F(x) = -2 + 8

f(x) = 6

No matter what x is, it does not change the value of f(x).

f(-1,8) = 6

Answer: 6

Answer:

Option B, 6

Step-by-step explanation:

If f(x) = -2 + 8 then we have to calculate the value of f(-1.8)

Since f(x) = -2 + 8 = 6 is a constant.

Then for any value of x, f(x) will remain constant

therefore, f(-1.8) = 6

Option B, 6 is the answer.

Ronnie misses the school bus 1 out of every 30 school days. He sets up the proportion 1/30=180/x to predict how many days he wil
bija089 [108]

Answer:

1/30=x/180

Step-by-step explanation:

The way that Ronnie wrote his proportion is wrong since 180/x is saying that he will miss 180 days of school. The fraction 1/30 means that he would miss 1 day out of 30 days, which is correct. But the fraction 180/x would mean that he is missing 180 days of school, which is wrong.

Solving:

1/30=x/180

180/30=6

1 x 6 = 6 days

He will miss 6 days of school in 180 days.
