Answer:
No
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
32x + 55 = 185
32x = 130
x = 4.0625
We use the formula:
x± s <span>t_<span>(1−c)/2 / </span></span>√n = 5
(1 - c)/2 = (1 - 0.95) / 2 = 0.025
Using the t score calculator at this value, at the 95% confidence internval,
t = 0.5080, So
100 - 19(0.5080) / √n = 5
Solving for n
n = 97
a) 97
b) yes
Ab + 3c = 2x
Subtract 3c from both sides.
ab = 2x - 3c
Divide a from both sides.
b = 2x - 3c / a
