25
Step-by-step explanation:
I believe
-3^2 + -4^2
9+16=25
Answer: x= 6, y= -2
Step-by-step explanation: hope this helps.
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.
9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
Answer:$1304.89
Step-by-step explanation:
P(1 + r/n)^r*t
500 ( 1 + 0.08/52) ∧ 52*12
500 (1.00154)^624
500 ( 2.61)
1304.88523
You can find that out by first putting two equations in slope-intercept form y=mx+b by solving for y.
3y - x = 2
3y = x+2
y = (1/3)x + 2/3
9y = 3x + 6
y = (3/9)x + 6/9
y = (1/3)x + 2/3
They are the same line as you can see in the final step.
Since the two lines are the same line, (they "coincide") they are coincident.
Coincident means there are an infinite number of solutions, and since they are the same line, there are an infinite number of solutions.
