Answer:
Non-linear equations:
Step-by-step explanation:
Linear equation: y = mx + b
Therefore, a linear equation has 2 variables that have no exponents.
So the non-linear equations are:
(this is a quadratic equation - polynomial with degree 2)
(this is an exponential equation)
Answer:
$68 and $10.792
Step-by-step explanation:
The computation is shown below:
The total bill received by them is $56.80
The total bill after adding 19% tip is
= Total bill + tip amount
= $56.80 + 19% of $56.80
=$56.80 + $10.792
= $67.592
= $68
The sever would make the amount i.e. equivalent to the tip amount i.e $10.792
Answer:
4x²+12x+9
Step-by-step explanation:
1. 2x times 2x = 4x²
2. 2x times 3 = 12x
3. 3 x 3 = 9 or 3² also equals 9
Answer:
- Iced tea is $4.50 per gallon
- Lemonade is $4.75 per gallon
Step-by-step explanation:
<u>Price</u>:
- Iced tea = x, lemonade = y
<u>Equations</u>:
- 2x + 3y = 23.25
- 5x + 4y = 41.50
<u>Multiply the first equation by 5 and the second equation by 2 and subtract to eliminate x:</u>
- 5(2x + 3y) - 2(5x + 4y) = 5(23.25) - 2(41.50)
- 10x + 15y - 10x - 8y = 33.25
- 7y = 33.25
- y = 33.25/7
- y = 4.75
<u>Use the first equation to find x:</u>
- 2x + 3(4.75) = 23.25
- 2x = 23.25 - 14.25
- 2x = 9
- x = 9/2
- x = 4.50
Iced tea costs $4.50 per gallon
Lemonade costs $4.75 per gallon
The nearest hundred thousand would be 500,000
