Answer:
y1= 0, y2= 5/3
Step-by-step explanation:
Remove the parentheses and multiply
then cancel the equal terms
collect the lie terms
move the variables to one side
divide both sides by two
split into possible cases
then solve the equation to get
y= 0 and
y= 5/3
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
For a geometric sequence,
1. The sequence is :
3, 13, 23, 33,...
It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625
So, the sequence is geometric as the common ratio is same. It is true.
I guess you want to find the average speed for the whole journey
average speed = distance travelled / time
the distance from home to the shop = speed * time = 0.5*10 = 5 miles
time for travelling back = distance / speed = 5/30 = 1/6 hours
average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
Answer:
-1
Step-by-step explanation:
-9a<u>(-16+3)</u>=4a ; solve for whole numbers first.
-9a-(13)=4a ; A negative 16 plus a positive 3 is 13.
-9a-4a=13 ; Switch 13 and 4a to make it easier to solve.
-13a=13 ; Now divide each side by -13.
a=-1
