The answer is D I just took the test
Answer:
D
Step-by-step explanation:
Answer:
Step-by-step explanation:
1.Trinomial(The definition of a trinomial is a math equation that has three terms which are connected by plus or minus notations)
2.Nope because the highest degree term is on a second place(should be on first)
3.Yes
4.Yes
5.Yes
6.Yes
7.No,-3
8.Neither odd nor even
9.Neither odd nor even
Answer:
C. (3, -2)
Step-by-step explanation:
x + y = 1 ➡ x = 1 - y we can use this information in the first equation to find the value of y
3x - 5y = 19 replace x with 1 - y
3 ×(1-y) - 5y = 19 ➡ 3 - 3y - 5y = 19 add like terms
-8y = 16
y = -2 if y is 2 then x is
x + y = 1 ➡ x +(-2) = 1 and x = 3
Answer:
Population = 691.83 (rounded = 692)
Step-by-step explanation:
The equation is:
When there is no base written with log, we assume "base 10", so we can say:
Now, we need to find the population (y) when x = 12. Lets plug in 12 into x:
Now, we change to exponential form by using the formula shown below:
So, we have:
Evaluate using calculator to get:
The population after 12 years, would be 691.83, rounded, 692
