Answer:
d=-4 and a=10
Step-by-step explanation:
The sum of a arithmetic sequence is given by (n/2)*(2a+(n-1)d). Comparing coefficients with the given Sn, we have; a-d/2=12 and d/2=-2, d=-4 and a=10.
Answer:6
Step-by-step explanation:
$220 × 6 = $1320 this is how much it cost to pay 6 carpenters for one day. Now lets find how much it cost to 12 plumbers at $260 a day. $260 × 12 = $3120 this is how much it costs to pay 12 plumbers a day.
An irrational number is any number that is a real number, a full number or whole one, and that can`t be shown as a ratio. It is a number that cannot be shown as a simple fraction. An irrational number is one that is shown as a repeated decimal or fraction.
Answer:
g(x) = f(2) at x = 4
Step-by-step explanation:
Assuming that you meant g(x) = 2x - 3:
Set f(2) = g(x) and solve the resulting equation for x:
f(2) = 3(2) - 1 = g(x) = 2x - 3.
Thus, 6 - 1 = 2x - 3.
Adding 3 to both sides and simplifying the result, we get:
8 = 2x, or x = 4.
g(x) = f(2) at x = 4.
