Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7
I'd say 50% because out of 6 numbers 3 of them are odd.
2 fourths is a half so multiply 2 by 3 to get your answer that is 6
Okay. So, the line shaded would have to be left to 2, because it's less than 2. In that case, A and C are eliminated, because they shade to the right, not left. B and D do this, but wait. The dotted line has to represent the less than, because the one that's fully filled in would mean less than or equal to. B would make sense, because the line is dotted and that makes an inequality symbol of less than, not less than or equal to. The answer is B.
Note: When the sign is < or >, the line on the graph is dotted. If the sign is <= or >=, then the line on the graph is solid.
using the FOIL method the equation gets pretty long
Multiply each term by each term and combine like terms the given equation simplifies to:
f(x) = -2x^5 - 9x^4 - 8x^3 + 15x^2 +28x + 12
The degree is equal to the highest exponent, which is the 5 on -2x^5
The degree is 5
The y intercept is the value of y when x is 0
Replace all the x's with 0 and solve the equation:
f(x) = -2(0)^5- 9(0)^4 - 8(0)^3 + 15(0)^2 +28(0) + 12
= 0 -0 -0 + 0 +0 +12 = 12
The y intercept is (0,12)
