Answer:
48
Step-by-step explanation:
We need to find the multiples of 8
8,16,24,32,40,48
48 is between 45 and 50 so he must have bought 48
Answer:
[0] real zeros
Step-by-step explanation:
You can use the discriminant of the quadratic formula which is b² – 4ac to determine the # of real zeros by knowing that:
- 2 real zero(s) occur when b² – 4ac > 0.
- 1 real zero(s) occur when b² – 4ac = 0.
- 0 real zero(s) occur when b² – 4ac < 0.
The data cannot be modeled by a linear equation because the rate of change is not constant. This can be seen in the fact that when you increase x from 1 to 2, you subtract 3 from the y-values. However, as you add 2 more, you continue to subtract 3 from the y-values. If the function were a linear function, we would likely subtract 6 from the y-values, since that would form a constant ratio.
You can even look at the fact that as we increased the x by 4, we continued to decrease the y by 3. This does not form a constant ratio, and is thus the data could not be modeled by a linear function.
Answer:
Step-by-step explanation:
<u />
13 × 9w = 13 × 
117w = 5w - 6 + 13
117w = 5w + 7
117w - 5w = 5w - 5w + 7
112w = 7
112w ÷ 112 = 7 ÷ 112
