Answer:
Camille did it right.
Step-by-step explanation:
4x-2y=8
Charlize: | Camille:
-2y=8+4x | -2y=8-4x
y=-4-2x | y=-4+2x
The right answer:
4x-2y=8
+2y +2y
4x=8+2y
-8 -8
2y=4x-8
2y/2=4x/2-8/2
y=2x-4 or y=-4+2x
So Camille is right, because she got y=-4+2x.
hello
to solve this question, let's try to write out an equation
Given: A(-4,1), B (6, 1), C (-2, -3), D (4, -3), E (5, 4) and the center O (1, 1); use 3.14 for
UNO [17]
Answer:
Step-by-step explanation:
R = 5 cm = 1 - (-4)
D = 10 cm = 2R
CD = 6 cm = 2 - (-4)
A = π(5)² = 25π cm²
Α ≈ 25(3.14) = 78.5 cm²
C = 10π
C ≈ 10(3.14) = 31.4 cm
The answer is square root 61
