Answer:
Its 6x8+9 so its 7
Step-by-step explanation:
So bscily you divide 8 by 4 its 2 and 2x3 is 6+1=7 there you go buddy
Answer:
Step-by-step explanation:
( g ° f )(x) = ( x + 7 )² = x² + 14x + 49
20 + 3(x² + 14x + 49) = - 34
20 + 3x² + 42x + 147 = - 34
3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0
D = 196 - 268 = - 72 < 0

Answer:
slope = - ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
The equation of a line in slope0 intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x + 9 ← is in slope- intercept form
with slope m = - ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
