Answer:
C
Step-by-step explanation:
Step 1: plot your 2 known points, (-2,3) and (1,0)
Step 2: after that, you should see that your y value should be a - and your x a +. You can eliminate A and B.
Step 3: check to see if C is a correct answer, (4,-3)
C is the answer, hope that helps
Answer:
8 square units
Step-by-step explanation:
First, split this figure into 3 known figures:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 2 unit triangle
Then solve all these areas:
2 x 2 = 4 / 2 = 2
2 x 2 = 4
2 x 2 = 4 / 2 = 2
Then add all these areas:
2 + 4 + 2 = 8
Answer:
18.285 in.²
Step-by-step explanation:
3 in. × 4 in. = 12 in.²
A = πr²
A = 12.57 in.²
12.57 in.² ÷ 2 = 6.285 in.²
6.285 in.² + 12 in.²
18.285 in.²
Problems: Answers:
12 x - 13 - x - 9 = 10x x = 22
-15k - 1 + 12 + 2k k = 11/13
10a - 7b + 11 + 8a - b - 12 b = (9 a)/4 - 1/8
7a^2 + 10a - 3a - 2a^2 a = -7/5
-c + 5d + 7c - 11d + d - 3c d = (3 c)/5
x^2 - 3xy - 5xy - 7y^2 + 4x^2 + 8y^2 y = 4 x - sqrt(11) x
