Answer:
16 + 3n
Step-by-step explanation:
a = 19 ; common difference = 22 - 19 = 3
a(n) = a + (n -1 ) *d
= 19 + (n-1)*3
= 19 + 3n - 3
= 16 + 3n
Answer:
Step-by-step explanation:
the answer is D. 6 ≤ x < ∞
I'm guessing you'd combine them. And the end equation would be
81x6y
Answer:
c=1.96
Step-by-step explanation:
2.1/c=1.5/1.4
2.1*1.4=1.5*c
2.94/1.5=1.5c/1.5
c=1.96
Answer:
y = 1/2 (2)x
Step-by-step explanation:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3 Solve each equation for a.
2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3
Cross multiply: 2b3 = 4b2 Divide both sides by b2
2b = 4 a = 2/4 = 1/2
b = 2
