find the equation of the line with a slope of -2 that passes through the point (4,-3)​

Answer:

first problem) he messed up at 4(1 + 5n), only multiplying the 1 by 4, instead of both the 1 and 5n,

work-

-8n + 4(1 + 5n) = -6n - 14

-8n + 4 + 20n = -6n -14

12n + 4 = -6n - 14

18n +4 = -14

18n = -18

n= -1

second problem)  he messed up towards the end, where he put 3x = 3x, then x=0. in this case, x would equal x, so the answer is "infinitely many solutions"

all the other work is correct in that problem

third problem) on the right side of the equation, ( 4x+10+3x-6), when they were adding the like numbers, instead of subtracting 6 from 10, they added 6, giving them 16 instead of 4

correct work-

2x - 8 + 3x +2 = 4x +10 + 3x -6

5x - 6 = 7x + 4

-5x         -5x

-6 = 2x +4

-4           -4

-10 = 2x

-5 = x

hope i helped  :)

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

Subtract the sides of the equation minus 2

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

So ;

[tex]\boxed { x = \frac{3}{5}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]7x + 6 = 17x[/tex]

-Take [tex]17x[/tex] and subtract it from [tex]7x[/tex]:

[tex]7x + 6 - 17x = 17x - 17x[/tex]

[tex]-10x + 6 = 0[/tex]

-Subtract [tex]6[/tex] to both sides:

[tex]-10x + 6 - 6 = 0 - 6[/tex]

[tex]-10x = -6[/tex]

-Divide both sides by [tex]-10[/tex]:

[tex]\frac{-10x}{-10} = \frac{-6}{-10}[/tex]

[tex]\boxed { x = \frac{3}{5}}[/tex]

So, the value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1

Answer:

Section A = 2,200 seats

Section B = 800 seats

Section C = 300 seats

Step-by-step explanation:

Three sections

Section A cost = $60

Section B cost = $70

Section C cost = $120

Total seat = 3300

Total earnings = $224,000

He wants to have twice as many $60 tickets as the sum of the other​ tickets

A = 2(B + C)

A + B + C = 3,300

60A + 70B + 120C = 224,000

substitute A = 2(B + C)

2(B + C) + B + C = 3,300

60(2B + 2C) + 70B + 120C = 224,000

2B + 2C + B + C = 3,300

120B + 120C + 70B + 120C = 224,000

3B + 3C = 3,300 (1)

190B + 240C = 224,000 (2)

Multiply (1) by 80

240B + 240C = 264,000 (3)

190B + 240C = 224,000 (2)

Subtract the equations

240B - 190B = 264,000 - 224,000

50B = 40,000

B = 40,000 / 50

= 800

B = 800

Substitute the value of B into (1)

3B + 3C = 3,300 (1)

3(800) + 3C = 3,300

2,400 + 3C = 3,300

3C = 3,300 - 2,400

3C = 900

C = 900 / 3

= 300

C = 300

Substitute values of B and C into

A + B + C = 3,300

A + 800 + 300 = 3,300

A + 1,100 = 3,300

A = 3,300 - 1,100

= 2,200

A = 2,200

Section A = 2,200 seats

Section B = 800 seats

Section C = 300 seats

Answer:

x=20/3 y=17/3

Step-by-step explanation:

1. x-y=1

2. 2x+y=19

The first equation can be rewritten as 2x-2y=2

We can then subtract the second equation from this:

2x-2y=2

2x+y=19

-3y=-17

y=17/3

Plug this into to solve for x:

x-17/3=1

x=17/3+1

x=20/3

Answer:5 1/3

Step-by-step explanation:

Answer: y=-1/4x+3

Step-by-step explanation:

==================================================

Explanation:

y = mx+b is the general form of slope intercept equations

m is the slope, b is the y intercept

The y intercept is where the graph crosses the y axis. In this case it is at (0,3) so b = 3 is the y intercept

--------------------

The slope can be found through using the slope formula

m = (y2-y1)/(x2-x1)

m = (2-3)/(4-0)

m = -1/4

Or you could note that to go from (0,3) to (4,2) we must go down 1 and over to the right 4.

slope = -1/4 = rise/run

rise = -1 means we go down 1

run = 4 means we move to the right 4

--------------------

Since m = -1/4 and b = 3, we go from y = mx+b to y = (-1/4)x+3

Answer: you have: C(X)=3x+2.00

x=number of minutes

Pay attention to the y=mx+b form where m=slope-->>

3x is the slope...

so it's 3(times the number of minutes) <<---or (x)

This means that the slope is 3, or the fancy way of saying it-->>"rate of change."

The rate of change of the cost of the taxi ride is $3.00 per minute.

A flowchart proof is a visual representation of logical steps used to prove a mathematical statement or theorem.

It involves breaking down the proof into a series of connected statements and reasons, organized in a flowchart format.

Each statement is supported by a reason or justification, demonstrating the logical progression of the proof. Flowchart proofs provide a clear and structured way to present mathematical arguments, allowing for easy comprehension and verification of the proof's validity.

They help in identifying key steps, dependencies, and the overall structure of the proof, making it easier to follow and understand the reasoning behind mathematical statements.
