Find the midpoint between points F(-5, -18) and K(15,8).

Answers

Answer 1

Answer:

(5,-5)

Step-by-step explanation:

Answer 2
to find this out you would add them together and then divide by two:

(-5)+15= 10
10/2=5

(-18)+8=(-10)
-10/2=5

so your points would be 5,-5. you would add your x values and divide it by two and then your y values and divide them by two

From the equation y−3=−2(x+1), identify the slope and a point on the line.

Answers

Answer:

slope = - 2, point on line = (- 1, 3 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 2(x + 1) ← is in point- slope form

with slope m = - 2 and (a, b ) = (- 1, 3 )

The slope of equation y−3=−2(x+1) is -2.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y−3=−2(x+1)

Using Slope- Intercept form

y= mx + b

So, the slope for the equation is -2.

Hence, the slope is -2.

What is the difference x/x^2+3+2 - 1/(x+2)(x+1)

Answers

Answer:

#4,   x-1/(x^2+3x+2)

Step-by-step explanation:

x/(x^2+3x+2) - 1/((x+2)(x+1))

Convert the 1/((x+2)(x+1)) to 1/(x^2+3x+2)

now you have a common denominator to subtract

x/(x^2+3x+2) - 1/(x^2+3x+2)

results x-1/(x^2+3x+2)

Answers

Answer:

d) 20

Step-by-step explanation:

To find possible side lengths use the triangle inequality theorem. The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So for the measurements 6, 11, 20 to make a triangle 6+11 must equal at least 20, which isn't true. Therefore, 20 cannot be a measurement for this triangle.

how far can you run in 5/7 of a hour if you run at a speed of 8 2/5 miles per hour

Answers

Answer:

6 miles

Step-by-step explanation:

At a speed of 8 2/5 miles per hour, you can run a distance of 6 miles

How to find distanceSpeed = 8 2/5 miles per hour

Time taken = 5/7 of a hour

Distance = x

Speed = distance / time taken

8 2/5 = x ÷ 5/7

42/5 = x ÷ 5/7

cross product

42/5 × 5/7 = x

x = (42×5) / (5×7)

= 210/35

= 6 miles

Therefore, you can run a distance of 6 miles at a speed of 8 2/5 miles per hour

Answers

Answer: Choice B)  y = (-2/3)x + 6

===================================================

Work Shown:

2x+3y = 18

3y = 18-2x ..... subtract 2x from both sides

3y = -2x+18

y = (-2x+18)/3 .... divide both sides by 3

y = (-2x)/3 + 18/3

y = (-2/3)x + 6

As a quick shortcut, anything in the form Ax+By = C will convert to y = (-A/B)x+(C/B) when you solve for y.

The slope is -A/B and the y intercept is C/B

If the surface area of a sphere is 144pi square centimeters, what is the length of the radius of the sphere, in centimeters

Answers

Answer:

6cm

Step-by-step explanation:

The formula for the surface area of a sphere = 4πr²

From the Question, we are given:

The surface area of a sphere = 144pi square centimeters = 144π cm²

The length of the radius of the sphere, in centimeters is calculated by:

4πr² = 144π

Divide both sides by 4π

4πr²/4π = 144π/4π

r² = 36

Square root both sides

√r² = √36

r = 6cm

Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.
