Answer: B
Step-by-step explanation:
The pair are parallel to eachother. The second equation in slope intercept form is y = 3x-3, since they have the same slope they’re parallel.
Answer:
(4, 1)
Step-by-step explanation:
x^2 + y^2 - 2y - 8x - 19 = 0
We rearrange the terms and complete the square twice.
x^2 - 8x + y^2 - 2y = 19
x^2 - 8x + 16 + y^2 - 2y + 1 = 19 + 16 + 1
(x - 4)^2 + (y - 1)^2 = 6^2
The center is (4, 1)
Its not the best drawing but it should help. Then from there you are going to want to do:
A=b×h
A=6×7
A=42m²
The answer is 90
because increased means times so 30 + 30 = 60 + 30 = 90
