Answer:
p = -4, q = -3
Step-by-step explanation:
y = -2x +4 ... (1) perpendicular bisector of AB, slope = -2
slope of AB = 1/2
Line AB pass (8,3): (y-3) / (x-8) = 1/2
AB equation: y-3 = 1/2(x-8) y = 1/2x - 1 ... (2)
(2)-(1): 5/2 x = 5 x = 2
y = 0 (2,0) intercept of bisector and AB, it is midpoint of A (8,3) and (p,q)
(8+p)/2 = 2
<u>p = -4</u>
(3+q)/2 = 0
<u>q = -3</u>
Answer:
250
Step-by-step explanation:
20% of 250 is 50. 100% of 250 is 250, therefore 20 percent of 250 equals 50.
More simplified explanation: The question is asking if 50 is 20% of a number, what is the number? So we know that 20% is 1/5 of 100%; if we know that 50 is 20% of something, then we would multiply 50 by 5 to get the answer. We would have to multiply 50 by 5 because if 50 is 20% of a number that would mean that 50 is 1/5 of the number we need to find, so to find the number, you to multiply 50 by 5.
Hope this helps!
Pretty sure its -1
The formula is y2-y1/x2-x1
What’s the question referring to here.
Answer:
- Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles
Step-by-step explanation:
<u>Distance per person:</u>
- Jenny - x, Keith - y, Joanna - z
<u>Equation as per given:</u>
- y = x + 3
- z = 2y = 2(x + 3)
- x + y + z = 16
<u>Substitute and solve for x:</u>
- x + (x + 3) + 2(x + 3) = 16
- 2x + 3 + 2x + 6 = 16
- 4x = 7
- x = 7/4 = 1.75
Then
- y = 1.75 + 3 = 4.75
- z = 4.75*2 = 9.5
