PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) Part B: What is the solution to the pair of equations? (4 points)

Answers

Answer:

Step-by-step explanation:

y = 6x − 4

y = 5x − 3

A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b

x                   y=6x-4                  y=5x-3

1                    y=2                        y=2

2                    y=8                        y=7

0                     -4                            -3

slope  :

y=6x-4    slope is 6            y intercept(0,-4)

y=5x-3      slope is 5          y intercept (0,-3)

solution of the pair of equation is  the point of intersection :

6x-4=5x-3

6x-5x=-3+4

x=1   and y=6x-4   ⇒ y=6-4=2

Step-by-step explanation:

We know,

Substituting the value of cot A in the given equation, we get

The ratio of red marbles to blue marbles is 3:5. If there are 225 blue marbles total in the collection, how many of each color are there? Please show your work.

Answers

Answer:

Red balls =  84     Blue balls =  140

Step-by-step explanation:

Ok so there are 225 marbles

And ratio here is Red : Blue = 3 : 5

So Red marbles = 3x whereas Blue marbles = 5x

Therefore,

3x + 5x = 225

8x = 225

x = 28.125 = 28

Red balls = 28*3 = 84     Blue balls = 28*5 = 140

(Pls check whether total no of balls is 224)

Step-by-step explanation:

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells x x shirts can be found using the function f ( x ) = 8 x − 40. F(x)=8x−40. Find and interpret the given function values and determine an appropriate domain for the function.

Answers

Answer:

Domain = [0, ∞).

Step-by-step explanation:

he profit, in dollars, when the company sells x shirts can be found using the function

[tex]f(x)=8x-40[/tex]

For x=0,

[tex]f(0)=8(0)-40=-40[/tex]

It means, if company sells 0 shirts, then company makes loss (because of negative sign) of $40.

For x=5,

[tex]f(5)=8(5)-40=0[/tex]

It means, if company sells 5 shirts, then company makes profit of $0 means no loss no profit.

For x=10,

[tex]f(10)=8(10)-40=40[/tex]

It means, if company sells 10 shirts, then company makes profit of $40.

Domain is the set of input values.

We know that number of shirts can not be negative, therefore the value of x is always greater than or equal to 0.

Domain = [0, ∞).

Therefore, the domain for the function is [0, ∞).

(6a - 10) = 12 – (6 - 3a), when b=11
A = ?

Answers

Answer:

a = 5.333..  or 5 1/3

Step-by-step explanation:

I am not sure what your question is but it looks like you need to solve for  a.

Based on that fact:

6a - 10 = 12 - 6 +  3a      you multiply -1  by each term in the parenthesis

Then it is simple algebra

6a -10          =        6+ 3a

     +10               + 10                   add 10 to both sides

6a                =  16  + 3a

-3a                         -3a                 add  -3a to both sides

3a  = 16                     Divide both sides by 3

a = 5.3333

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that the value of the segment Qr=58 and pq=13. The value of segment PR will be calculated as below:-

PR = QR + PQ

PR  = 13 + 58

PR = 71

a carpenter has a wooden dowel that is 96 cm long. she wants to cut it into two pieces so that one piece is 5 times as long as the other. what is the length of the longer piece? ​

Answers

Answer:

30 cm

Step-by-step explanation:

In this problem (word problem), we are examined on how to express equations from words.

let us initialize some variables

let the length of the first piece (the short piece) be x

and that of the second(the longer piece) be 5x

given that the total length is 96 cm

Also from the problem statement, the total length can be expressed as

5x+x= 96

6x= 96

divide both sides by 6 to solve for x

x= 96/6

x= 16

now the longer side = 5x

        the longer side= 5*6

       the longer side = 30 cm

find BC.

3x-1

А в

Answers

Answer:

BC = 26

Step-by-step explanation:

Given that:

B is the midpoint of AC

Then AC = AB + BC

AC = 8x - 20 and AB = 3x - 1

Then,

8x - 20 = (3x - 1) + BC

8x - 20 - (3x - 1) = BC

8x - 20 - 3x + 1 = BC

5x - 19 = BC

But AB = BC

5x - 19 = 3x - 1

5x - 3x = - 1 + 19

2x = 18

x = 9

Hence,

Since BC = AB = 3x - 1

3(9) - 1

27 - 1

= 26
