Answer:
y=-4x+9
Step-by-step explanation:
a line parallel to another line means the two lines have the same slope
so you can already cross out the second and last equation
the y-intercept is 9 so it is positive, not a negative 9
Answer:
B
Step-by-step explanation:
First, check to see which graph has a line going through the point (2,3). B and D are the only ones that have lines going through (2,3) (A comes close but it is not quite).
Next, you need to see which line would be parallel to the equation 3x-y=2. When two lines are parallel, they have the same slope. You have to turn that equation into point-slope formula (y=mx+b with m being the slope and b being the y-intercept). First, subtract 3x from both sides. You will then get -y=-3x+2. Then y needs to be alone (right now it has a -1 attached). Divide both sides by -1 to get y=3x-2. The number in front of the x is the slope, in this case, 3 or 3/1 (we do not care about the y-intercept, it will not help us in this problem since we are looking for a line parallel to this equation and so our line will not have the same y-intercept as this other equation). Since the line in parallel to that equation, we know that this line also has a slope of 3/1. Find the line between B and D that has a slope of 3/1, you get B (the line goes up 3 over 1).
2,6,15,31,......
6-2=4=2X2
15-6=9=3X3
31-15=16=4X4
So the next number should be 31+5X5=56
hope this helps :)
Answer:
94.2ft
Step-by-step explanation:
- The formula for finding the circumstance is the diameter times pi.
- We know the radius. To find the diameter, we double the radius, which would be 30. (2x15=30)
- Next, we multiply 30 by pi. (30x3.14). The answer is 94.2.
- Thus, the answer is 94.2ft.
