For all parts of this question, use the function y + 2 = 3(x + 4)
vekshin1

i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier

y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis

y + 2 = 3x + 12. subtract 2 from both sides

y = 3x +10

now to fill in the chart simply plug in the value of x to see what value of y it produces

y = 3(-2) +10

y = -6+10

y = 4

(-2,4)

y = 3(0) + 10

y = 0 + 10

y = 10

(0,10)

y = 3(2)+10

y = 6 + 10

y = 16

(2,16)

y = 3(4) + 10

y = 12 + 10

y = 22

(4,22)

Q varies inversely as the square of p, and Q = 36 when p = 7. Find Q when p = 6.
snow_lady [41]

Answer:

49

Step-by-step explanation:

1. Calculate the constant of proportionality

Q = k/p²

k = Qp²     Multiplied each side by p²

  = 36 × 7²

  = 36 × 49

  = 1764

2. Calculate the new value of Q

Q = 1764/p²

  = 1764/36

Q = 49
