Answer:
SAS congruence postulate. sweetheart.
Step-by-step explanation:
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
Y=5x+11 using the point-slope formula and simplifying
The answer is 4,172
First of all i did 490x9=2880
Then i did 2880+1292=4172
4172
Distance between two points, d, is given by

where: (x1, y1) = (8, 2) and (x2, y2) = (3, 8)
