What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first equation be P

2x - y = 8   be equation (1)

Let the second equation be Q

4x - 2y = 16  be equation (2)

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ ) = 2

Substituting the values in the equation , we get

Divide equation (2) by 2 , we get

2x - y = 8   be equation (1)

Therefore , the value of equation (1) = equation (2)

Hence , there are infinite number of solutions to the equations

What is the smallest whole number that can be multiplied by 300 such that the product is a perfect cube?

Answers

300=2×2×5×5×3

We observe that 2 and 5 are grouped in pairs and the 3 is left unpaired.

If we multiply 300 by the factor 3 then  

300×3=2×2×5×5×3×3

900=2×2×5×5×3×3 which is a perfect square.

∴ Required number is 3

root of 900  =30

The smallest whole number that can be multiplied by 300 so that the product is a perfect cube is 12 (I think)

To find the answer you need to multiply the number outside of the parentheses by each number/variable in the parentheses.
For example, number 9 says 8(-x-6) you would have to "distribute" the 8 out the both the variable and the number.
8 multiplied by -x is -8x because a negative times a positive is a negative and 8 multiplied by -6 is -48. So there for your answer would be -8x-48

You have to make sure to also remember the multiplying rules:
positive times a positive= positive
positive times a negative= negative
negative times a negative= positive

The school did reach the goal because if you add the games, concessions and donations you get $1232 and if you subtract 28 from it you get $1204 and if you subtract 75 from that you get $1129.
yes, they did reach their goal.

Start by adding 650, 530, and 52 because those are all the money made and received (the income). Then there are the expenses that you have to subtract due to the fact that they're losing money. So from adding all the income you get 1232 and then when you subtract your expenses you get 1129 which is a 29 dollar difference. (i hope this helped :D)

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of paint are needed for one door? Consider drawing a model to help you solve the problem.

Answers

Answer:

1 and 1/4 liters of paint are needed for one door

Step-by-step explanation:

You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 and 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.

Hope this helps!

1.25 liters! if 2 liters is for 1 3/5 door, you will divide 2 and 1 3/5 to get 1.25 per door!
