Answer:
x=½
y=5
Step-by-step explanation:
(8x+7y=39)2
16x+14y=78
<u>4</u><u>x</u><u>-</u><u>1</u><u>4</u><u>y</u><u>=</u><u>-</u><u>6</u><u>8</u> add the two equations
20x=10.
divide both sides by 20
x=½
8x+7y=39
4+7y=39
7y=39-4
7y=35
y=5
Answer:
$2756.01 to the nearest cent.
Step-by-step explanation:
A = P(1 + r)^t where A is the amount after t years, P = amount invested, r = rate as a decimal fraction.
So here, we have:
A = 1500(1 + 0.052)^12
= 1500 * 1.837337
= $2756.01

Answer:
4z4−6z3−2z2−20z+1
Step-by-step explanation:
4z5−14z4+10z3−16z2+41z−2
z−2
=
4z5−14z4+10z3−16z2+41z−2
z−2
=
(z−2)(4z4−6z3−2z2−20z+1)
z−2
=4z4−6z3−2z2−20z+1
