Using a scale that has increments that are somewhat large, you could get an error if you reach half of the measuring unit. This is because when you arrive at a measurement greater than half of the measuring unit, you would have to round it up. Therefore, the greatest possible error when measuring to the nearest quarter of an inch is 1/8 inch. The greatest possible error when measuring to the nearest quarter of an inch is how the reader reads the measurement. Sometimes, we base our answers to what we can see and what we see may be different from others.
Some institutions use 360 days a year (because then they charge more interest than 365 days).
Assuming the 360 days a year rule, the the daily rate is
6.5% for a year, or 270/360*6.5% for 270 days.
The future amount is then
4000*(1+0.065*270/360)
=$4195 (simple interest).

What multiplies to -18 but adds to -7?
-9*2=-18
-9+2=-7
Leaving you with...
(y-9)(y+2)
As we can see the grouped factoring is not all negative...
Thus, your answer.
Answer:
32x107=3424=3,424*
Step-by-step explanation:
Answer:
<em><u>x=2, y=4</u></em> (as a point,) (2, 4) (last part is unnecessary unless you are graphing)
Step-by-step explanation:
Use substitution.
Substitute y for 2x.
Since y=2x, you can plug 2x into the place where y goes...
Instead of y=-1/2x+5
2x=-1/2x+5....Now solve
2.5x=5 (Sorry my computer cannot type fractions very clearly)
/2.5 /2.5 (dividing by 2.5 on both sides)
<u><em>x=2</em></u>
Now just plug x into any of the equations to find y (preferably the easier one).
y=2x becomes
y=2*(2)
=4
<em><u>y=4</u></em>
