Answer:
Step-by-step explanation:
The two different rentals give rise to two equations. Let t and c represent the rental costs of a table and chair, respectively. The rentals are ...
5c +2t = 23
3c +8t = 58
Cramer's rule tells you ...
c = (2·58 -8·23)/(2·3-8·5) = -68/-34 = 2.00
t = (23·3 -58·5)/-34 = -221/-34 = 6.50
The cost to rent each chair is $2.00.
The cost to rent each table is $6.50.
_____
<em>Cramer's Rule</em> says the solution to
ax +by = c
dx +ey = g
is ...
x = (bg -ec)/(bd -ea)
y = (cd -ga)/(bd -ea)
When the equation's coefficients are not convenient to achieve elimination of a variable, Cramer's rule can get to the solution very quickly. The same number of math operations are involved, but they are expressed in terms of a formula that can be used with no guesswork.
AB/DE = BC/EF
CA/FD = AB/DE
MJ/QN = JK/QP
LM/PQ = MJ/OP
Answer:
6x¹⁰ - 96x²
6x²(x⁸ - 16)
B) 6x²(x⁸ - 16)
6x²[(x⁴)² - 4²]
6x²[(x⁴ - 4)(x⁴ + 4)]
6x²(x⁴ + 4)[(x²)² - 2²]
6x²(x⁴ + 4)(x² - 2)(x² + 2)
