Answer: Each burger costs $4 and each order of fries costs $2.5 .
Step-by-step explanation:
Let x be the cost of each burger and y be the cost of each orders of fries.
Given : Jim bought 3 burgers and 2 orders of fries for $17.
Abby bought 2 burgers and 4 orders of fries for $18.
Then, the system of linear equation will become :
Divide by 2 on each sides of equation (2), we get
Eliminate equation (3) from (1), we get
Divide by 2 on both sides , we get
x=4
Put value of x in (3), we get
Subtract 3 both sides, we gte
Divide by 2 both sides , we get
y=2.5
Hence, each burger costs $4 and each order of fries costs $2.5 .
Answer:
Step-by-step explanation:
The above question is in the form of an exponential decay. The equation for an exponential decay is given by:
where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).
Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:
Answer:
1.5 + 1.3228756555323i
1.5 - 1.3228756555323i
Step-by-step explanation:
y = ax^2 + bx + c
a = 1, b = -3, c = 4
Using the quadractic formula:
Note: Kindly ignore the A in the above solution ^
Hence, there is no real solution. It has complex roots.
