It products x^2 - 49. the answer is the second one
Lena [83]3 years ago
3 0

Answer:

X^2-49  is the correct option

Step-by-step explanation:

(x+7)(x-7)

x*x-7x+7x-7*7

x^2-49

The product of both gives x^2 − 49

which implies that option last option is wrong x^2+49 since the sign in between is negative sign

The option x^2 + 14x + 49  is also wrong because the -7x+7x gives zero not 14

The first option is also wrong because -7x+7x gives zero not -14

All in all, the correct option is x^2+49, the second option

What is the correct truth table for ~p^~q?
Kisachek [45]
This symbol - ~ - is the "not" symbol, which means the opposite.  So I think were given values for p and q?  If so, you just reverse the p values to get ~p (true becomes false or 1 becomes 0 or yes becomes no).  
This symbol ^ is the "and" symbol.  That means that you need to figure out if both ~p and ~q are true.  If so, your result is true (or 1 or yes, depending on which the problem uses).  Otherwise, your result is false (or 0 or no) for each corresponding ~p and ~q value.

Write rule for the linear function in the table
ivann1987 [24]
The generic equation is:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)
 m = (0-1) / (4-3)
 m = (- 1) / (1)
 m = -1
 The ordered pair is:
 (xo, yo) = (4, 0)
 Substituting values:
 y-0 = -1 * (x-4)
 y = -x + 4
 Answer:
 
y = -x + 4
