8.9mm/10 = 0.89cm. since 10mm is 1 cm.
<span>If x represents the year then that implies that y is equal to the number of new diseases every year.
Therefore in order to solve this equation you need to input x.
y= -2(15)^2 + 36(15) +6
Now solve, but please remember to use PEDMAS order in order to solve this problem.
P= Parentheses
E= Exponents
D = Division
M= Multiplication
A= Addition
S= Subtraction
So solve the parentheses first
y= -30^2 + 540 + 6
Now the exponent.
y= 900 + 540 + 6
Now add them all together.
y= 1446
So 1,446 is the number of new cases in year 15.
y=</span>
Answer:
3.
Step-by-step explanation:
f(-2) = 3(-2)^2 + 4(-2) - 1
= 12 - 8 - 1
= 3.
Answer:
-3
Step-by-step explanation:
Let x = number of students in each of the remaining rows
266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
