What is the slope of the line on the graph?



Enter your answer in the box.

Answers

To find the slope,we can use the slope formula:
(y1 - y2)/(x1 - x2)
Where x and y are y coordinates and x coordinates respectively.

To find the answer, put any two points into the formula.

In this case, (1,5) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,5), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

(5 - ( - 1))/( 1- 0) \n = (5 + 1)/(1) \n = ( 6)/(1) \n = 6
Therefore the answer is 6.

Find the surfacs area of a cone wirh a slant height of 18in and a radius of 7in

Answers

Formula of the surface area of a cone is:
S.A = Area of base + (1)/(2) × Perimeter of base × height of prism

S.A = \pir² + \pirl
       = \pi(7)² + \pi(7)(18)
       = 49\pi + 126\pi
       = 175\pi in² (in terms of \pi)
       = 549.7787 in²
       ≈ 550 in²

Which steps should be used to graph the equation y – 4 = y minus 4 equals StartFraction one-third EndFraction left-parenthesis x plus 2 right-parenthesis.(x + 2)?

Answers

Answer:

Step-by-step explanation:

You have to graph the following equation:

y – 4 = (x + 2)

Lets start by summing 4 in both sides:

y – 4 + 4= (x + 2) + 4

y = (x + 2) + 4

By commutative property we can write that:

y = x + (2 + 4)

y = x + 6

So, our equation can be written as y = x + 6

Now, for drawing the graph we need two points (x1, y1) and (x2, y2)

As the independent term is 6 we know the function passes trough (0, 6). Now we need another point, lets try with some simple. Lets see what happens is x is equal to 1:

y = 1 + 6 = 7

So, the function passes trough (0, 6) and (1, 7). For graphing it we just ned to identify those points in the axis and draw a line that crosses both of them. Here I attach a graph for this.

Answer:

The answer is C. Hope this helps you!

Step-by-step explanation:

1. Plot the point (–2,4).

2. From that point, count left 3 units and down 1 unit and plot a second point.

3. Draw a line through the two points.

What is the difference between 3/5 and 2/10

Answers

The answer is 2/5. This is because if you simplify 2/10 it becomes 1/5. Then, you do 3/5 subtracted by 1/5 and that is how you get to 2/5.

An inventor sells her product for 376 Chinese yuan. This price has the same value as 55 U.S. dollars. Based on these numbers, what is the conversion rate between Chinese yuan and U.S. dollars? Choose the closest answer.376 U.S. dollars = 1 Chinese yuan
1 U.S. dollar = 0.15 Chinese yuan
6.84 U.S. dollars = 1 Chinese yuan
1 U.S. dollar = 6.84 Chinese yuan

Answers

Answer:

1 U.S. dollar = 6.84 Chinese Yuan

Explanation:

Take the number of Yuans and divide it by the number of U.S dollars.

376 / 55 = 6.836363636363 \n

then round to 6.84
