Restaurant 1 : y = 7k + 39
restaurant 2 : y = 2k + 44
7k + 39 = 2k + 44
7k - 2k = 44 - 39
5k = 5
k = 5/5
k = 1
y = 2k + 44
y = 2(1) + 44
y = 2 + 44
y = 46
Dinner would cost $ 46 at either restaurant if Lina's lobster weighed 1 kilogram.
It is in the one-hundred-thousands place
so 400,000
5th term = a1r^4 where a1 = first term and r = common ratio
so 1/4 = a1 * (1/2)^4
a1 = 1/4 / (1/2)^4 = 4
so the sequence is 4 , 4*1/2, 4*(1/2)^2...
= 4, 2, 1, 1/2, 1/4 .....
Answer:
A.) −2y + 10
Step-by-step explanation:
−x − 2y = −10
Add 2y to both sides.
-x = 2y - 10
Multiply both sides by -1.
x = -2y + 10
