Answer:
Step-by-step explanation:
11) $175(1 - 0.30)(1 + 0.06) = $129.85
12) slope is 2, so basic equation is
y = 2x + b
plug in your desired point
-5 = 2(-4) + b
b = 3
y = 2x + 3
So the trick I was taught to use was PEMDAS which stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the parenthesis first, followed by exponents if there are any. Multiplication and division are equal. So if there's multiplication and division in the problem, you solve the one closest to the left or start of the equation first. The same rules apply for addition and subtraction. They are both equal so you solve the first one first, even if the subtraction is before the addition.
The statements that are true about the domain and range of the functions f(x), g(x), and h(x) include:
- f(x) has a domain of all real numbers.
- g(x) has a domain of all real numbers.
<h3>What is a function?</h3>
It should be noted that a function simply means a relation between a set of inputs to a set of possible outputs.
In this case, f(x) has a domain of all real numbers as well as g(x) which also has a domain of all real numbers.
In conclusion, the correct options are A and D.

Answer:
The answer is 30
Step-by-step explanation:
To get a.b
For a = <wa, za> and b = <wb, zb>, the dot product represents multiplication sign.
We say,
a•b = (wa)(wb) + (za)(zb)
The next step is to substitute the given information into the above equation we generated.
Then we say,
a•b = 5•4 + 2•5
a.b = 20 + 10
a•b = 30
The answer is 30
