You divide each side of the equation by 'a', and you immediately have
the value of 'x' in terms of 'a and 'b'.
Answer:
Answer is in attached picture
Step-by-step explanation:
There are no real solutions for the value of 'x'. The two solutions are complex. The fully simplifed answers would be:
x = 4 + 5i*sqrt(7)
x = 4 - 5i*sqrt(7)
15 dimes at 15x10=$1.50
12 nickels at 12x5=$0.60
$1.50+0.60=$2.10
So Alexandra has 15 dimes and 12 nickels
The answer for 4. | She rode her bike 5 and a half miles and 6 miles yesterday so the longer ride is yesterday
6 > 5'1/2
(I do not know 5. sorry.)
I hope this helps
Have a great day!
Answer:
-3/2
The problem:
Find so the function is continuous.
Please read my interpretation of the problem above.
Step-by-step explanation:
If we want continuous at , then we want the following things:
(This means the left and right limits at need to equal.)
Of course the limit and need to both be a number.
So we want to basically solve the following equation:
Subtract 12 on both sides:
Divide both sides by 4:
Reduce:
