C
substitute a = - 1 into the expression
- (- 1) - 12(- 1)² = 1 - (12 × 1 ) = 1 - 12 = - 11 → C
42 drank iced tea
60 drank either water or lemonade
So the ratio would be 42:60 or 7/10 as a fraction.
So D is the correct answer
Answer:
12
Step-by-step explanation:
560-500=60
60/500*100=12
<h3>Of the four listed equations, B is the only equation that is not linear.</h3>
A linear equation is any equation that results in a straight line, as each value is a fixed number from the previous.
In a non-linear equation, a variable is being raised to a power, which results in a curved line.
change in y/change in x
y2-y1/x2-x1
-1--5/0-2
-1+5/-2
4/-2
-2
slope is -2
now take one ordered pair and plug it into the equation (for this example i will use the SECOND ordered pair
y = -2x +b
-1 = -2(0)+b
-1 = b
the equation is
<h2>
y = -2x - 1</h2>
