Answer: OPTION B.
Step-by-step explanation:
1. By definition, the line intercepts the x-axis when y=0. Therefore, you must susbtitute y=0 into the equation of the line given in the problem and solve for x, as you can see below:
2. Knowing that the x-intercept of the line from the equation and is -2 and the x-intercept from the description is (0,0), you can conclude that the correct option is B.
6x+6y=1500 like this i think
Answer: 48
Step-by-step explanation:
l = w + 7
2w + 2l = 178
2w + 2(w + 7) = 178
2w + 2w + 14 = 178
4w = 164
w = 41
l = w + 7
l = 41 + 7
l = 48
For this case we have the following exponential function:
The first thing you should see for this case is the behavior of the function when you substitute values of x.
When replacing positive values (very large) the function tends to infinity because it is an exponential function.
When substituting negative values (very large) the function tends to zero because it is an exponential function.
Therefore, the range of the function is:
(0, ∞)
Equivalently:
y > 0
Answer:
all real numbers greater than 0
