Answer:
-14-6=-20
Step-by-step explanation:
the negative sign gives you a negative 6, which you can subtract from -14, giving you -20.
The slope, or gradient, of the line is 6/-3 which is -2. The gradient is -2.
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
I would say c as the answer
<span>To figure the amount of tropical fish in the aquarium you multiple length*height*width to find the cubic centimeters of the tank, then divide that number by 10,000. 60*50*30=90,000 cubic centimeters. 90,000/10,000=9. 9 tropical fish could be places in a tank with those dimensions.</span>
