Sophie would’ve earned more
She would’ve earned $37 more
Calculations:
Sophie:
$330(1+4%*2)
=$356
Simple interest: $356-$330
=$26
Avi:
$290(1+5%*2)
=$319
Simply interest: $319-$290
=$29
$29-$26
=$3
We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.
Answer:
5y + 3
Step-by-step explanation:
When multiplying a variable (y) with a number, you combine the two together , so 5y. Since you're adding 3, you leave the 3 alone and write the expression out as 5y + 3.
