Answer:
X Company charges
more than Company Y
Step-by-step explanation:
Given:
Cost of X company = ![\$ 0.35+(\$0.05\times 1 \ minute)](https://tex.z-dn.net/?f=%5C%24%200.35%2B%28%5C%240.05%5Ctimes%201%20%5C%20minute%29)
Cost of Y Company =![\$ 0.15+(\$0.04\times 1 \ minute)](https://tex.z-dn.net/?f=%5C%24%200.15%2B%28%5C%240.04%5Ctimes%201%20%5C%20minute%29)
for n minutes
Cost of X company for n minutes = ![\$ 0.35+(\$0.05\times n \ minute)](https://tex.z-dn.net/?f=%5C%24%200.35%2B%28%5C%240.05%5Ctimes%20n%20%5C%20minute%29)
Cost of Y Company for n minutes =![\$ 0.15+(\$0.04\times n \ minute)](https://tex.z-dn.net/?f=%5C%24%200.15%2B%28%5C%240.04%5Ctimes%20n%20%5C%20minute%29)
Difference for n minutes we get by Subtracting Cost of Y Company for n minutes by Cost of X company for n minutes
Difference for n minutes =
=![(0.2+0.01n)\times 10^2 \ cents](https://tex.z-dn.net/?f=%280.2%2B0.01n%29%5Ctimes%2010%5E2%20%5C%20cents)
X Company charges
more than Company Y
Answer:
x=-2,2
Step-by-step explanation:
Since this is a quadratic equation, -2 or 2 could be the possible answer
Steps
$3x^2=12$
$\mathrm{Divide\:both\:sides\:by\:}3$
$\frac{3x^2}{3}=\frac{12}{3}$
$\mathrm{Simplify}$
$x^2=4$
$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$
$x=\sqrt{4},\:x=-\sqrt{4}$
Show Steps
$\sqrt{4}=2$
Show Steps
$-\sqrt{4}=-2$
$x=2,\:x=-2$
Answer:
= 5n - 1
Step-by-step explanation:
There is a common difference between consecutive terms , that is
9 - 4 = 14 - 9 = 19 - 14 = 5
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 5 , then
= 4 + 5(n - 1) = 4 + 5n - 5 = 5n - 1
