What Is The Slope-intercept Equation For The Line Below?

Answers

Answer 1

Answer:

y = 5/4x - 4

Step-by-step explanation:

First, find the slope by doing change in y/change in x

You have the points (4, 1) and (0, -4), so the slope would be:

-4 - 1 / 0 - 4 = -5 / -4 = 5/4

Then, find the y-intercept

It gives you that the y-intercept is (0, -4).

Now put the equation in the form y = mx + b where m is the slope and b is the y-intercept.

You have that m = 5/4 and b = -4, so it would be y = 5/4x - 4.

The total number of triangles is 5

The total number of all shapes is 13

The ratio is triangles to total

The ratio is 5 to 13

Note

This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.

All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.

Step-by-step explanation:

Given

The attached table

Required

Number of times 3 or 4 will occur

First, we complete the table as follows:

[tex]P(1) + P(2) +......+P(6) =1[/tex]

[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]

Collect Like Terms

[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]

[tex]P(3)= 0.12[/tex]

The expected number of times is:

[tex]E(x)= n * P(x)[/tex]

So, we have:

[tex]E(x) = 300 * (0.12 + 0.21)[/tex]

[tex]E(x) = 300 * (0.33)[/tex]

Answer:

width = 126 ft

Step-by-step explanation:

I'm going to assume that I am solving for width.

Area = width x length

84 = 2/3 x width

Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)

84 x 3/2 = width

width = 126 feet

What are Systems of equations?

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

We can solve this system of equations using the elimination method.

To eliminate y, we can add the second equation to the first equation. This gives:

(4x + 2y) + (2x - 2y) = 10 + 8

Simplifying the left side and combining the constants on the right side, we get:

6x = 18

Dividing both sides by 6, we get:

x = 3

Therefore, the value of x in the solution to the system is 3.

28.)x= -35/11
7x+15=12x+5
Step #1 Subtract 12 from both 7x and 12x on the left and on the right. This is because we only want one x, and combining like terms is not an option therefore we must eliminate.
7x+15= 12x+5
-12 -12
-5x+15=5
Step #2 subtract 15 from both sides.
-5x+15=5
-15 -15
-5x=-10
Step #3 Divided both sides by coefficient which in this case is -5. We want x by itself
x=2

Step-by-step explanation:

6 * 2 = 12

12 - 5 = 7

6 and 5 is your answer

Answer: 6; 5

Step-by-step explanation:

Based on the questions, we set up two equations, let the x be the first number, and y be the second number.

x + y = 11

2x - y= 7

x = 11 - y              [Subtract y from both side]

2x - y = 7

2(11 - y) - y = 7    [Plug in 11-y for x, solve for y]

22 - 2y - y = 7  

22 - 3y = 7        

-3y = -15             [Subtract 22 from both side]

  y = 5

 

x + y = 11             [Plug in 5 for y, solve for x]

x + 5 = 11             [Subtract 5 from both side]

     x = 6
