Divide each term by 10 to get b alone
10b = −10 = 10b/10 = -10/10
b = -1
Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
(3^2)/3 = 3
Cube root of 9 ≈ 2.08
Square root of 9 = 3
Cube root of 27 = 3
Square root of 27 ≈ 5.2
1. 2.0 x 10^-2
2. 2.2 x10^6
3. 2.0 x 10^4
Just covert each until you reach the end, like you know that there are 356 days in a year and 100 years in a century.
PS They're in scientific notation
Answer:
They sold the least lemonade with the recipe that used 7 lemons.
Step-by-step explanation:
A function shows the relationship between a dependent variable and an independent variable. A dependent variable changes as other variables change while an independent variable.
From the function given, the dependent variable is the cups sold which i dependent on the lemons used (independent variable).
From the points, when the lemons used was 3 the cups sold was 37, when the lemons used was 4 the cups sold was 32, when the lemons used was 5 the cups sold was 40, when the lemons used was 6 the cups sold was 35 and when the lemons used was 7 the cups sold was 26.
Hence, They sold the least lemonade with the recipe that used 7 lemons. and They sold the most lemonade with the recipe that used 5 lemons.
