B + 4(b) - (8) ➡0
~Add the number 8 to each of the sides of the equations that you're working with ⬇ ~
5(b) - 8 ➡0
~Now, you have to divide 5 by each of the sides to the equation⬇~
B = 8 ÷ 5 = 1.6
So,your answer might be 1.6
Answer:
the answer is D no solution
Answer:
60
Step-by-step explanation:
substitute x=8
f(8)=(8)2-4=60
Answer:
1)
, 2)
.
Step-by-step explanation:
1) The ordered pair of the parabola is:
![f(0) = 0^{2} - 6\cdot (0) -27](https://tex.z-dn.net/?f=f%280%29%20%3D%200%5E%7B2%7D%20-%206%5Ccdot%20%280%29%20-27)
![f(0) = -27](https://tex.z-dn.net/?f=f%280%29%20%3D%20-27)
![(x,y) = (0,-27)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%280%2C-27%29)
2) The quadratic function needs to be rearranged into the standard form:
![y = x^{2}-6\cdot x -27](https://tex.z-dn.net/?f=y%20%3D%20x%5E%7B2%7D-6%5Ccdot%20x%20-27)
![y = x^{2} - 6\cdot x + 9 -9 -27](https://tex.z-dn.net/?f=y%20%3D%20x%5E%7B2%7D%20-%206%5Ccdot%20x%20%2B%209%20-9%20-27)
![y = (x-3)^{2}-36](https://tex.z-dn.net/?f=y%20%3D%20%28x-3%29%5E%7B2%7D-36)
![y + 36 = (x-3)^{2}](https://tex.z-dn.net/?f=y%20%2B%2036%20%3D%20%28x-3%29%5E%7B2%7D)
