Answer: anser is the last one y-2=1/2(x-(7))
Step-by-step explanation:
-5x⁽²⁺³ˣ) - 2x(x-4)
Let's seperate the equation, and do the first half first.
-5x ⁽²⁺³ˣ⁾
Multiply -5x with 2.
Then, multiply 3x with -5x.
That gives us: -10x - 15x²
Now, let's do the second half.
2x(x-4)
2x²-8x
Now, let's put them together.
(-10x-15x²) - (2x²-8x)
Add like terms.
(-2x² - 15x²) - (-8x - 10x)
Simplify.
-17x² - (-18x)
-17x² + 18x
