Answer:

135

Step-by-step explanation:

I think you mean the LCM instead of LMC. LCM stands for Least Common Multiple. Anyway, some of the multiples of 27 are 27, 54, 81, 108, and 135. Some multiples for 45 are 45, 90, 135. We can see here that 27 and 45 share the mutiple of 135 which is the first number they have in common.

Answer:

I think it's y=5 because it's a horizontal line

Answer and Step-by-step explanation:

Distance is the numerical measurement to find the space or interval between two objects. Distance also refers to physical length. Point x to point y  distance is denoted as |xy|

There are many ways to find out the distance, distance between two objects or two points. The efficient way of finding the distance between two points is given below. Mathematically, the distance between two points on a coordinate plane can be determined by using the distance formula, which is:

                                                 d =√((x2-x1)2+(y2-y1)2),

Where (x1, y1) and (x2, y2) coordinates, and d is the distance.

The middle point between these two points is known as midpoint and can find out by using the formula

Midpoint = a + b /2.

The distance between two points number line can also be calculated by using the formula:

AB =|b –a| or |a-b|.

By what percent does the price change, if the price was $100 and now it is $1250?

-----

x/100 = 1250/100

x = 1250 Percent

tell me if I'm wrong or not:)

Answer:

The price was increased by 1150%

Answer:

y-intercept is 3 and x-intercept is -3/7

Step-by-step explanation:

to find the y-intercept let x = 0 and solve for y.

y=7(0) +3

y=0+3

y=3

to find the x-intercept let y = 0 and solve for x

0 = 7x + 3

-3 = 7x

-3/7 =x

Answer:

C

Step-by-step explanation:

[tex]x^2 + y^2 + 17 = 138\\x^2 + y^2 = 138 - 17\\x^2 + y^2 = 121\\x^2 + y^2 = 11^2\\Radius = 11[/tex]

Answer: 6 cannot go into 3 because it is a larger number but 3 can go into 6 twice because 3x2=6

Answer:

If you can go into fractions 6 can go into 3 half a time, but if you can't do that then say 6 can't go into 3.

Step-by-step explanation:

So, here we know that for 4 avocados it costs $3.79.

First, lets round 3.79 to the nearest whole because even if we don't it will be the same rounded.

We now have $4.00.

What we do now is we look at the rounded cost and the amount of avocados.

So, for 1 avocado it cost 1 dollar.

If we were to do it without rounding it to the nearest whole we would have $1.05.

Answer:

3/4

Step-by-step explanation:

Answer:

560

Step-by-step explanation:

Answer:

Both distances are in the scientific notation:

Earth - Sun = 9.3 * 10^7 miles

Saturn - Sun = 8.87 * 10^8 miles

8.87 * 10^8 - 9.3 * 10^7 =

= 88.7 *10^7 - 9.3 * 10^7 =

= 79.4 * 10^7 = 7.94 * 10 ^8 = 794,000,000 miles

Answer: Saturn is  7.94 * 10^8 miles farther from Sun than Earth is.

Answer:

[tex] x = 15 [/tex]

Step-by-step explanation:

By the Consecutive Interior Angles Converse, if [tex] (3x + 7) + (10x - 22) = 180 [/tex], then y is parallel to z.

Solve for x

[tex] 3x + 7 + 10x - 22 = 180 [/tex]

Combine like terms

[tex] 3x + 10x + 7 - 22 = 180 [/tex]

[tex] 13x - 15 = 180 [/tex]

Add 15 to both sides

[tex] 13x - 15 + 15 = 180 + 15 [/tex]

[tex] 13x = 195 [/tex]

Divide both sides by 13

[tex] \frac{13x}{13} = \frac{195}{13} [/tex]

[tex] x = 15 [/tex]

Answer:

B, because no misleading

Answer:

Step-by-step explanation:

My variables are

d=big number

q=small number

My equations are

6=3q

2d+3=q

I will solve for q in first equation

6/3 = 3q/3

2=q

Now I will pluck back in to get d

2d+3=(2)

   -3   -3

2d=-1

2d/2=-½

d=-1/4

So the solution is

(-1/4, .2)

Answer:

sorry I don't no the answer

Answer:

Supplementary angles

Step-by-step explanation:

These are angles adding up to 180 when put together and they are normally on a straight line.

Step-by-step explanation:

Answer:

n-4=-15

Step-by-step explanation:

Answer:

y = -1/3x - 2

Step-by-step explanation:

We can use the points (-1, -1) and (5, -3) to solve.

Slope formula is y2-y1/x2-x1

-3-(-1)/5-(-1)

-2/6

-1/3

Find the y intercept.

y = -1/3x + b

-1 = -1/3(-1) + b

-1 = 1 + b

-2 = b

y = -1/3x - 2

Answer and Step-by-step explanation:

Let bold r 1 comma ... Comma bold r subscript p be vectors in the set of real numbers r superscript n:

r1,… ,rp be vector in Rn

And let Q be an m times n matrix = Q= m x n

write the matrix left bracket upper q bold r 1 ...Q bold r subscript p right bracket as a product of two matrices = [Qr1, …, QrP], which is a product of two matrices.

To write the product of two matrices.

Use the definition of AB in reverse order:

[Qr1, …, QrP] = Q [r1, …, rp]

                       = QR

Answer:

[tex]P(x)=x^5+11x^3+28x[/tex]

Step-by-step explanation:

Roots of a polynomial

If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula

[tex]P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)[/tex]

Where a is an arbitrary constant.

We know three of the roots of the degree-5 polynomial are:

[tex]x_1=0;\ x_2=\sqrt{7}\boldsymbol{i}:\ x_3=-2\boldsymbol{i}[/tex]

We can complete the two remaining roots by knowing the complex roots in a polynomial with real coefficients, always come paired with their conjugates. This means that the fourth and fifth roots are:

[tex]x_4=-\sqrt{7}\boldsymbol{i}:\ x_3=+2\boldsymbol{i}[/tex]

Let's build up the polynomial, assuming a=1:

[tex]P(x)=(x-0)(x-\sqrt{7}\boldsymbol{i})(x+\sqrt{7}\boldsymbol{i})(x-2\boldsymbol{i})(x+2\boldsymbol{i})[/tex]

Since:

[tex](a+b\boldsymbol{i})\cdot (a-b\boldsymbol{i})=a^2+b^2[/tex]

[tex]P(x)=(x)(x^2+7)(x^2+4)[/tex]

Operating the last two factors:

[tex]P(x)=(x)(x^4+11x^2+28)[/tex]

Operating, we have the required polynomial:

[tex]\boxed{P(x)=x^5+11x^3+28x}[/tex]
