Answer:
28.84
Step-by-step explanation:
Simplify the inside of root first
147 / 3 = 49
49 + 3 = 52
4 (root) 52 = 28.8444102
Step-by-step explanation:
First, let's rewrite the equations.
1/2x + 1/3y =6
x - y = 2
The easiest system to use for substitution is the second one. Let's solve for X.
x - y = 2
add y to both sides!
x = 2 + y
Now that we know x = 2 + y we can use it to substitute in the first equation.
1/2(2 + y) +1/3y = 6
1 + 1/2y +1/3y = 6
5/6y = 5
y = 36/5
Answer: (A)
Explanation: For there to be a solution at any one point, both inequalities must share a common point. This point will then satisfy both inequations, becoming a solution to both inequality.
Let's pick (A).
For there to be at least one solution, the first inequality must have a solution of
. Since the left side has clearly no points common to both graphs. Hence, no solution can exist that will satisfy both.
All of the other graphs have at least one point in common.
(B) has
(C) has
(D) has
Answer: -7, -0.75, -5, 0.5, 0.75, 9, 13
Step-by-step explanation:
Because negative numbers are always less
Answer:
J The relation represents y as a function of x, because each value of x is associated with a single value of y.
