Answer:
I'm not sure. but igs there similar because they both have 2 corresponding angles
Answer:
f(x) = (3x - 7)/5
f^-1(x) = (5y + 7)/3
The DOMAIN is the set of all possible numbers that you can put in for the independent variable and get an answer. If you had g(x) = 1/x, you could NOT put in 0 for x and get an answer because 1/0 is undefined. So the domain is all numbers but 0.
The RANGE is the set of numbers you will get for the dependent variable. If you had g(x) = 1/x, you could NOT get 0 for g(x), no matter what you put in for x. So the range is all numbers but 0.
In both your functions the domain and the range equal all possible numbers. Or all real numbers.
Step-by-step explanation:
Another way to write the answers is:
D = {x | x = R} and R = {f(x) | f(x) = R} where
D = domain, R = range, { } means set, | is such that.
Answer:
1. 37, 2. 1 2/5
Step-by-step explanation:
For Question 1:
Step 1: Replace the x values
x= 3, y=5
Now you get...
9x + 2y ---> (9 x 3) + (2 x 5)
(Remember, if an x value is beside a number, and it is replaced, that replaced number is to be multiplied with the number the previous x value was.)
Parentheses first, Multiplication second, Addition third (look at PEMDAS below :) )
Step 2: Multiply and Add
(9 x 3) + (2 x 5)
27 + 10
37
For Question 2:
Step 1: Replace the x and y values
m = 1, p = 5
Now your equation should look like this:
m + p ÷ 5 ---> 1 + 2 ÷ 5
Now, which one to do first? Use the PEMDAS strategy
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
You have to do it from top to bottom
Division comes first, which means, you have to divide first, then add:
2 ÷ 5 = 2/5
2/5 + 1 = 1 2/5
Hope this helps :)

Answer:
The answer is X=13
Step-by-step explanation:
Answer:
The answer would be 18
Step-by-step explanation:
the formula for area of a triangle is 1/2b*h
so would mulitply 3*3 and get 9/2 which would be 4.5 do that on the otherside and you would get 4.5 again add together and you would get 9
for the square you would calculate the area by multplying b*h to get 9 so 9+9=18
