Step-by-step explanation:

when x = -1

y= 3x - 1

3(-1) - 1

-3 -1

-4

when x = 0

y = 3x - 1

3(0) - 1

0 - 1

-1

when x = 2

y = 3x -1

3(2) - 1

6 - 1

5

Step-by-step explanation:

[tex]y = 3x - 1[/tex]

Putting x = -1

[tex]y = 3( - 1) - 1[/tex]

[tex]y = - 3 - 1[/tex]

[tex]y = - 4[/tex]

Putting x = 0

[tex]y = 3(0) - 1[/tex]

[tex]y = 0- 1[/tex]

[tex]y = -1[/tex]

Putting x = 2

[tex]y = 3(2) - 1[/tex]

[tex]y = 6 - 1[/tex]

[tex]y = 5[/tex]

Answer: Choice B

[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]

===============================================================

Explanation:

Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is

c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)

This represents the length of the vector <-4,7>

Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.

The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

Answer:

heliocentric = sun is center

geocentric = earth is center

Answer:

Heliocentric Theory goes with 2.

Geocentric Theory  goes with 1.

Step-by-step explanation:

The Heliocentric theory is the theory that the Sun is the center of the solar system. Hence, the prefix "helio" which means "relating to the sun"

The Geocentric theory is the theory that the earth is the center of the solar system. Hence, the prefix "geo" which means earth.

A good way to remember which is which is to remember the prefixes.

Answer and Step-by-step explanation:

To find the GCF (Greatest Common Factor), you need to see what all of the numbers have in common.

By looking at the terms in the expression, we can see that all the numbers are divisible by 4, so lets factor that out.

[tex]4(23x^7y^5+24x^5y^4+11x^4y^5)[/tex]

We can also see that the terms have a [tex]x^4[/tex] and [tex]y^4[/tex] in common, so factors those out.

[tex]4x^4y^4(23x^3y+24x+11y)[/tex] <- This is the answer.

Answer:

1007

Step-by-step explanation:

Divide the expression by two parts: the first one with all positive integer (the integer which can't be divided by two), 1+3+5+...2013 and the rest -2-4-6-...-2012

If you notice both parts are arithmetical sequences

Explore the first one 1+3+5...+2013

a1=1 d=3-1=2 an=2013

a1+d(n-1)=an

1+2(n-1)=2013

2(n-1)=2012

n-1=1006

n=1007

Sn=( 1/2)*(a1+an)*n= 0.5*2014*1007=1007*1007=1014049

-2+(-4)-...-2012

a1=-2

d=a2-a1= -4-(-2)=-2

a1+d(n-1)=an

-2+(-2)(n-1)=-2012

n=1006

Sn= (a1+an)/2*n=(-2-2012)/2*1006=-1007*1006

-1007*1006+1007*1007= 1007- the answer

The second mean

1-2=-1

3-4=-1

5-6=-1

There are 2012/2=1006 couples and every of them has sum -1

-1*1006=-1006

-1006+2013=1007

Answer:

18....I hope thats righ

Step-by-step explanation:

Answer:

a. 62

Step-by-step explanation:

use the Bodmas method

=3×9-5+20×2

=62

The value of the expression {[3 x (3+6) - 5] + 20 x 2 will be 62. so option A is correct.

We can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

So, use the Bodmas method

=[3 × 9 - 5 ]+ 20 × 2

= [27 -5] + 40

= 22 + 40

=62

Therefore,  the value of the expression {[3 x (3+6) - 5] + 20 x 2 will be 62. so option A is correct.
