Answer:
-22
Step-by-step explanation:
-3•f(-8)+7•g(2)=
The value of f(x) at x=-8 is
f(-8) = -2
The value of g(x) at x=2 is
g(2) = -4
Substituting these values into the equations
-3 * -2 +7*-4
6 -28
-22

Answer:
Step-by-step explanation:
First, find how many have an Atlantic or Pacific coastline:
14 + 5
= 19
Then, subtract this from 50:
50 - 19
= 31
This means 31 out of the 50 states have neither coastlines:
This is as a fraction
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)
I = PRT/100 where P = pricipal, R = rate and T = number of years. I = interest.
So answer is (3250 * 1.7 * 3) / 100 = $165.75
