Answer:
(−a+b)(−c+d)
=(−a+b)(−c+d)
=(−a)(−c)+(−a)(d)+(b)(−c)+(b)(d)
=ac−ad−bc+bd
Answer:
B) She is incorrect because when substituting 2 for m the result was a false statement
Step-by-step explanation:
Answer:
-23
Step-by-step explanation:
x = -5 lies in the last piece
h(-5) = 4(-5) - 3
= -20 - 3
= -23
Answer:
Gertrude's favorite is <em>George Burn</em>
What we know from the beginning:
<u>Comedians</u>:
- George Burn
- Jack Benny
- David Letterman
- Jerry Springfield
<u>Lucy</u>: Jerry Springfield is her favorite
<u>David</u>: Does not like David Letterman
<u>Gertrude</u>: Does not like David Letterman, Does not like Jack Benny anymore
Solving:
- Since we know that <em>Jerry Springfield is Lucy's favorite</em>, he is not longer an option. This leaves George Burn, Jack Benny, and David Letterman.
- David and Gertrude do not like <em>David Letterman</em>, so he must be <em>Jose's favorite</em>. This leaves George Burn and Jack Benny
- Gertrude does not like Jack Benny anymore, so the only one left to be <em>her favorite is George Burn</em>
y = 1.4x - 4.8
the equation of a line in ' slope - intercept form ' is
y = mx + c ( m is the slope and c the y- intercept )
the partial equation is y = 1.4x + c
to find c, substitute (2, - 2) into the partial equation
- 2 = 2.8 + c ⇒ c = - 2 - 2.8 = - 4.8
y = 1.4x - 4.8 is the equation in slope- intercept form
