Answer:
x = -3
Step-by-step explanation:
5x + 3 = 4x,
x + 3 = 0,
x = -3
Answer:
8.8
Step-by-step explanation:
Normally, to find the distance between two points, you would use the distance formula, but these two points have the same x-coordinate, meaning they will form a vertical line when connected. To find the length of a vertical line you find the distance between the y-coordinates, in this case -4.7 and 4.1. Finding the distance is the same as finding the absolute value of the difference:
|4.1 -(-4.7)|
|4.1 + 4.7|
|8.8|
8.8
Answer:
a(n) = -20 + 3(n - 1)
Step-by-step explanation:
a(n) = -20 + 3(n - 1)
Answer:
5859375
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= 
where r is the common ratio and the first term
here r = 
= 
= 
= 5 and = 3, hence
= 3 × 
= 5859375
intercepts the parabola twice: the system
is solved by
intercepts the parabola only once: the system is
which yields
which is a repeated solution
intercepts the parabola only once: the system is
which yields
which is impossible, because a squared number can't be negative.
