What is the distance between (4, 7) and (2,2)?
let's see what to do buddy...
To find the distance between two points, we have the following relation, which is derived from the Pythagorean relation, and we do not need to prove it :
a = ( 2 , 2 ) and b = ( 4 , 7 )
[tex]d = \sqrt{ ( \: {y(b) - y(a)} \: )^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just put the coordinates in the equation :
[tex]d = \sqrt{ ({7 - 2})^{2} + ({4 - 2})^{2} } \\ \: \: \: d = \sqrt{ {5}^{2} + {2}^{2} } \\ d = \sqrt{25 + 4} \\ d = \sqrt{29} [/tex]
So the distance between them equal :
[tex] \sqrt{29} [/tex]
And we're done buddy.
Thanks for watching good luck ♥️♥️♥️♥️♥️.

Simplify:
6x^3 + 5x^2 + 3 - 4 (x^3 - 3x^2 + 2) =6x^3 + 5x^2 + 3 - 4x^3 + 12x^2 - 8 =(6x^3 - 4x^3) + (5x^2 + 12x^2) + (3 - 8) =2x^3 + 17x^2 - 5Option B or second option is correct

Step-by-step explanation:Hi there !
6x³ + 5x² + 3 – 4 (x³ – 3x² + 2) =
= 6x³ + 5x² + 3 - 4x³ + 12x² - 8
= 6x³ - 4x³ + 5x² + 12x² + 3 - 8
= 2x³ + 17x² - 5

Could x = -5 be a solution to the inequality -6 < 3x + 9 < 21?
Answer:
x=−5<x<4Step-by-step explanation:
So you think that x = -5 is the solution for the inequality? Let's check it out.
(Check)
- Substitute x = -5 in the inequality
[tex]-6<3(-5)+9<21\\-6<-15+9<21\\-6<-6<21[/tex]
If it was the symbol ≤ you'd be correct, but it's < so It's a bit wrong.
Now let's solve the inequality. Separate the inequality by parts.
[tex]\left \{ {{-6<3x+9} \atop {3x+9<21}} \right. \\\left \{ {{-6-9<3x} \atop {3x<21-9}} \right. \\\left \{ {{-15<3x} \atop {3x<12}} \right. \\\left \{ {{x>-5} \atop {x<4}} \right.[/tex]
Therefore, the inequality is true only when x > -5 or x < 4.
(Check)
- Substitute x = -4 in the inequality.
[tex]-6<3(-4)+9<21\\-6<-12+9<21\\-6<-3<21[/tex]
The inequality is true for first case.
- Substitute x = 3 in the inequality
[tex]-6<3(3)+9<21\\-6<9+9<21\\-6<18<21[/tex]
The inequality is true for second case.
So the answer for inequality is -5 < x < 4
That means only {-4, -3, -2, ..., 3} can make the inequality true.

12 - 10x + 5x = -18
Answer:
x = 16
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
10*x-5*x-3*x-(12)=0
1.1 Pull out like factors :
2x - 12 = 2 • (x - 6)
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
2.2 Solve : x-6 = 0
Add 6 to both sides of the equation :
x = 6
