The answer is
<span>4x12 – 5x6 – 14 = 0
this equation is equivalent to </span>4(x^6)² – 5(x^6) – 14 = 0
so if u=x^6
we have 4(u)² – 5(u) – 14 = 0, and it is a quadratic equation
so the answer is <span>u = x6 </span>
Answer:
Third quadrant
Step-by-step explanation:
Look at the attached image. All the points are in the third quadrant.
Answer:
5%
Step-by-step explanation:
Solving our equation
r = 4537.5 / ( 9075 × 10 ) = 0.05
r = 0.05
converting r decimal to a percentage
R = 0.05 * 100 = 5%/year
The interest rate required to
accumulate simple interest of $ 4,537.50
from a principal of $ 9,075.00
over 10 years is 5% per year.
3x-12y = 5
-x+3y = 9
First step is to make the coefficient of either x or y same.
3x-12y = 5
(-x+3y = 9)3
3x-12y = 5
-3x+9y = 27
-4y = 32
y = -8
Answer:
To most closely estimate the difference, I would round 62,980 to the nearest thousand, so it will be 63,000. That is because when rounding, 63,000 is large enough so that adding will be easy, and 62,980 is relatively close to 63,000.
I would round 49,625 to the nearest thousand, since it would make the subtraction easier and 49,625 is only 375 units away from 50,000.
63,000 - 50,000 = about 13,000.
Hope this helps!
