Answer: Option D: R = {3, 9, 12}
Step-by-step explanation:
The range of a function is the set of the possible outputs of a function:
if we have the function f(x) = y, the values of x are the domain, and the values of y are the range.
In the image, the set at the right is the output, so the set in the right is the range.
such that we have the pairs (-2,3) (2, 3) (3, 9) (4, 12)
So the range will be R = {3, 9, 12}
Answer:
x = - 7
Step-by-step explanation:
Given
- 2(x + 5) = 4 ← distribute the parenthesis by - 2
- 2x - 10 = 4 ( add 10 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k = 
= 
= 
, thus
y = x ← equation of variation
When x = 18, then
y = × 18 = 
= 6
<span>3 tanks because he can do 400 miles on tank, and he's goin 1,100 miles, he does 400 miles with first tank, next tank he gets to 800 miles, and then he uses 3/4 of last tank to get to 1,100, he will then have 100 miles left on the tank though.</span>
