Answer:
A squared+B squared=Csquared
Step-by-step explanation:
Use Pythagorean theorem.
x + 2y = 4
2x - 2y = 5
Adding both the equations:
x + 2y + 2x - 2y = 9
3x = 9
x = 3
y = 4-x /2 = 1/2
Answer:
Step-by-step explanation:
Given is a graph of a parabola.
We have to find the equation of the paabola.
We observe from the graph the following points.
i) Vertex is (0,0)
ii) Open downward
iii) Axis of symmetry is y axis or x=0
iv) It passes through (1,4)
The parabola will be of the form
Substitute x=1 and y =4, to find a
1 = -4a(4)
a =
Hence equation would be

Kindly check explanation
Step-by-step explanation:
SMALL SIZE :
AMOUNT OF LIQUID = 250 milliliters
Sales price = $4.50
Cost per milliliter :
Sales price / amount of liquid
$4.50 / 250 = $0.018
MEDIUM SIZE :
AMOUNT OF LIQUID = 500 milliliters
Sales price = $9.95
Cost per milliliter :
Sales price / amount of liquid
$9.95 / 500 = $0.0199
= $0.020 ( 3 decimal places)
LARGE SIZE :
AMOUNT OF LIQUID = 1 LITRE = 1000 milliliters
Sales price = $16.95
Cost per milliliter :
Sales price / amount of liquid
$16.95 / 500 = $0.0199
= $0.01695
= $0.017 ( 3 decimal places)
A) LARGE < SMALL < MEDIUM
B) LEAST EXPENSIVE WAY TO BUY 1500 milliliters of green cleaner :
1 large size + 2 small sizes
$16.95 + 2($4.50)
$16.95 + $9.00
= $25.95
C.) MOST EXPENSIVE WAY TO BUY 1500 milliliters of green cleaner :
3 medium sizes
3 * ($9.95)
$29.85
