Answer:

In order down the left side, ...

y = 1/3x +2
y = 1/2x +3
y = 2x +6
y = -2x +3

Step-by-step explanation:

To put a linear equation in slope-intercept form, you solve for y, then simplify.

x -3y = -6

Subtract x and divide by -3:

y = 1/3x +2

2y -6 = x

Add 6 and divide by 2:

y = 1/2x +3

-x +(1/2)y = 3

Add x and multiply by 2:

y = 2x +6

2x +y = 3

Subtract 2x:

y = -2x +3

Comment on the algebra

Note that when we say add, subtract, multiply, or divide by something or other, we mean to do that to both sides of the equation. That is required by the properties of equality.

If you remember the rule: do the same thing to both sides of the equation, then algebra suddenly becomes much easier.

Help please I need it

Answer: -35.375 or -283/8

Step-by-step explanation:

Begin with the parenthese: (-1.5+9.5)=8 and (7+11)

Then you have 5/8+0.4(18)/-0.2.

Multiply 0.4 times that 18 and you get 7.2.

Then you have 5/8+7.2/-0.2

Simplify 7.2/-0.2 which equals -36

Then you have 5/8+-36

5/8+-36=-35.375 or in fraction form -283/8

A café or for senior citizens a 15% discount off it's regular price of $8.95 for the dinner buffet. What percent of the regular

denis23 [38]

Answer:

Price for Senior Citizen = $7.61

Percent of the regular price = 85% off original

Step-by-step explanation:

Regular Price is $8.95

Seniors get 15% off of that. So, first we need to find 15% of 8.95 and then subtract it from 8.95.

To get percentage of a number, we first convert the percentage to decimal (by dividing by 100) and then multiply it with the number.

15% = 15/100 = 0.15

Fifteen Percent of 8.95 is:

0.15 * 8.95 = $1.3425

Senior Citizen Price = 8.95 - 1.3425 = $7.6075

Rounded to nearest cent = $7.61

How much is this as a percentage of original?

Simple, it is 15% off of the regular price, so this price is 100 - 15 = 85% of original price

Money must serve as ___

Molodets [167]

Money must serve as a medium of exchange, a storehouse of value and a unit of account

Answer: Option B, D, and E

Step-by-step explanation:

Money, the term coined in terms of the following three services.

Medium of exchange played as important role to facilitate transactions. Think scenario like without money, then all operations would be exchanged as one product or service exchange for another (barter system).
To be in above, money must retain its value over time i.e store of value. Failure to save money for some time and still remain valuable in return would not resolve the double overlap of desires and therefore would not be accepted as a medium of exchange.
Money also acts as a units of account and is a regular measure of the cost of goods and service exchanged. Knowing the value of a good or the price in cash, both the supplier and buyer can decide how much to deliver and how much to buy.
