It’s A. Because if you flip it it still is the same just reflected to the other side, I’m almost positive it’s A.
Answer:
-11
Step-by-step explanation:
assuming 4x-3 = f(x) and the other equation = g(x)
(4x-3) - (x^2 +2x)
(4(4)-3) - (4^2 +2(4)
(16-3)-(16+8)
(13)-(24)
-11
A fisherman can row upstream at 4 mph and downstream at 6 mph. He started rowing upstream until he got tired and then rowed downstream to his starting point. The distance of how far the fisherman row if the entire trip took 2 hours is 9.6 miles

The speed of an object refers to the change of the object's distance within a specified time.
Mathematically, we can have;

Distance = speed × time
From the information given;
- The fisherman row upstream for 4 miles/ hour.
- The distance covered by the fisherman = 4 × t₁ ----- (1)
- The fisherman row downstream at 6 miles/ hour
- The distance covered by the fisherman = 6 × t₂ ------ (2)
- SInce it took the entire trip 2 hours, we can infer that:
From equation (2), replace the above value of t₂ into equation (2)
- d = 6 t₂
- d = 6(2 - t₁)
- d = 12 - 6t₁
From equation (1)
Equation both distance together, we have:
- 12 - 6t₁ = 4t₁
- 12 = 4t₁ + 6t₁
- 12 = 10t₁
- t₁ = 12/10
- t₁ = 1.2 hours
From t₂ = 2 - t₁
- t₂ = 2 - 1.2
- t₂ = 0.8 hours
From d = 4t₁
Replace t₁ with 1.2 hours
- d = 4(1.2 hours)
- d = 4.8 miles
Also, from d = 6t₂
Therefore, we can conclude that the distance of how far the fisherman row if the entire trip took 2 hours is (4.8+4.8) miles = 9.6 miles

Answer:
a) x(x-2)
b) 6x(2x+2)
dont know c and d sorry
Step-by-step explanation:
Answer:
b= -48
Step-by-step explanation:
by transposing,
43=59+b/3
b/3+59=43
b/3=43-59
b/3= -16
b= -16×3
b= -48
therefore the answer is b= -48
