Answer:

x2+y2-x

Step-by-step explanation:

subtract like terms.

The required equivalent expression is [tex]x^2+y^2-x[/tex].

Important information:

The given expression can be written as:

[tex]3x^2+2y^2-3x-2x^2-y^2+2x[/tex]

Combining like terms, we get

[tex](3x^2-2x^2)+(2y^2-y^2)+(-3x+2x)[/tex]

On simplification, we get

[tex]x^2+y^2-x[/tex]

Therefore, the required equivalent expression is [tex]x^2+y^2-x[/tex].

Step-by-step explanation:

For the given similar polygons, the value of x equal to 30.

Two polygons are classified as similar when their angles are congruent and their sides are proportional.

If the polygons of this exercise are similar. You can write:

                                   [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}[/tex]

Then,

                                    [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]

It is possible to note that the scale factor is  [tex]\frac{3}{2}[/tex].  See it.

                                         [tex]\frac{18:6}{12:6}=\frac{3}{2} \\ \\ \frac{21:7}{14:7}=\frac{3}{2}[/tex]

Therefore, you can find x from:

                                      [tex]\frac{18}{12}=\frac{x}{20}\\ \\ 12x=18*20\\ \\ 12x=360\\ \\ x=\frac{360}{12} =30[/tex]

Answer:

Step-by-step explanation:

Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.

So (x+1) and (x-5) are root for the parabola.

y = (x+1)*(x-5)

That is the quadratic equation for Question B.

Back to A, the x-coordinate of vertex of this parabola is at x=2.

This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.

Step-by-step explanation:

To find the answer to -2 - 8, we have to remember that when you subtract numbers, they go towards the negatives. So, since it is -2 - 8, you basically just add together the numbers but keep the negative sign, so the answer would be:

-2 - 8 = -10

Answer:

2 : 4 : 1

Step-by-step explanation:

First take common factors by factorization.

56 = 14 x 4 = 28 x 2

112 = 14 x 8 = 28 x 4

28 = 14 x 2 = 28 x 1

Remove the 28 common factor.

Therefore,

56 : 112 : 28

= 2 : 4 : 1

Range of a function is the extent to which any function may be varied. The range of the given function y= -3sin(x)-4 is [-7,-1].

The range of a function is the extent to which any function may be varied.

We know that the general range of the function of sin(x) is between [-1,1].

-1 ≤ sin(x) ≤ 1. . . . . . . . . .(A)

As our required function is y = -3sin(x) - 4

Now, in order to get this function, we will multiply each side in Equation (A) by -3, therefore,

-3 ≤ -3 sin(x) ≤ 3

Further, subtract from 4 from each side of the equation.

-7 ≥ -3sin(x)-4 ≥ -1

Hence, the range of the given function y= -3sin(x)-4 is [-7,-1].

y = 3x + 2 = 3 * x + 2

point (10 ; 32) on the line ?

so here we can read : x = 10 and y = 32

if x = 10

then y has to be = 3 * 10 + 2 = 30 + 2 = 32

so yes - on the line

The ordered pairs which does not lie on the graph of the function are (8,13).

Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.

The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.

We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.

First ordered pair is (10,32)

32=3*10+2

32=30+2

32=32

It lies on graph.

Second ordered pair is (8,13)

12=3*8+2

12=24+2

12≠26

So it does not lie on graph of function y=3x+2.

Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).
