12x² - 3.5y + 10y + 1.5x² + y Combine like terms
13.5x² + 7.5y
Essentially, what you are doing is taking each individual point and moving that point as specified.
So, for example, problem 1 has coordinates as follows: (be aware: I have terrible eyesight, so the points are being named based on what I think the letters are).
X: located at (2,0), move 1 unit left, new location: (1,0)
G: located at (4,0), move 1 unit left, new location: (3,0)
Q: located at (2,-2), move 1 unit left, new location: (1,-2)
C: located at (3,-4), move 1 unit left, new location: (2,-4)
Now, just plot the new shape.
Let me know if you need more help!
Remember that in PEMDAS, you do the parentheses first.
1. For each answer choice, do whatever is in the parentheses first.
2. Multiply that number to the one outside the parentheses
Hint: For this problem, If all the signs in the answer choice are multiplication, they will equal the same number.
CosA=(21^2+23^2-25^2)/2*21*23
cosA=345/966
A=cos^-1(345/966)
A=69.08
