Answer: 3rd answer choice; A and C
Step 1 is to locate the point (1,2). You start at the origin, then move 1 unit to the right and 2 units up. Alternatively, you can draw a vertical line through 1 on the x axis and a horizontal line through 2 on the y axis. The horizontal and vertical line cross at (1,2)
Step 2 is to then determine which lines go through (1,2). The two lines in question are line A and line C. So the intersection of line A and line C is the point (1,2). This point satisfies the equations that make up these lines. So that is why it is considered a solution to just these two equations only (ignore the other lines).
Answer:
Step-by-step explanation:
Step 1: Convert into improper fractions
Step 2: Find least common denominator and find equivalent fractions
Step 3 : Do the required operation

Least common denominator of 2 , 4 = 4

Answer:
f(-1) = 121
Step-by-step explanation:
f(x) = (5-6x)^2 (First we will substitute x for -1)
f(-1) = (5-6(-1))^2 (Then we will combine like terms)
f(-1) = (11)^2 (Then we will square it)
f(-1) = 121 (You are done)
