4x²-5=3x+4
4x²-3x-9=0
x=(3±√((-3)²-4*4*-9))/2*4
x=3±√(9+144) /8
x=(3±√153) /8
x=⅜±√153/8
8z-8=6z+8
8x-6z=8+8
2z=16
Z=8
The given terms can be divided into two sections. First section is for the numbers and the second one for the letters.
1st section: 1, 2, 3, and 4
2nd section: I, L, F
I is the 9th letter in the alphabet, L is the 12th letter, and F is the 6th letter in the alphabet.
The pattern observed:
I to L: 12 - 9 = 3
L to F: 6 - 12 = -6
Next letter should be +9. This means that the letter should be 9 places higher than F. The letter should be O which is the 15th letter.
Answer:
The first one or the 2nd one, since it says NOT worth half, I would say the first one is the answer.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
For it to be a function, every x value must have 1 unique y value ONLY.
In option A, you can see that the x value of 1 has 2 y values, 1 & 5. So it's not a function.
In option B, you can see that the x value of 0 has 2 y values, 0 & -4. Moreover, the x value of 4 also has 2 y values, 2 & -2. So it's not a function.
In option C, you can see that the x value of -2 has 2 y values, 4 & -4. This is not a function as well.
In option D, each x value has a unique y value that are different. So this is a function.
Answer is option D.
