Answer:
The cost of Daffodil bulb is $ 3.5 And
The cost of Tulip bulbs is $ 5
Step-by-step explanation:
Given as :
The total number of tulip bulbs (T) for front yard = 30
The total number of tulip bulbs for back yard = 16
The total number of daffodil bulbs (D) for front yard = 32
The total number of daffodil bulbs for back yard = 40
The amount spend on front yard = $262.00
The amount spend on back yard = $220.00
so, according to question
30 T + 32 D = $ 262
16 T + 40 D = $ 220
Or, 480 T + 512 D = 4192 ...... 1
And 480 T + 1200 D = 6600 ....... 2
Solving eq 1 and 2
Or, ( 480 T + 1200 D ) - ( 480 T + 512 D ) = 6600 - 4192
Or, 688 D = 2408
∴ D = = $ 3.5
Put The value of D in above eq
480 T + 1200 × (3.5) = 6600
Or, 480 T = 6600 - 4200 = 2400
∴ T = = $ 5
Hence The cost of Daffodil bulb is $ 3.5 And
The cost of Tulip bulbs is $ 5 Answer
Answer:
Slope =
Step-by-step explanation:
Let the equation representing the number of gallons left in the gas tank is,
G = mt + b
Where m = slope of the line
b = y-intercept of the line
Slope of the line passing through two points and
is,
'm' =
Slope of the line passing through (8, 5) and (4, 10),
m =
m = -
Equation of line will be,
G =
Since, point (8, 5) lies on this line,
5 =
5 = -10 + b
b = 15
Therefore equation of the function will be,
G =
Here slope of the function represents the gallons of gas is consumed to drive the car for one hour.
