Keep in mind that a coordinate is in the form (x, y), so if you plug those values into the equation y=3x+1, you get 1=3(4)+1, simplified to 1=13, which is an untrue statement. However, I'm assuming you mean that the value of y is 4 and x is 1, which would be written as (1, 4). This would be the solution to this equation because 4=3(1)+1 is 4=4 which is a true statement.
Answer: B) Circle
<u>Step-by-step explanation:</u>
First, complete the square:
x² + 2x + <u> 1 </u> + y² - 8y + <u> 16 </u> = 13 + <u> 1 </u> + <u> 16 </u>
↓ ↑ ↓ ↑
(2/2) = (1)² (-8/2) = (-4)²
(x + 1)² + (y - 4)² = 30
The result is a circle whose center is (-1, 4) and radius is √30
Answer:
10 6s rolls
This is because you have a 1/6 chance divided by the 60
Answer: 30
Step-by-step explanation:
Because you can break the pentagonal base into triangles and the formula to find the area of a triangle is 1/2 Bh so 840/14 = 60 divided by 1/2 = 30
7/6-____=2/3
2/3-7/6 =-x
-1/2=-x
The negatives cancel out so the blank = 1/2
