Let S be Sam's age and b be his brother's age
"8 exceeds" tells us that 8 is greater than the quotient
8 > s/b
The answer is A
Answer:
Step-by-step explanation:
Subtracting and adding functions is actually super intuitive. As a super simple example, if you had f(x)=5+x and g(x)=3 then (f-g)(x) = 5+x-3 = 2+x.
So you basically just add or subtract any like terms. So now with your two functions we can hopefully figure it out. let me know if there's anything you don't understand.
f(x) = x^2+2x-6
g(x) = x+5
(f-g)(x) = (x^2+2x-6) - (x+5) When subtracting you have to distribute the minus sign to the second function so -(x+5) becomes -x-5
(f-g)(x) = x^2+2x-6-x-5 So there's 2x-x and -6-5 which are x and -11
x^2+2x-6-x-5 = x^2+2x-x-6-5 = x^2+x-11
So that's the answer.
Step-by-step explanation:
Total answer is 0 for the first, second and third
The following integer values of x satisfy the given inequality,
4, 5, 6, 7, 8
What is an inequality?
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made using inequality.
Solving the Inequality
The given inequality is,
5x + 4 > 19
5x > 19 - 4
5x > 15
x > 15/5
x > 3
So, the required values of x must be greater than 3 in the given interval, [2,8]
Thus, the integer values of x in the the interval [2,8] that satisfy the given inequality are 4, 5, 6, 7 and 8 (∵ Square brackets of an interval denote inclusion of the terminal values).
