Answer:
A line -5x +4y = 25 has a slope 5/4
when the lines are parallel slope is equal.

The reference angle is the angle made with the x-axis. For two points to have the same reference angle, they would need to have the same absolute value of their tangents = y/x.
For the first pair of points: the first point has a tangent value of 1/sqrt(3), while the second has a tangent value of sqrt(3), so these are not identical.
For the second pair of points: the first point has a tangent value of -sqrt(3), while the second has a tangent value of -1/sqrt(3), so these are
not identical.
For the third pair of points: the first point has a tangent value of sqrt(3), while the second also has a tangent value of sqrt(3), so these have the same reference angle.
For the fourth pair of points: the first point has a tangent value of
1/sqrt(3), while the second has a tangent value of sqrt(3), so these are
not identical.
So the only correct answer is the third choice.
Answer:
22 fish
Step-by-step explanation:
cella has 12 fish. micheal has ten more 12+10=22. combind 22+12=34
I'm going to set up an equation to find the amount of momey Elisa has, then we can check our answer
e + 2e + 2e + 5 + 2e + 5 · 3 + e + 2e = 69
Simplify:
10e + 30 = 69
Subtract 35 from each side:
10e = 39
Divide by 10 on each side
e = 3.9
We can check our answer by putting the value in the simplified equation.
10 · 3.9 + 30 = 69
Yep! The equation is correct. Now for the answer.
Elisa
3.9
Jacob
7.8
Sandra
12.8
Damian
38.4
Martin
11.7
