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.
Answer:
-11/12 make sure you press the negative
<em>- 8n + 9</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>A - B = ( -3n + 2 ) - (5n - 7)</em>
<em>= - 3n + 2 - 5n + 7</em>
<em>= - 8n + 9</em>
<em>Good luck !</em>
Area of a triangle is base times height divided by 2. I multiplied 5 times 14 and got 70. The divided by 2 and got 35. soooo, 34?
Answer: C) All real values of x such that 
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,
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.
