Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
-1 1/2 is the answer. I'm making 20 characters.
Answer:
Step-by-step explanation:
x+(x+1)+(x+2)+(x+3)=-210
x+1x+1+1x+2+1x+3=-210
4x+6=-210
4x=-210-6
4x/4x=-216/4
x=54
Answer:
The median of the data is 46.
Step-by-step explanation:
Put the numbers in order so it would look like this.
24, 27, 29, 38, 54, 61, 68, 74
The ones in the middle would be the mean, however, there are two numbers in an even-number data, 38 and 54.
Add these two numbers together to get 92 and divide that number by 2 to get your median which is 46.
Answer:
8.75+7.45=16.2. 16.2 is equal to $16.20 so 48.00-16.20=31.8. Jonathan had $31.80 left.
