I think it’s x>=-3
That means greater than or equal to btw :)

Answer: The answer is $[-3,\infty).$

Step-by-step explanation: We are given to find the domain of the function that is graphed in the figure.

We can see from the graph that the values of x will give the domain and the corresponding values of y will give the range of the function.

Since the values of x does not go beyond -3 on the negative X-axis and it goes to infinity on the positive X- axis, so the domain will be greater than or equal to -3.

Thus, the required domain is $[-3,\infty].$

The correct option is A): "30%" because<span> suppose vendor bought 100 ltr milk at 10/ltr so cost price =1000 rs.
In that he adds "x" ltr of water in order to get profit of 30% above cost price , means his total earnings from adulturated solution will be 1300 rs.</span>

Find the value of 5w+1 given that 7w-7=7.

Katyanochek1 [597]

Answer:

lets find the exact value of w

7w - 7 = 7

+7 +7

7w = 14

/7 /7

w = 2

Now let's replace w with 2

5(2) + 1 = 11

The table shows how the time it takes a train to travel between two cities depends on its average speed.

Ivahew [28]

Answer:

$y=\frac{160}{x}$

Step-by-step explanation:

The table shows how the time it takes a train to travel between two cities depends on its average speed.

function models the time, y, in hours, that it takes the train to travel between the two cities at an average speed of x miles per hour

y represents the time

and x represents the average speed

WE know distance = speed * times

LEts find the distance using the table

distance = 32* 5= 160

40*4= 160

50*3.2 = 160

Time = distance / speed

times is y , distance is 160 and speed is x

$y=\frac{160}{x}$

The answer to #2?? I already have the graph but I still need the answer

Sidana [21]

If we have

y = 6x + 1 and x - y = 11, we can take advantage of y - y = 0 as follows:
Subtract x from both sides of the 2nd equation:
-y = 11 - x

Now combine

y = 6x + 1
-y = 11 - x
--------------
0 = 5x + 12. Solving for x, x = -12/5. Using the equation above, find y:
-y = 11 - x
= 11 - (-12/5)
= 55/5 + 12/5 = 67/5

Then the solution is (-12.5, 67/5).

Hunter is bisecting the angle shown. When drawing the arcs centered on points P and Q, why must he keep the compass the same wid

S_A_V [24]

Answer:

The arcs are drawn to find a point on the bisecting ray. If the arcs are the same width, it makes sure that they are equidistant from the points on the rays of the angle. This causes the point to be on the bisecting ray.

Step-by-step explanation:

Bisection of an angle implies dividing the angle into two equal parts. The ray that divides the angle is called a bisector.

The hunter should use the same radius or width to draw the two arcs, using points P and Q as the center interchangeably, so that they would intersect at an equidistant point to P and Q. The point of intersection lies on the bisecting ray of the angle.
