Answer:
y = 0.5x +10
Step-by-step explanation:
If x represents the number of days since Rosie planted her tomato plant, then 0.5x is the number of centimeters it has grown. This growth is added to its initial height (10) to get the number of centimeters high the plant is after x days:
y = 0.5x +10
Answer:
Step-by-step explanation:
y = ab^x where 0<b<1 for exponential decay
an example would be y = 3(1/7)^x
2x-10=44+8x
Subtract 2x from both sides
-10=44+6x
Subtract 44 from both sides
-54=6x
Divide 6 on both sides
Final Answer: x= -9
Answer:
40 units
Step-by-step explanation:
Given:
Perimeter of ∆ABC = 85 units
AC = 4z
AB = 3z + 3
BC = z + 2
Required:
Numerical value of AC
SOLUTION:
Perimeter of ∆ = sum of all its sides
Perimeter of ∆ABC = AC + AB + BC
85 = 4z + (3z + 3) + (z + 2)
Use this equation to find the value of the variable, z
Collect like terms
Subtract 5 from both sides
Divide both sides by 8
AC = 4z
Plug in the value of x
AC = 4(10)
AC = 40 units
Answer:
$73 for each case
Step-by-step explanation:
Total spent: $584
Numer bought: 8 cases
Divide the total amount of amount on how many cases were spent to get how much each one cost individually
584/8 = 73
