Hey there!
2^4=2x2x2x2
2*2=4
4*2=8
8*2=65
It equals 64.
Hope this helps! Let me know if you have any questions:)
Answer = -3/2
Explanation:
Slope = rise/run
Rise = vertical
Run= horizontal
The slope is negative because it goes from right to left.
2x+3(x+1.5)=12 because y=y so you SUBSTITUTE y in for y
Answer: The expression is undefined for x=4 and x=5.
The expression is undefined for any x that makes the denominator 0. This leads to solving a quadratic equation:
![\frac{x+3}{x^2-9x+20}\\x^2-9x+20\neq 0\\x_{1,2}\neq\frac{9\pm\sqrt{9^2-80}}{2}=\frac{9\pm1}{2}\\x_1\neq4\\x_2\neq5](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B3%7D%7Bx%5E2-9x%2B20%7D%5C%5Cx%5E2-9x%2B20%5Cneq%200%5C%5Cx_%7B1%2C2%7D%5Cneq%5Cfrac%7B9%5Cpm%5Csqrt%7B9%5E2-80%7D%7D%7B2%7D%3D%5Cfrac%7B9%5Cpm1%7D%7B2%7D%5C%5Cx_1%5Cneq4%5C%5Cx_2%5Cneq5)
