What is the value of the expression 3x-8y when x=10 and y=2?

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

same reasoning for the rest

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).

I'm not sure how I can show you because you have to plot the points, not give a straight answer but I'll give you an idea.

Step-by-step explanation:

POINT 1: For the first point you are going to find 4 on the X axis and go up by 3. Plot your point there

POINT 2: Find the number 2 on the X axis and go up by 6

BTW keep in mind that the X axis is the the horizontal line that divides the coordinate plane half. If you folllow my intrustions for the first 2 points, you'll get an idea of how to grph the 3rd point!

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

Answer:

40

Step-by-step explanation:

In word problems, the word "of" usually means multiply.  Thus, for example, 10% of $50 is $5.  This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply:    (1/10)(50) = 5

So, we often see equations like:

    R = (1/2)D        meaning R is 50% of D, or R is half of D

Let x = the number we want to find

This problem says:

 "12 is 30%       of    what number?"

  12 = (30/100) *        x

12 = (3/10)x

(10/3)12 = x             [multiply both sides by (10/3)]

    40 = x        

Checking (very important):      

 Is   12 = (3/10)(40)    ?

       12 = (3)(4)    ?

       12 = 12     ? yes

Answer:

40

Step-by-step explanation:

Let x = unknown number

30% = 30/100 = 0.3

If 12 is 30% of x, then

   30% of x is 12

⇒ 0.3x = 12

⇒ x = 12 ÷ 0.3

⇒ x = 40

Or, you can divide 12 by 3 to get 10% and then multiply this by 10 to get 100%:

12 ÷ 3 = 4 (so 4 is 10%)

4 × 10 = 40 (which is 100%)

The fourth and fifth term of this sequence is -30 and -10 respectively.

The common difference in a geometric progression is the ratio between two successive terms.

Let's find the common difference in this sequence

[tex]r = \frac{-270}{-810} \\r = \frac{1}{3}[/tex]

The nth term of a geometric sequence is given as

[tex]T_n = ar^n^-^1\\[/tex]

The next two terms of this sequence will be 4th and 5th term.

The fourth term of this sequence is

[tex]T_4 = ar^4^-^1\\T_4 = -810 * (\frac{1}{3})^3\\ T_4 = -810 * \frac{1}{27}\\ T_4 = -30[/tex]

The fifth term of this sequence is

[tex]T_5 = ar^5^-^1\\T_5 = -810 * (\frac{1}{3})^4\\T_5 = -810 * \frac{1}{81} \\T_5 = -10[/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.

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].
