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
Answer:
y = 3x - 6
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (2, 0) ← 2 points on the line
m = 
= 
= 
= 3
the line crosses the y- axis at (0, - 6 ) ⇒ c = - 6
y = 3x - 6 ← equation of line L
To find 5/6 of 12, you do 5/6 multiplied by 12
12*5/6 (first multiply 12 by 5 and leave the answer over 6)
60/6 (simplify)
The final answer is 10
Hope this helps!
2/3÷4/5
2/3*5/4
10/12
5/6
Hope this helps :)
40% Because if the shoe is $80 and went on sail to $50 they would have to raise the original price by 20% there for when they say it’s on sail for 30% off it’s really should just be 20% off
