I will one only and you do the rest.
Let x = -2
Plug into given function.
f(-2) = 2 - 5(-2)
f(-2) = 2 + 10
f(-2) = 12
So, when x = -2, f(x) = 12.
Table:
x............ f(x)
-2 12
-1
0
1
2
Find the rest the same way.
Step-by-step explanation:
Since y is directly proportional to x,
we have y = kx, where k is a real constant.
When x = 15, y = 12.
=> (12) = k(15), k = 0.8.
Therefore we have y = 0.8x.
When x = 2, y = 0.8(2) = 1.6.
The answer is y = 1.6 when x = 2.
Answer: Rate > 12 miles/day
x > 12
She must run more than 12 miles each day
Mona wants to run more than 60 miles this week. She ran a total of 24 miles during the first 4 days of the week. Which number line represents the number of miles Mona must run each day if she wants to meet her goal?
answer choices
x ≥ 10
x = 12
x > 10
x > 12
Step-by-step explanation:
To complete more than 60 miles a week.
After running 24 miles during the first 4 days
We are left with (7-4) days = 3 days
And also,
(60-24) miles to complete the weekly target
> 36 miles (more than 36miles)
Therefore, the number of miles needed to cover per day in the next 3 days is given as.
Rate > distance/time
Rate > 36miles/3days
Rate > 12 miles/day
Answer:
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [-6,∞)
therefore
the answer is
The domain are all values of x greater than or equal to minus six
7 x 2/15
7 x 2 = 14
14/15 is your answer
hope this helps
