = rate x time.

9 miles in 1.5 hours

In this case, you know the time (1.5 hours) and the distance (9 miles)

(You can ignore the rest of the chart since the question is just about running.)

What's missing is the rate (r) at which you ran. (Think of it as speed...)

If r x t = d, that means that d ÷ t = r

So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...

6

So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!

Answer: j= −17 /3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3j−2+7=−12

3j+−2+7=−12

(3j)+(−2+7)=−12(Combine Like Terms)

3j+5=−12

3j+5=−12

Step 2: Subtract 5 from both sides.

3j+5−5=−12−5

3j=−17

Step 3: Divide both sides by 3.

3j /3 = −17 /3

j= −17 /3

Answer:

$16,875

Step-by-step explanation:

so we must take all of those to get how much fencing we need in total so we add all of those numbers leaving us with 1875 ft of fencing we need.

so if fencing costs $27 per yard we need to change the units

so there are 3 feet per yard so we divide 1875 by 3 leaving us with 625 yards of fencing

so now we multiply the 625 yards of fencing by the $27 per yard leaving us with $16,875 in total to spend for this farmer to fence his pasture for the horses

Step-by-step explanation:

Answer:

Martin's Bowling cost = $5x

Isabelle Bowling cost = $5x + 3

where x is the total games Martin and Isabelle played.

Step-by-step explanation:

As given,

There are 2 people - Martin and Isabelle

Each game costs = $10

Let they both play total games = x

⇒total game cost = $10x

As they split the cost , it means the cost is divided into half

⇒Martin game cost = $5x

Isabelle game cost = $5x

Also, given that Isabelle pays $3 to rent shoes.

⇒$3 is added to the Isabelle game cost

∴ we get

Isabelle game cost = $5x + 3

so, we get

Martin's Bowling cost = $5x

Isabelle Bowling cost = $5x + 3

Answer:

a minimum of $1,200

Step-by-step explanation:

The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.

Answer:

Acceleration, [tex]a=4\ m/s^2[/tex]

Step-by-step explanation:

Given that,

Initial speed = 4 m/s at 2 seconds

Final speed = 32 m/s at 9 seconds

We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,

[tex]a=\dfrac{v_2-v_1}{t_2-t_1}\\\\=\dfrac{32-4}{9-2}\\\\=\dfrac{28}{7}\\\\=4\ m/s^2[/tex]

So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].
