Answer:

one whole number two over fifteen or in decimal 1.1333

Step-by-step explanation:

this mathematics is very by explanations ,

Firstly, look for the LCM of the in the denominators ,that is look for the LCM of 3,15,5 which is 15 then a straight line keep the denominators result from the LCM under the straight line then use the denominators to divide 15 and multiply with numerators and then add the results and then you divide it by 15 and the result is 17 then 17/15 then you have one whole number,two over fifteen

Answer:

[tex]x^2-6x+9[/tex]

Step-by-step explanation:

Say you have a function [tex]f(x)=x+1[/tex]. If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get [tex]f(3)=3+1=4.[/tex] When combining functions, you should do the same thing.

Here, we have [tex]f(x)=x^2.[/tex] We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). [tex]g(x)=x-3.[/tex] So, f(g(x)) would equal [tex](x-3)^2[/tex], which equals [tex]x^2-6x+9[/tex].

Answer:

see below

Step-by-step explanation:

We can use the distance formula

11. d =sqrt( (y2-y1)^2 + (x2-x1) ^2)

  = sqrt( (-3 --5)^2+(-6 - -1)^2)

  = sqrt( (-3+5)^2 + (-6+1)^2)

  = sqrt( 2^2 + (-5)^2)

  = sqrt (4+25)

  = sqrt(29)

12. Using the points ( 1,3) and (4,-1)

d =sqrt( (y2-y1)^2 + (x2-x1) ^2)

  = sqrt( (-1-3)^2+(4-1)^2)

  = sqrt( (-4)^2+(3)^2)

 = sqrt(16+9)

 =sqrt(25)

 =5

Answer:

11. d =sqrt( (y2-y1)^2 + (x2-x1) ^2)

 = sqrt( (-3 --5)^2+(-6 - -1)^2)

 = sqrt( (-3+5)^2 + (-6+1)^2)

 = sqrt( 2^2 + (-5)^2)

 = sqrt (4+25)

 = sqrt(29)

12. Using the points ( 1,3) and (4,-1)

d =sqrt( (y2-y1)^2 + (x2-x1) ^2)

 = sqrt( (-1-3)^2+(4-1)^2)

 = sqrt( (-4)^2+(3)^2)

= sqrt(16+9)

=sqrt(25)

=5

Answer:

X=4-9

Step-by-step explanation:

Answer:

{4,5,6,7,8,9}

Step-by-step explanation:

if we talk about math ,then x is a set which contains integers from 4 to 9.

Answer:

42 and 22 are the numbers

Step-by-step explanation:

Let the numbers be x and y

[tex]x + y = 64[/tex]

[tex]x - y = 20[/tex]

On adding both

[tex]x + y + x - y = 64 + 20[/tex]

[tex]2x = 84[/tex]

[tex]x = \dfrac{84}{2} [/tex]

[tex]x = 42[/tex]

Using 1

[tex]42 + y = 64[/tex]

[tex]y = 64 - 42[/tex]

[tex]y = 22[/tex]

The measure of side BC is 30 units.

Given:

Points A, B, and C are collinear and B lies between A and C.

[tex]AC=48[/tex]

[tex]AB=2x+2[/tex]

[tex]BC=3x+6[/tex]

To find:

The value of BC.

Solution:

Points A, B, and C are collinear and B lies between A and C. So,

[tex]AB+BC=AC[/tex]              [Segment addition postulate]

[tex](2x+2)+(3x+6)=48[/tex]

[tex]5x+8=48[/tex]

Subtract 8 from both sides.

[tex]5x=48-8[/tex]

[tex]5x=40[/tex]

Divide both sides by 5.

[tex]\dfrac{5x}{5}=\dfrac{40}{5}[/tex]

[tex]x=8[/tex]

Now,

[tex]BC=3(8)+6[/tex]

[tex]BC=24+6[/tex]

[tex]BC=30[/tex]

Therefore, the value of BC is 30.

The possible coordinates for G are -11 and 5.

Given:

On a number line, suppose point E has a coordinate of [tex]-3[/tex], and [tex]EG=8[/tex].

To find:

The possible coordinates of point G.

Solution:

Either point G lies 8 units left of point E or 8 units right of point E.

[tex]G=-3-8[/tex]

[tex]G=-11[/tex]

And

[tex]G=-3+8[/tex]

[tex]G=5[/tex]

Therefore, the possible coordinates for G are -11 and 5.

The equivalent expression of the given value is 4.1 m/s in two significant figures

Your question is incomplete, i believe the following is the intended question.

[tex]\frac{450 \ m}{ 110 \ s}[/tex] equals which of the following values to the correct number of significant figures ?

The express the given value in the correct significant figures we will simplify it as follows:

450 m has 2 significant figures ( 4 and 5)

110 s has 2 significant figures (1 and 1)

Thus, the resultant ratio of the two numbers will be expressed in two significant figures.

[tex]\frac{450 \ m}{110 \ s} = 4.0909 \ m/s\\\\in \ two \ significant \ figures = 4.1 \ m/s[/tex]

Therefore, the equivalent expression of the given value is 4.1 m/s

Answer:

  (b)  domain: all reals; range: y ≤ 6

Step-by-step explanation:

The domain of any polynomial function is always "all real numbers." There are no values of the variable for which a polynomial is undefined.

The range of a polynomial will depend on its degree and the sign of the leading coefficient. Here, the degree is even, so the range has a limit. The leading coefficient is negative, so that limit is a maximum.

Only one answer choice has these characteristics:

  domain: all real numbers; range: y ≤ 6

The graph confirms this choice of range.
