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

(3+q)/2 = 0

Answer:

y=1.2x-6

Step-by-step explanation:

place in the points

0=1.2(5)+b

distrubutive property

0=6+b

subtract 6 on both sides

-6=b

Where does the 1 come from in (1.0325)

NemiM [27]

Answer: *1*.0325

Step-by-step explanation: When you round it to the nearest tenths place the 3 behind the 0 is less than 4 therefore everything behind the 0 gets taken away. The 0 has no value so you could take it away too along with the decimal point and it will turn into just 1.

There is a bag with 50 popsicles inside. 5

Mkey [24]

Answer: $\frac{6}{25}$

In this case, we're asked to pick one of 12 blue popsicles out of a bag of 50 – from this, we can just write that the probability of picking a blue popsicle is 12/50. Simplifying this, we can divide both the numerator and denominator by 2 to get our final answer of $\frac{6}{25}$
