Answer:

2√5

Step-by-step explanation:

Were there answer choices from which to choose? If so, please share them next time.

The Pythagorean Theorem would suit very well in finding this distance.

The horizontal distance between the two points is 2 (I'm neglecting the - sign), and the vertical distance is 4. Thus, the distance between the two points is

d = √ [ 2^2 + 4^2 ] = √ [20] = √4*√5 = 2√5

Which value of the vanable is a solution of the inequality? t<-6<br> 7<br> 6<br> -6<br> -7

oksian1 [2.3K]

Answer:

-7

Step-by-step explanation:

-7 is a solution of the inequality t<-6

By the way, for the number -6, you can think about a temperature below zero. When it is freezing 6 degrees below zero (-6) it is pretty cold.

The question is which number(s) can you substitute for t so that the formula (the inequality) is True.

So let's try for each given value and substitute it for t in t<-6

if you substitute 7 for t you get this:

Is 7 smaller then -6 ?

No that is not true because 7 is bigger then -6.

if you substitute 7 for t you get this:

Is 7 smaller then -6 ?

No that is not true because 7 is much bigger then -6.

if you substitute 6 for t you get this:

Is 6 smaller then -6 ?

No that is not true because 6 is much bigger then -6.

if you substitute -6 for t you get this:

Is -6 smaller then -6 ?

No, that is NOT true because -6 is exactly the same as -6 but NOT smaller then -6...

if you substitute-7 for t you get this:

Please think about temperatures below zero again.

Is -7 colder the -6 ? If so, then the statement is true...

Is -7 smaller then -6 ?

Yes that is true!

So -7 is a solution of the inequality t<-6

Which ordered pair is a solution of the equation? − 4 x + 7 = 2 y − 3 −4x+7=2y−3

Maru [420]

Answer:

The equation is

−4x+7=2y−3

Which can be rewritten as

2y−3 = -4x +7

2y = -4x + 10

y = -2x + 5

The equation represents the line shown in the image below.

Any point that belongs to the line is an ordered pair that represents a solution

To find any ordered pair that satisfies the equation, we place an arbitrary value for x and find the corresponding y value with the equation.

For example

x = 0 ,

y = -2(0) + 5 = 5

(0,5) is an ordered pair

x = 1 ,

y = -2(1) + 5 = 3

(1,3) is an ordered pair

x = 2 ,

y = -2(2) + 5 = 1

(2,1) is an ordered pair

And so on

Which polynomials are in standard form?

tankabanditka [31]

Answer:

A. x^2 + 3x + 2

D. 3x^4 + 4x^3 - 3x^2 - 1

E. 3t^3 + 3t^2 + 2t

Step-by-step explanation:

Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.
