ExtremeBDS [4]

Answer:

Slope

Math help please (question 2)
Alex
X>_0 y>_-4 your domain is the opposite of whats inside of the radical, in this case it’s zero but if the number was -5 you would say x>_ 5. Your range is whatever number is in the back, which is negative 4. But you have to pay attention, if there is a negative before the radical your range will be y<_ the number. But here, there isn’t a negative sign in the front of the radical so it’s just y>_ -4.

Len [333]

Answer:

x\le \:-\frac{20}{21}

Step-by-step explanation:

-3\left(9x+20\right)\ge \:15x-20\\\\\mathrm{Expand\:}-3\left(9x+20\right):\quad -27x-60\\-27x-60\ge \:15x-20\\\\\mathrm{Add\:}60\mathrm{\:to\:both\:sides}\\-27x-60+60\ge \:15x-20+60\\\\\mathrm{Simplify}\\-27x\ge \:15x+40\\\\\mathrm{Subtract\:}15x\mathrm{\:from\:both\:sides}\\-27x-15x\ge \:15x+40-15x\\\\\mathrm{Simplify}\\-42x\ge \:40\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\left(-42x\right)\left(-1\right)\le \:40\left(-1\right)

Simplify\\42x\le \:-40\\\\\mathrm{Divide\:both\:sides\:by\:}42\\\frac{42x}{42}\le \frac{-40}{42}\\\\Simplify\\x\le \:-\frac{20}{21}
