Answer:
Equilateral triangles can have only acute angles because acute angles means less than 90° so every angles in equilateral triangle have 60°
3 is always on the numerator. It is not effected by a power. The answer has to be something that leaves the numerator alone. That means that B is not correct.
The answer is going to be something that makes the denominator 1 when n = 1. That's going to be the answer to the question, because the first term in the sequence is just 3. The denominator must be 1. (not zero).
D is not the answer, because 3/5^1 = 3/5, so D is wrong.
A is not going to get us anywhere either. 3/5^(1 + 1) = 3/5^2 = 3/25 which is not the first term.
The only choice we have left is C. It must be the answer. 3/5^(1 - 1) = 3/5^0 = 3/1 = 3. There's your answer. Note anything raised to the zero power = 1.
On a graph you can use rise/run
Or you can use y^2-y^1/x^2-x^1
Answer:
a. y = -x + 2
b. (2,1)
Step-by-step explanation:
a. Looking at the graph, we can see that the slope is negative
this is because what we have is a falling graph
secondly, the y-intercept is positive
So the correct equation would be a negative value for slope and positive value for y-intercept
so;
y = -x + 2 can be correct
option D
b) What we simply have to do is to make a substitution
Let us look at the point (2,1)
we have x= 2 and y = 1
Thus,
3(1) = 2(2) - 1
3 = 4-1
3 = 3
That means that the point (2,1) lie on the line
