How do you simplify radical and rational
expressions

Answer:

1

Step-by-step explanation:

y-4=(x-2)

This equation is in point slope form

y-y1 = m(x-x1)

where m is the slope

The slope is 1

y - 4 = x - 2

y = x + 2

Slope-intercept form is y = mx + b, where m is the slope and b is a constant.

Here, m = 1 and b = 2. Therefore, the slope is 1.

Given:

The expression is

[tex]3x^3y+5x^7-4y+x-z+9[/tex]

To find:

The number of variable terms.

Solution:

Constant values, variables, product of constants and variables are known as terms if they are separated by  "+" sign.

The terms which contain atleast one variable is called variable terms.

We have,

[tex]3x^3y+5x^7-4y+x-z+9[/tex]

Here, the terms are [tex]3x^3y,5x^7,-4y,x,-z[/tex] and 9.

All terms contain variables except 9 which is a constant.

Therefore, the number of variable terms is 5.

Hence, your answer was not correct.

Step-by-step explanation:

Answer:

2 over y^3

Step-by-step explanation:

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

P(7,,1) and Q(5,7)

We have

[tex] |PQ| = \sqrt{ ({7 - 5})^{2} + ({1 - 7})^{2} } \\ = \sqrt{ {2}^{2} + ({ - 6})^{2} } \\ = \sqrt{4 + 36 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{40} \: \: \\ = 2 \sqrt{10} \\ = 6.32455532...[/tex]

We have the final answer as

Hope this helps you

Answer:

PQ=1.4 I think

Step-by-step explanation:

y=-4x-8

To find x-intercept / zero , substitute y=0

0=4x-8

Move Variable to the left-hand side and change its sign

-4x=-8

Divide both sides of the equation by -4

Answer: x=2

The answer is choice D because if you subtract 7 from 13 you'll get 6.

Answer:

There are 255 ants in 1 anthill.

Step-by-step explanation:

Do the cross multiplication method. First set the equation as 1275/5 = x/1. Then cross multiply to get 5x = 1275. Divide both sides by 5 to get 255.

Answer:

yes of course you can make a triangle

Answer:

No

Step-by-step explanation:

A triangle has ALL equal sides but since it's 3,8,8 you can't because not all side are equal

(2+4i )+(3-6i)

= 2 + 4i+3 -6i

Answer:

D; 42

Step-by-step explanation:

Step-by-step explanation:

[tex]m = \frac{r - s}{2nr} [/tex]

m(2nr) = r-s

2×n×r×m = r-s

move the r on the right side to the left side

2nrm - r = -s

r ( 2nm - 1 ) = -s

[tex]r \: = \frac{ - s}{(2nm - 1)} [/tex]

Answer:

Alternate angles

Step-by-step explanation:

Alternates angles are in a form of Z so the relationship between angle 12 and 6 are alternate angles.

Answer: x=49

x-17=32

Subtract 17 from both sides.

x=32+17

x=49

Answer:

1/3

Step-by-step explanation:

4/12

2 goes in to 4 and 12, so 4 divide by 2 is 2 and 12 divide by 2 is 6 then you have to simplify it again since 2 can still go into 2 and 6 so 2 divide by 2 is 1 and 6 divide by 2 is 3.

Answer:

Points J, K and Q are collinear

and

There is only one line that can be drawn through points L and P

The true statements are:

Points J, K and Q are collinear.

And, there is only one line that can be drawn through points L and P.

Collinear points are the points that lie on the same straight line or in a single line.

Only one straight line can pass through the two points.

According to the question

We have a diagram in which there are eight points and four lines.

From the given diagram we can see that points J, K and Q lie on the same straight line.

Therefore, points J, K and Q are collinear.

As we know that, only one straight line can pass through the two points.

Therefore, from  two points L and P only one straight line can be drawn.

Hence, statements second and fifth are correct.

Answer:

B

Step-by-step explanation:

I believe the number of sides, and the number of lines of symmetry are the same.

Because, A "regular polygon" has all the same 5 sides all around, which would mean there's the same amount of lines of symmetry.
