Please help me with Part A and B!

Mathematics
1 answer:
Illusion [34]2 years ago
5 0

Answer:

A. When Katina has $280 in her bank account, 4 months have passed. Plug 4 months into Malorie's bank account equation:

a = 50(4) + 100

a = 200 + 100

a = $300

B. Malorie's bank account changes at a greater rate. Katina's bank account amount increases by $20 each month, whereas Malorie's bank account increases by $50.

Ex: month 5

Katina has 300, 20 more than the previous month.

Malorie has 350, 50 more than the previous month

Find the distance between the two points rounding to the nearest tenth (if necessary). (-7, -5)(-3, 4)
aleksklad [387]

Answer:

9.8 ( to the nearest tenth )

Step-by-step explanation:

calculate the distance using the distance formula

d = √( x₂ - x₁ )² + ( y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, - 5) and (x₂, y₂ ) = (- 3, 4)

d = \sqrt{(-3+7)^2+(4+5)^2} = \sqrt{16+81} = \sqrt{97} = 9.8
