Answer:

A) y+5=-3/2(x-4)

Step-by-step explanation:

Start by rewriting the equation A into slope intercept form (y=mx+b).

1) Distribute the -3/2 to x and -4:

y+5=-3/2x+6

2) Subtract 5 from both sides:

y=-3/2x+1

Now lets check to see if the equation matches up with the line...

The slope (-3/2) is correct, because every time you go down three, you go across to the right 2!

We also know the y intercept, (1) is correct, because the line crosses the y axis at the point (0,1)

Therefore, the correct answer is A!

The function f(x) is shown on the graph.
stellarik [79]
Given :
On a coordinate plane,a curved line with 3 arcs, lab led f of x, crosses the x-axis at (negative 2,0), (negative 1,0), (1,0), and (3,0) and the y axis at (0, negative 6).

To find:
f when x = 0. i.e. f (0).

Solution:
since the graph has 3 arcs and 4 solutions, it can be visualized as the follows:
Between each solution, the function has to increase and decrease giving arcs in between.
1. One of the arcs is between (negative 2,0) and negative (1,0)
2. Second arc is between (negative 1,0) and (1,0)
-this arc cuts the y axis, since x= 0 lies between x= -1 & x=1-
3. Third arc is between (1,0) and (3,0)
Therefore only the 2nd arc cuts the y axis
It’s given that the curve cuts the y axis at (0, -6)
That is when x= 0, f(0) =-6
Therefore the value of f (0) is -6 only.

A salesperson is driving from the office to a client, a distance of about 250 kilometers. After 45 minutes, the salesperson pass
ludmilkaskok [199]
<span> <span>Speed is calculated as distance covered, divided by the time taken to cover that distance. In this case, the sales person covered 50KM in 45minutes (which can also be expressed as 3/4 hours). To calculate the speed he used to cover this distance, we divide the distance covered by the time taken. So 50km/3/4hours. This gives us 66.67km/hr. In order to calculate the amount of time the salesperson used to travel from the office to the sales person, we calculate as follows 250km/66.67km/hr. This gives us a total of 3.75 hours or 3 hours 45 minutes.</span></span>
