Step-by-step explanation:
Wehn dealing with order of operations, we can remember the expression PEMDAS, which stands for parentheses, exponents, multiplication, division, addition, and subtraction.
So, our first step in the above problem is the parentheses:
The second step is exponents:
The third step is multiplication:
The fourth and final step is addition:
Answer:
Step-by-step explanation:
A line is perpendicular to another if its slope is the negative reciprocal of the other.
Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope . The negative reciprocal of that is , which is the slope of the third answer choice.
There are 50 total patrons. 16 like lattes, 12 like espressos, and 8 like both drinks.
Add the two totals for patrons that like either lattes or espressos:
8 patrons like both drinks, so subtract this from the amount of patrons that like either drink:
20 patrons like at least one drink.
Subtract the amount of patrons that like a drink from the total amount of patrons:
30 patrons like neither drink.
