Step-by-step explanation:
Y = -3x - 1......so we sub in -3x - 1 in for y in the other equation
2x + 5y = 12
2x + 5(-3x - 1) = 12....now distribute the 5 through the parenthesis
2x - 15x - 5 = 12...add 5 to both sides
2x - 15x = 12 + 5..combine like terms
-13x = 17...divide both sides by -13
x = -17/13
now sub in -17/13 for x in the other equation
y = -3x - 1
y = -3(-17/13) - 1
y = 51/13 - 1
y = 51/13 - 13/13
y = 38/13
so the solution is (-17/13, 38/13)
old (first visit): 550 grams
second visit: gained 350 grams
third visit: gained 300 grams
new: cora's kitten is now 1200 grams.
-> now, we must find the percent increase between 550 and 1200.
to find percent increase, we use this equation
new - old / old x 100
-> (1200 - 550 / 550) x 100
(650 / 550) x 100
= 1.18 x 100
<u>percent increase: 118% </u>
