Answer:
the slope is b: -1/2
rise/run is an easy way to do it. Count the number of x-units between points and the number of y-units. in this case its 6 x-units and 3 y-units. y is rise and x is run, so it'll be 3/6 or 1/2 and it's negative because it's decreasing left to right.
Answer:
d
Step-by-step explanation:
I got it right on my quiz
For this case we are going to do a small step-by-step study of the given functions.
1) Option A is discarded because by substituting x = 0 in the given equation, the result is positive, which does not agree with the graph.
2) Option B is discarded because when substituting x = 0 in the given equation, the root is negative and the result will be an imaginary number.
3) Option C is discarded because when substituting x = 0 in the given equation, the result is positive, which does not agree with the graph.
4) Option D is the correct one:
When replacing x = 0 we have:
This result agrees with the graph shown.
Answer:
Option D.
1)inside the triangule is 180º .There are 3 angules, one with 120º, theta and
angle ACB, lets call it x.
x + theta + 120 = 180
x + theta= 180-120
x + theta= 60
x= 60- theta
angle ACB= 60- theta
Answer: Choice D
9, 30, 93, 282, 849
============================================================
Explanation:
The notation tells us that the first term is 9
The notation says that we multiply the (n-1)st term by 3, then add on 3 to get the nth term
So if we wanted the second term for instance, then we'd say
If we want the third term, then,
and so on.
The terms so far are: 9, 30, 93
You should find the fourth and fifth terms are 282 and 849 respectively if you keep this pattern going.
Therefore, the answer is choice D
