Answer:
x=9.5, y=5.75
Step-by-step explanation:
2x-5=14, 3x+2y=40
focus on 2x-5=14 first:
2x-5=14 (add 5 to both sides) 2x=19(divide both sides by 2) x=9.5
Now subtitute x into the second equation and find y:
3(9.5)+2y=40(simplify) 28.5+2y=40(subtract 28.5 on both sides) 2y=11.5(divide both sides by 2) y=5.75
Answer:
y = 3x - 10
Step-by-step explanation:
It's not an option, but you already said in the instructions that the y-intercept is -10.
y = mx + b
M is the slope and b is the y-intercept.
Answer:
![8^{-6}](https://tex.z-dn.net/?f=8%5E%7B-6%7D)
Step-by-step explanation:
![8^2*8^{-8}](https://tex.z-dn.net/?f=8%5E2%2A8%5E%7B-8%7D)
Using the exponent laws, when you multiply exponents with the same base, you add the exponents and keep the base the same.
