We are to determine the wages that Percy receives from working in the library and the coffee cart. We are given with the system of linear equation that would be used for the calculation,
3x + 2y = 36
2x + 5y = 50
Where x and y are the wages from the library and coffee cart, respectively.
Solving for the values of the variables will give us the values of:
x = 7.5
y = 7
Therefore, the answer to this item is that Percy earns a greater hourly wage of $7.50 at the library.
Answer:
The factors of x² - 3·x - 18, are;
(x - 6), (x + 3)
Step-by-step explanation:
The given quadratic expression is presented as follows;
x² - 3·x - 18
To factorize the given expression, we look for two numbers, which are the constant terms in the factors, such that the sum of the numbers is -3, while the product of the numbers is -18
By examination, we have the numbers -6, and 3, which gives;
-6 + 3 = -3
-6 × 3 = -18
Therefore, we can write;
x² - 3·x - 18 = (x - 6) × (x + 3)
Which gives;
(x - 6) × (x + 3) = x² + 3·x - 6·x - 18 = x² - 3·x - 18
Therefore, the factors of the expression, x² - 3·x - 18, are (x - 6) and (x + 3)
Answer:
43.96
Step-by-step explanation:
ok so you use the formula: A= 3.14•r•2 next you plug in your values a=3.14•7•2 3.14•7= 28.98•2=43.96
Answer:
g(-3) = 1
Step-by-step explanation:
We use the top piece of the function since x = -3
g(-3) = x+4 and x = -3
g(-3) = -3 +4 = 1
