Since we are only given with a single point and we are given a proportional relationship, then we can make the assumption that when one variable is 0, the other is also 0. So, we can make the equation:
y/x = 4 / 20 or
y = x/5
B) 12 miles and 12 gallons. The answer is B because gallons and miles are 2 completely different types of measurement. If you look at A, C, D, they all have the same measurements. I hope this helped!
Answer:
Step-by-step explanation:
6b + 7 + 4b - 1 =
10b + 6 <===
What you must do for this case is find a function that suits the problem and graph it.
We have:
y: the number of bales in the barn
x: days feeding his cows.
y = -4x + 60 see graphic attached.
First, fint the roots of the equation
1.
2. You can see that this equation has two different real roots. Note that you can make this statement without finding roots, only knowing the value of discriminant: since D=81>0, then the equation has two different real roots.
