What is the equation of the line in slope-intercept form?
A.) y = x + 8
B.) y = x - 8
C.) y = 8x + 8
D.) y = 8x - 8

Answer:

56÷2=28

Circumference=2×3.142×r

c= 2×3.142×28=175.952

hundredth =175.95cm

Area=3.142×r^2

A= 3.142×28^2=2463.328

hundredth =2463.33cm^2

Answer:

y=2x-5

Step-by-step explanation:

Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.

Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.

y=2x+b

Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.

Answer:

Step-by-step explanation:

The slope of the line passing through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(3, 4)   ⇒   x₁ = 3,  y₁ = 4

(8, -3)   ⇒     x₂ = 8,  y₂ = -3

So, the slope:

                     [tex]m=\dfrac{-3-4}{8-3}=\dfrac{-7}{5}=-1\dfrac25[/tex]

Answer:

From my research, the coordinate points can be found on image below. Since N is the reflection of B and O is the reflection of C, if we were to draw a line to the right of N and a vertical line below C, the point of intersection of these two lines should give us the location of point O. Doing just that, point O is found at (5,5).

Step-by-step explanation:

Hope I helped You :) have a good day.

The coordinates of point O of the given Reflection is; 5, 5

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Since,  The coordinates point is missing and so I have attached it.

Now, from the question, we are told that N is the reflection of B and O is the reflection of C.

Thus, from the attached image, drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines would give us the location of point O.

Hence, Drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines which is point O has coordinates at (5,5).

Answer:

The correct answers are;

4 * 3 1/4

3 1/4 + 3 1/4 + 3 1/4 + 3 1/4

13/4 + 13/4 + 13/4 + 13/4

Step-by-step explanation:

Given 4 ropes each 3 1/4 feet long

1 rope = 3 1/4 feet long

4 ropes = x

cross multiply

1 * x = 4 * 3 1/4

x = 4 * 3 1/4

Since 3 1/4 is in 4 places, the total length can also be expressed as;

3 1/4 + 3 1/4 + 3 1/4 + 3 1/4

We can also rewrite as an improper fraction

Since 3 1/4 = 13/4

Total length = 13/4 + 13/4 + 13/4 + 13/4

They are not equal they are not complementary angles or any other equality.

Answer: 2572.44

V=(4/3)πr^3 (the formula for volume of sphere)

plug in 17/2 for r  (17 is the diamater and r is the radius which is half of the diamater)

Put this in calc

(4/3)π17/2^3

You get 2572.44

Answer:

120 cm, 160 cm, 80 cm, 360 cm

Step-by-step explanation:

The ratio 3:4:2:9 is the same as the ratio 3x:4x:2x:9x

We add all the terms of the second ratio:

3x + 4x + 2x + 9x = 18x

18x = 720

x = 40

3x = 3(40) = 120

4x = 4(40) = 160

2x = 2(40) = 80

9x = 9(40) = 360

Answer: 120 cm, 160 cm, 80 cm, 360 cm

Answer:

They all look right but i'm not sure about the last one?

Step-by-step explanation:

Answer:

A) False

B) True

C) True

D) False Solution is actually (-3, -3)

work below

Note: Used Elimination Method

Multiply the first equation by -2,and multiply the second equation by 1.

−2(−2x+y=3)

1(3x+2y=−15)

Becomes:

4x−2y=−6

3x+2y=−15

Add these equations to eliminate y:

7x=−21

Then we solve 7x = −21 for x:

7x = −21

7         7

(we Divide both sides by 7)

x=−3

Now that we've found x let's put it back in to solve for y.

Put down an original equation:

−2x+y=3

Substitute−3 for x in−2x+y=3:

(−2)(−3)+y=3

y+6=3(Simplify both sides of the equation)

y+6+−6=3+−6(Add -6 to both sides)

y= −3

Solution

(-3, -3)

Answer:

Sketch of a cube with side = 4 in as shown.

The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.

The area of the cross section is

4*4 = 16 in²

The perimeter of the cross section is

4+4+4+4 = 16 in.

Answer:

Step-by-step explanation:

You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.

6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23.  Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.

Step-by-step explanation:

2 1/5 is equivalent to 0.022.  Yes, 0.0215 is less than 0.022.

This is clearer if you write the two values in a column:

0.0220  (larger than 0.0215)

0.0215   (smaller than 0.0220)

Answer:

d=8
