Answer:
8x-2y = -24
Step-by-step explanation:
Slope = 34
Y-intercept = 7
Answer:
The correct answer is B.
Step-by-step explanation:
In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.
Discriminant = b^2 - 4ac
The only of the equations that does not yield a perfect square is B. The work for it is done below for you.
Discriminant = b^2 - 4ac
Discriminant = 7^2 - 4(2)(-5)
Discriminant = 49 + 40
Discriminant = 89
Since 89 is not a perfect square, we cannot factor this.
Answer:
He can run 20 ft in 15 seconds
Step-by-step explanation:
we need to change yards to ft
3ft = 1yd
100 yds * 3ft/1yd = 300 ft
distance = rate * time
300 ft = rate * 15 seconds
divide by 15 seconds on both sides
300 ft/15 seconds = rate
20 ft/sec
He can run 20 ft in 15 seconds
In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is
. So the 16th term of the sequence is -29.
