Ummmm so I tried to figure it out but I’m really confused pls help

Given:

The pairs of points are:

a. A(-6,-4), B(-3,-1)

b. C(3.5,1), D(-4,2.5)

c. X(5,-5), Y(-5,5)

To find:

The distance between the pair of points by using the distance formula.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

a.

Using the distance formula, the distance between the points A(-6,-4) and B(-3,-1) is:

[tex]AB=\sqrt{(-3-(-6))^2+((-1-(-4))^2}[/tex]

[tex]AB=\sqrt{(3)^2+(3)^2}[/tex]

[tex]AB=\sqrt{2(3)^2}[/tex]

[tex]AB=3\sqrt{2}[/tex]

[tex]AB\approx 4.2[/tex]

Therefore, the distance between the points A(-6,-4) and B(-3,-1) is about 4.2 units.

b.

Using the distance formula, the distance between the points C(3.5,1) and D(-4,2.5) is:

[tex]CD=\sqrt{(-4-3.5)^2+(2.5-1)^2}[/tex]

[tex]CD=\sqrt{(-7.5)^2+(1.5)^2}[/tex]

[tex]CD=\sqrt{56.25+2.25 }[/tex]

[tex]CD=\sqrt{58.5 }[/tex]

[tex]CD\approx 7.6[/tex]

Therefore, the distance between the points C(3.5,1) and D(-4,2.5) is about 7.6 units.

c.

Using the distance formula, the distance between the points X(5,-5) and Y(-5,5) is:

[tex]XY=\sqrt{(-5-5)^2+(5-(-5))^2}[/tex]

[tex]XY=\sqrt{(-10)^2+(10)^2}[/tex]

[tex]XY=\sqrt{100+100}[/tex]

[tex]XY=\sqrt{200}[/tex]

[tex]XY\approx 14.1[/tex]

Therefore, the distance between the points X(5,-5) and Y(-5,5) is about 14.1 units.

Answer:

Answer:

3.14159... is irrational. Is that what you mean? What you put right now is rational

Step-by-step explanation:

Irrational = infinite

Rational = Not infinite

Answer:

B. X

Step-by-step explanation:

the answer is X because access that is -2/5 and we are looking for 6 2/5 so that means that it has to be that one.

Answer:

I believe B is the correct answer ?

Step-by-step explanation:

Since the is a negative sign already there that turns the -3 into just 3 so the equation turns into 3-6 which is -3 so...

3-6<3.5

Answer:

Quadrant 4 or (IV)

Step-by-step explanation:

Answer:

452.16 in^2

Step-by-step explanation:

multiply 12 times 12

then multiply that number by Pi(3.14)

Answer:

37.68 inches

Step-by-step explanation:

The formula for the circumference of a circle is 2πr.

The radius is 6, and 6⋅2 = 12 (diameter).

3.14 = pi.

12 ⋅ 3.14 = 37.68

Whichever answer is closest to 37.68 is your answer!

Answer: the 2nd box

Step-by-step explanation:

Answer: A = 40°, Angle B = 60° and Angle C = 80°. The angles sum to 180°, so at least one triangle may be drawn.

Answer:

Gonna say B

Step-by-step explanation:

-0.01 (65)+110 = 109.35

It was the predicted value of the 65 year old's vision score.

Since the equation has an equal sign

y (=)

And not more than nor less than, answer choices C and D are eliminated.

The exact value for the 65 year old's vision score is 102. So, A isn't right.

Answer:

Step-by-step explanation:

let me know if this is incorrect

Answer:

The y-intercept of points A and B is -2.

Step-by-step explanation:

Point A is the y-intercept. You can tell by looking at the x and seeing that it is 0. This means the point is the y-intercept.

Hope this helps!

Answer:

-2

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis). To solve this question, first, find the slope, then, plug one of the given points into the equation to isolate b.

1) Find the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (0,-2) and (3,0)

[tex]m=\frac{0-(-2)}{3-0}\\m=\frac{0+2}{3}\\m=\frac{2}{3}[/tex]

Therefore, the slope of of the line is [tex]\frac{2}{3}[/tex]. Plug this into  [tex]y=mx+b[/tex] as m:

[tex]y=\frac{2}{3} x+b[/tex]

2) Find the y-intercept (b)

[tex]y=\frac{2}{3} x+b[/tex]

Plug in one of the given points: (0,-2) or (3,0)

[tex]0=\frac{2}{3} (3)+b\\0=2+b\\b=-2[/tex]

Therefore, the y-intercept of the line AB is -2.

Answer:

46 degrees

Step-by-step explanation:

you know that if you add 134 and x  it will equal a straight line or 180 degrees. So set it up as an addition problem.

134 + x =180   subt. 134 from both sides

x=180-134

x=46 degrees

Answer:

46

Answer:

D) (4, -6)

Step-by-step explanation:

Point C is currently at (2, -5)

The translation is:

(x, y) → (x + 2, y - 1)

New point:

(2, -5) → (x + 2, y - 1)

(4, -6)

Answer:

not a right triangle

Step-by-step explanation:

right triangles are those that prove out to be true when you square the two smaller sides and the sum is equal to the square of the longest side

true or false?

10² + 12² = 14²

100 + 144 = 196

False, ∴ not a right triangle

Answer:

B. x=6

move all terms to the left that don't contain x to the right side and solve.

Answer:

8.94

Step-by-step explanation:

Distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

[tex]d = \sqrt{(3 - (-5))^2 + (2-6)^2}[/tex]

[tex]d = \sqrt{(64 + 16)}[/tex]

[tex]d= \sqrt{80}[/tex]

[tex]d= 8.94[/tex]
