Answer:
avoid contact with blood, semen or other body fluids
Explanation:
The system would equal (1.65,-0.25)
You can use substitution for this. But first we need to put one of the equations into the value of y or x. We can use 5x+y=8 and solve for the value of y. Subtract 5x on both sides and you’ll get the value of y which will look like y=-5x+8.
Next substitute in y for 5y in 5x+5y=7 so that you get 5x+5(-5x+8)=7. Next distribute and you’ll get 5x-25x+40=7, add like terms and you’ll get -20x+40=7. Next you want to subtract by 40 on both sides and you’ll get -20x=-33. Isolate x by dividing by -20 on both sides and you’ll get x=33/20 or 1.65.
Next that you have the x value solve for y by plugging in 1.65 for x in 5x+y=8 and you’ll get 5(1.65)+y=8, distribute and subtract 8.25 on both sides and it will leave you with y=-0.25.
Do you have the answer choices? Typically, it would be pouring the required amount into the bottle cap and then transfer them to the medication cup. Has the least risk of contamination for both the meds in the cup and in the bottle.
