Find the inequality represented by the graph.

Mathematics
1 answer:
Rainbow [258]3 years ago
5 0

Answer:

y>-2/3x+3

Step-by-step explanation:

Looking at the line, we notice that the y-intercept is 3, and the slope is -2/3, so using that information, we find the slope intercept form of the inequality, which is y(?)-2/3x+3 (the question mark is where the inequality symbol will be).

Looking at the line again, we see that it is shaded above (not below), so y is greater than the other side of the inequality.

Looking at the line AGAIN, we see the graph has a dashed line (not solid), so we are not dealing with an "or equal to" inequality.

Therefore, we should use the greater than symbol, creating the answer y>-2/3x+3.

A pizza dlivery car can travel 11 km for every gallon of gasoline it uses. If the driver's average speed is 28 km/h, how many ho
Svetlanka [38]

Answer:

13.75 hours

Step-by-step explanation:

First, find how many km the driver can travel:

11(35)

= 385

Then, divide this by 28 to find how many hours the driver can travel:

385/28

= 13.75

So, the driver can travel 13.75 hours

Which equation gives the value of the circumference, C, of a circle with a diameter of 56 feet?
Alik [6]

Answer:

C=\pi (56)

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter

in this problem we have

D=56\ ft

substitute

C=\pi (56) -----> equation that give the value of the circumference

C=56 \pi\ ft

AC has endpoints<br> A(3,7) and C(6,11).<br> Find AB if B is the<br> midpoint of AC.
faltersainse [42]

Answer:

d=2.5

Step-by-step explanation:

first find the coordinate of B(mid point of AC):A(3,7) C(6,11)

d=√(6-3)²+(11-7)²

d=√3²+4²

d=√9+16=√25=5

since B is the mid point : d/2=5/2=2.5

<h2>Another way :</h2>

B(x1+x2/2 , y1+y2/2)   , x1=3 , x2=6, y1=7, y2=11

B(9/2,18/2)

B(9/2,9)

Find AB : the length or distance between 2 points:

d=√(x2-x1)²+(y2-y1)²

d=√(3-9/2)²+(7-9)²

d=√(-3/2)²+(-2)²

d=√1.5²+4

d=√6.25

d=2.5

What is the solution of x-1/1-x &lt; 0?
kykrilka [37]

Option C is correct option.

Step-by-step explanation:

We need to find the solution of \frac{x-1}{1-x}

The given inequality becomes undefined when x = 1 because the denomiator is: 1-x and if x = 1 then it becomes 1-1 = 0 and anything divided by zero is undefined.

So, all values other than 1 are included in the solution of the given inequality.

So, solution is: x<1 or x>1 but x≠1

So, Option C is correct because all numbers are included in number line except 1. An unfilled circle on 1 shows that it is not included in the solution. Rest of numbers are included.

Option C is correct option.
