The answer should be y = 5x^2+4x-1
This situation shows that <em>the sides lengths of rectangle P is three times longer than the similar sides on Q</em>. <em>x correlates to 4 ft</em>, and <em>9 ft correlates to y</em>.
This means <em>x = 3*4</em> and <em>9 = 3*y</em>.
x = 12 (simplification)
y = 9/3 (division)
y = 3 (simplification)
Answer:
x=4
y=3
Step-by-step explanation:
we have the following equations
3x+y=15 equation 1
5x-4y=8 equation 2
using equation 1 we have:
y=15-3x equation 3
using equation 3 in equation 2 we have:
5x-4(15-3x)=8
5x-4*15+4*3x =8
5x-60+12x = 8
17x=68
x=68/17
so we have x=4
finally in equation 3:
y = 15-3(4)
y = 15-12
y = 3
Answer: $2,393.42
Step-by-step explanation:
I suppose that the salary is yearly.
So in one year, 365 days, the net pay would be $62,400.
Now, "by-weekly" refers to two weeks or 14 days.
If she gets paid $62,400 in 365 days.
Then in 14 she gets paid.
N = (14/365)*$62,400 = $2,393.42
Answer:
