The filling rate is 2/5=0.4 gallons per second. So the appropriate equation is A.
Answer:
1) A
2) A
3) B
4) D
5)A
6) D
7) A
8) C
9) D
Step-by-step explanation:
1) -5 (-2) -6= 4
2) 3 coins plus c coins = 3 + c
3) x-2 =16, x = 18
4)
=-5. Clearing, z = 60
5) x =13,4
6) 14=t-4. Clearing t = 58
7) -30=j+50, clearing j=80
8) 2.8x=-9.24, clearing x=-3-3
9) 5.8=
. Clearing z=12.76
Answer:
Step-by-step explanation:
When 'c' is negative both p and q would have the same sign and when opposite signs whereas when b is positive and negative, both would have positive and negative signs respectively.
<h3>How the signs affect the factored form</h3>
The ways in which the signs of 'b' and 'c' affect the form include;
- if c is negative, then p and q have opposite signs.
- If c is positive, then p and q have the same signs.
- If b is negative, both the signs of p and q would be negative.
- Also, if b is positive, then the signs of both p and q would be positive.
