4+(7*8)=x

x= 60

Step-by-step explanation:

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:

y = (x - 4)(x + 2)

Step-by-step explanation:

Quadratic Formula:

Substitute 1 for a, -2 for b, and -8 - y for c in the quadratic formula.

Answer:

[tex]y= (x-4)(x+2)[/tex]

Step-by-step explanation:

To factor polynomials you have to use FOIL. Which stands for First, Outer, Inner, and Last. This means that you have to multiply the first numbers of each part by each other, the outer two between both parts, the inner two between both parts, and the last two of each part, respectively. Then, you would simplify. If you go and do this for each answer choice, the last one would be the only correct one.

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!

[tex]\frac{33}{7}[/tex]

Step-by-step explanation:

[tex]7[/tex]×[tex]4=28[/tex]

[tex]28+5=33[/tex]

Thus, it becomes [tex]\frac{33}{7}[/tex]

Answer:

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.

I hope this helps!

Answer:

D) (4, -6)

Step-by-step explanation:

Point C is currently at (2, -5)

The translation is:

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:

8.239x10^-5

so the answer is A

Step-by-step explanation:

trust me

ps. use photomath on phone

Write both number with the same power of 10, factor out that power of 10 (since it's common to both terms), then simplify to standard scientific notation (that is, a.bcd... × 10⁻ⁿ):

(8.28 × 10⁻⁵) - (4.1 × 10⁻⁷) = (828 × 10⁻⁷) - (4.1 × 10⁻⁷)

… = (828 - 4.1) × 10⁻⁷

… = 823.9 × 10⁻⁷

… = 8.239 × 10⁻⁵
