Answer:

y=3x+3

Step-by-step explanation:

to find the y-int, you need to find the point the is on the y-axis (0,x). Or, 3 in this situation

for slope, you just need to do rise over run, or up and down first then, left and right. If i do that for this equation, I will get 3/1 which is the slope.

The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf​ hold? Write an equation to help solve this problem.

Answers

Answer:

328 books

An equation to solve the problem:

7x = 2296

Step-by-step explanation:

The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf​ hold? Write an equation to help solve this problem.

They said each shelf can hold the same number of books

And we have 7 shelves

Total number of books = 2296

Hence:

The number of books each shelf can hold = 2296 books/7 Shelves

= 328 books

Hence, each shelf can hold 328 books

An equation to solve this problem =

Number of books can be represented by x

Hence:

7x = 2296

Answer:

The marked angle GEF is 25

Step-by-step explanation:

Here, we want to calculate the value of the marked angle

Mathematically, a diagram should do justice to this

Please check the attachment for the diagram

The theorem we want to use is that the sum of opposite interior angles equals the exterior angle

Thus, mathematically;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

6x-3x = 20-2

3x = 18

x = 18/3

x = 6

The angle marked GEF is x + 19

That will be 6 + 19 = 25

Which of the following best approximates the line of best fit?

Answers

Step-by-step explanation:

Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.

The answer is D.

The solution is, The graph that best approximates the line of best fit is option D.

Here, we have,

we know that,

Line of Best Fit:

This refers to the line that is used in a scatter plot to show and indicate a relationship between the points so that the number of points above the line is equal to the points below the point.

Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.

Hence, from the given illustration of graphs, we can see that using the eyeball method, we can see that the number of points in option D is best balanced between the line above and below.

The answer is D.

Answers

Answer:

Step-by-step explanation:

Draw vector u in standard position. To add u to v, shift u three units to the right and one unit up so its initial point coincides with the terminal point of v. Use a dotted line to depict the shifted vector u. Finally, draw the resulting vector with its initial point at the origin and endpoint at v + u. The component form of this resulting vector is <5, -4>.

Work out the equation of the straight line which has a gradient of 2

Answers

Note: It seems you may forget to write the complete statement. Maybe you should have either mentioned the y-intercept or any other point to work out the equation.

Anyways I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.

Answer:

We conclude that the equation of a line using the slope-intercept form is

[tex]y=2x+2[/tex]

Step-by-step explanation:

I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.

The slope-intercept form of the equation

[tex]y=mx+c[/tex]

Here

m is the slopec is the y-intercept

Substituting the point (1, 4) and m=2 to determine the y-intercept

[tex]y=mx+c[/tex]

[tex]4 =2(1)+c[/tex]

[tex]4 = 2+c[/tex]

[tex]c = 4-2[/tex]

[tex]c = 2[/tex]

Thus, the equation of a line using the slope-intercept form is

[tex]y = mx+c[/tex]

m=2c=2

[tex]y=2x+2[/tex]

Therefore, we conclude that the equation of a line using the slope-intercept form is

[tex]y=2x+2[/tex]

Answers

Answer:

Step-by-step explanation:

Two or more expressions with an Equal sign is called as Equation.6(3-5w)=5(4-2w)-20w have no solution

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 6 times of three minus five w equal to five times of four minus two w minus twenty w.

6(3-5w)=5(4-2w)-20w

Apply distributive law on LHS side

6(3)-6(5w)=5(4)-5(2w)-20w

18-30w=20-10w-20w

Let us take all the variable w terms to one side

18-20=30w-10w-20w

-2=0

Hence based on the given equation , it has no solution.
