she drove 40 mph & 60 mph
60 +40 = 100
100/2 = 50
so she drove an average of 50 mph
Answer:
According to steps 2 and 4. The second-order polynomial must be added by 
and 
to create a perfect square trinomial.
Step-by-step explanation:
Let consider a second-order polynomial of the form 
, 
. The procedure is presented below:
1) (Given)
2) 
(Compatibility with addition/Existence of additive inverse/Modulative property)
3) 
(Compatibility with multiplication)
4) 
(Compatibility with addition/Existence of additive inverse/Modulative property)
5) 
(Perfect square trinomial)
According to steps 2 and 4. The second-order polynomial must be added by and to create a perfect square trinomial.
This is what I learned:
D = Divide
M = Multiply
S = Subtract
B = Bring down
C= Check
D= Dad
M= Mom
S= Sister
B= Brother
C= Cousin
Hope this helped you! :)
Answer:
D
Step-by-step explanation:
Because the numbers do not comply with the like 11+6+18+21= no answer and multiplying them all didn't matter either so its none of the above
Answer:
Step-by-step explanation:
4x > -16 reduces to x > -4: All numbers greater than x = -4 (shaded area to the right of -4).
6x < -48 reduces to x < -8: All numbers to the left of -8 (shaded area to the left of -8).
Solution: (-infinity, -4) ∪ (-8, infinity)
The number line between -8 and -4 is not part of the solution set (is not shaded or darkened)
Draw an open circle at -8 and extend an arrow to the left of this circle. Then draw an open circle at -4 and extend an arrow to the right of this circle.
