Answer:
Step-by-step explanation:
We want to find the x-intercepts of
At x-intercept, y=0.
Take sine inverse of both sides to get:
The x-intercepts are:
for n being an integer
Answer:
x=18y+5
Step-by-step explanation:
Answer:
The 3rd option
Step-by-step explanation:
To prove that 2 triangles are similar, we need to prove that 2 pairs of their angle measurements are congruent.
This is because all triangles have 180 degrees, so if 2 pairs are congruent, the remaining angles will also be congruent
We know that m<D=m<E
We also know that m<DCA=m<ECB because they are vertical angles.
Vertical angles are always congruent.
Therefore, the triangles are similar.
The correct similarity statement would be 1, since <D corresponds with <E.
Now let's look at the 3rd Statement. To prove that two lines are similar, we would have to prove that their alternate interior angles are congruent.
A pair of alternate interior angles would be <D and B or or <E and <A
There is no way to prove this, since we do not know any of the angle or that measurements or if the triangles are isosceles triangles.
Hence, the correct choice would be 1 only.
To solve for a variable means to ISOLATE the variable on one side of the equation. To do so, divide both sides by the coefficient of y.
Look:
2y/2 = (-x+7)/2
Answer: y = (-x + 7)/2
The answer can also be written as
y = -(x/2) + (7/2)
Both answers mean the same thing.
