F(x)=1-x² and g(x)=√(11-4x)
(g+f)(2)=>
1-(2)²+√(11-4(2))
=√3-3
(f/g)(-1)
(1-(-1)²)/(√(11-4(-1))
=0
(g-f)(-1)
√(11-4*-1)-(1-(-1)²
=√15
(g×f)(2)
1-(2)²×√(11-4(2))
-3√3
Answer:
x < - ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
Step-by-step explanation:
Given
- 15 - 2x > 6x + 4 ( subtract 6x from both sides )
- 15 - 8x > 4 ( add 15 to both sides )
- 8x > 19
Divide both sides by - 8, reversing the symbol as a consequence of dividing by a negative quantity, thus
x < - ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
Answer:
k ≥ 13/5 or k ≥ 2.6 ( same thing )
Step-by-step explanation:
symbol stays the same throughout (≥)
subtract 6 from both sides of the symbol ( 13 ≥ 5k)
divide both sides by 5 (13/5 ≥ k )
your answer can be written as k ≥ 13/5 or k ≥ 2.6
Answer:
X=15
Step-by-step explanation:
A +B + C = 180
2x +4x+ 6x = 180
12x =180
X= 15
