Answer:

<h2>C) The two functions have the same x-intercept.</h2>

Step-by-step explanation:

The given function is

3x+2y=12

Let's analyse this function. We can its elements, that is, its slope and y-intercept points by isolating y, as follows

3x+2y=12\\2y=12-3x\\y=\frac{12-3x}{2}\\ y=-\frac{3x}{2}+\frac{12}{2}\\  y=-\frac{3x}{2}+6

So, the y-intercept is at y=6, which is not the same point showed in the graph. The slope of the linear equation is -3/2, which is not the same slope showed in the graph.

From the graph, we can deduct that te y-intercept is at y=4, and the slope is 1, because both variables increase at the same rate, which is 4 units, and if you divide 4/4 = 1.

At last, if we calculate the x-intecept of the linear equation, it would be

For y=0, let's find x

3x+2y=12\\3x+2(0)=12\\x=\frac{12}{3}\\ x=4

This means the x-intercept of the linear equation is at 4, and the graph shows the same x-intercept.

Therefore, the two functions have the same x-intercept. So, the right answer is C.

Well for problems like this you need to look at what is plotted. And you need to look at the y intercept which is the vertical line and the x intercept which is the horizontal line. I think the answer is B because of what is plotted. I am not 100% sure but I think it is. Let me try to look into it more but what is this for? Hw assignment?

Rancher juan wants to enclose a rectangular area beside a river. there are 240 yards of fencing available. what is the largest t
Zielflug [23.3K]
Perimeter = 2L + 2W →  240 = 2L + 2W  →  120 = L + W  → 120-L = W
Area = L x W  → Area = L(120-L)  →  Area = 120L - L²
Find the derivative:
dA/dL = 120 -2L → 0 = 120 - 2L → L = 60

Area = 120L - L² = 120(60) - (60)²  = 7200 - 3600 = 3600

The maximum area is 3600 yds²

The strategy is called expanding notation because you are expanding that problem into small equations :)
