Simplify the following.
-(3x)2

Answer:

[tex]\huge\boxed{\tt{x = 11 , y = 1}}[/tex]

Step-by-step explanation:

x + y = 12 -------------------------(1)

2x + 5y = 27 --------------------(2)

Multiply (1) by 2

2(x+y) = 12 * 2

2x + 2y = 24 --------------------(3)

Subtract (3) from (2)

2x + 5y - ( 2x + 2y ) = 27 - 24

2x + 5y - 2x - 2y = 3

5y - 2y = 3

3y = 3

Divide 3 to both sides

y = 1

Put y = 1 in (1)

x + 1 = 12

x = 12 - 1

x = 11

So,

x = 11 , y = 1

[tex]3:5[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that:\\AB\ is\ a\ Line\ Segment\ that\ has\ Points\ A\ and\ B,\ that\ are\ it's\ two\ End-Points.\\Now,\\Point\ C\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AC\ and\ CB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:2.\\\\Point\ E\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AE\ and\ EB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:3.\\\\Point\ D\ is\ marked\ on\ AB\ that\ divides\ AB\ into\ AD\ and\ DB,\ whose\\ lengths\ are\ in\ a\ Ratio\ 1:4.\\\\[/tex]

[tex]Now,\\For\ Point\ C,\\Total\ no.\ of\ parts=1+2=3\\Length\ of\ AC=\frac{1}{3}x\\Length\ of\ CB=\frac{2}{3}x\\\\For\ Point\ E,\\Total\ no.\ of\ parts=1+3=4\\Length\ of\ AE=\frac{1}{4}x\\Length\ of\ EB=\frac{3}{4}x\\\\For\ Point\ D,\\Total\ no.\ of\ parts=1+4=5\\Length\ of\ AD=\frac{1}{5}x\\Length\ of\ DB=\frac{4}{5}x\\[/tex]

[tex]Now,\\Lets\ move\ onto\ some\ REAL\ calculations!!\\We\ firstly\ observe\ that,\\AD+DC=AC\\Hence,\\\frac{1}{5}x+DC=\frac{1}{3}x\\DC=\frac{1}{3}x-\frac{1}{5}x\\DC=\frac{5-3}{15}=\frac{2}{15}[/tex]

[tex]We\ secondly\ observe\ that,\\AD+DE=AE\\Hence,\\\frac{1}{5}x+DE=\frac{1}{4}x\\DE=\frac{1}{4}x-\frac{1}{5}x\\DE=\frac{5-4}{20}=\frac{1}{20}[/tex]

[tex]Now,\\We\ know\ that,\\DE+EC=DC\\Hence,\\\frac{1}{20}x+EC=\frac{2}{15}x \\EC=\frac{2}{15}x-\frac{1}{20}x\\EC=\frac{40-15}{300}x\\EC=\frac{25}{300}x=\frac{1}{12}x\\\\By\ comparing\ DE\ and\ EC,\\Length\ of\ DE=\frac{1}{20}x\\Length\ of\ EC=\frac{1}{12}x\\The\ ratio\ of\ Lengths\ of\ DE\ to\ Length\ of\ EC=\frac{1}{20}x:\frac{1}{12}x\\We\ know\ that,\\Ratio's\ are\ merely\ fractions\ represented\ by\ ':'.\\Hence,\\\frac{1}{20}x:\frac{1}{12}x\\=\frac{\frac{1}{20}x}{\frac{1}{12}x}\\[/tex]

Answer:

x = -3

Step-by-step explanation:

Answer:

x=-3

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

The axis of the symmetry will be shifted 2 units to the right.

A parabola is a two dimensional figure on a plane which is U shaped and any point on the parabola is at an equal distance from a fixed point called focus and a fixed line called directrix.

The axis of symmetry of a parabola is the line which passes through the vertex of the parabola and divides the parabola in to two equal halves.

If the parabola is opening upward, then the axis of symmetry will be a vertical line passing through x = h, where h is the x coordinate of the vertex.

When the parabola is shifted 2 units to the right, then the x coordinate of the vertex changes to h + 2.

So the new axis of symmetry will be x = h + 2.

So the axis of symmetry is shifted 2 units to the right.

There will be no effect that the parabola moves 3 units down. The axis of symmetry will be the same.

Hence the axis of the symmetry will be shifted 2 units to the right.

Answer:

The first answer.

Step-by-step explanation:

First of all, the circle on -3 did not have filling so that means it is not equal to z. Then we look on the circle on 6. It does have a filling which means it is equal to and greater than z. Now we look in between -3 and 6. Is there any white spots? If no, then we don’t have to use an OR. Therefore, the first answer is the only plausible answer.

Answer:

Step-by-step explanation:To find the scale factor of an original and a scale drawing, set up a ratio of the original length and the length of the drawing. Then simplify the ratio. A scale factor may be expressed by the ratio or by a positive number.A scale factor expresses the relationship between two lengths. It can be expressed as a ratio or a positive number. Let's look at some examples. If the original image is 4 inches, and the scale drawing is 8 inches, we can say that the scale factor is 4:8, but we must simplify that ratio, making it 1:2. We can also write the scale factor as a number by dividing 8 by 4 for a scale factor of 2.

That example is pretty straightforward, but let's look at something a bit more complicated. Let's say we have an original image that is 4 inches and a scale drawing that is 9.5 inches, and we want to find the scale factor. We cannot write the ratio 4:9.5, because ratios do not allow decimals or fractions. We must simplify the ratio. This involves getting rid of the decimal. To do this, we multiply 9.5 by 2 and get 19. What we do to one element of the ratio, we must do to the other, so we multiply 4 by 2 for 8. Our ratio looks like this: 8:19. Because 19 is a prime number, we cannot simplify further. This scale factor of 8:19, then, tells us that for every 8 inches in the original, the scale drawing will have 19 inches. We can also express the scale factor as 2.375 (19 divided by 8).

We'll try one more example. We have an original image that is 1.25 inches and a scale drawing that is 4 inches. Again, we cannot write a ratio with decimals, so we can't leave our scale factor as 1.25:4. We must simplify. This time, we must get rid of the decimal by multiplying each side by 4, so we have 5:16. We cannot simplify this ratio any further, but we can express it by the number 3.2 (16 divided by 5).

Monomial examples

A monomial is an expression in algebra that contains one term, like 3xy. Monomials include: numbers, whole numbers and variables that are multiplied together, and variables that are multiplied together. Any number, all by itself, is a monomial, like 5 or 2,700.

Step-by-step explanation:

Since, both the events are independent.

So, P(A+B) = P(A)×P(B)

a) P( Head & Getting a 2 ) = P( head ) × P( Getting a 2 )

[tex]=\dfrac{1}{2}\times \dfrac{1}{6}\\\\=\dfrac{1}{12}[/tex]

b) P( Even number & Tail ) = P( Even number ) × P( Tail )

[tex]=\dfrac{3}{6}\times \dfrac{1}{2}\\\\= \dfrac{1}{4}[/tex]

Answer:

Area: 38.48u²   Perimeter: 24.995u

Step-by-step explanation:

This is a quarter of a circle. You can use the formula to find the area of a full circle and then divide it by 4 to find the area of a quarter circle.

The radius is 7. So..

A = πr²/4 = π × 7²/4

= π × 49/4

= 12.25π

≈ 38.48u²

You have to find the circumference of the full circle in order to find the perimeter of this shape. The circumference is πd.

To find the diameter of a circle you multiply the radius by 2.

7 × 2 = 14

P = π14

≈ 43.98

Then, you divide that number by 4 because the arc (the curved part) is a quarter of the circumference.

43. 98 ÷ 4 = 10.995 - This is the length of the arc.

Now you add all the measurements:

7 + 7 + 10.995 = 24.995u
