Determine the slope of the line that contains the points P(-10, 7) and Q(2, 1). *

slope = -1/2

Step-by-step explanation:

points: (-10,7) and (2,1)

slope (m) = (y2 - y1) / (x2 - x1)

m = 1 - 7 / 2 - -10 = -6/12 = -1/2

slope (m) = -1/2

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
