Y=4+3x <br>2x+1=y<br>What Is The Point Of Intersection?
nlexa [21]
Y = 4+3x
2x+1 = y

Rewrite as two systems of equations.

3x - y = -4
2x - y = -1

Now use the substitution method to find the point of intersection.

You can also graph both equations on the same xy-plane using your graphing calculator to find the desired point.

What is the domain of f?
lana [24]

Answer: C) All real values of x such that x \le 0

In other words, x must be 0 or smaller.

===================================================

Explanation:

The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.

So,

-2x \ge 0 \\\\-2x+2x \ge 0+2x \ \text{ ... add 2x to both sides}\\\\0 \ge 2x\\\\2x \le 0  \ \text{ ... flip both sides, and the inequality sign}\\\\x \le 0/2  \ \text{ ... divide both sides by 2}\\\\x \le 0

As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.

But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.
