−6 <3n+9 <21. whats the solution

Mathematics
1 answer:
tester [92]3 years ago
5 0

We have

-6 < 3n+9 < 21.

From this we have system of inequality

-6 < 3n+9 \\3n+9 < 21

We have to simplify both inequalities

3n+9 > -6 \Longrightarrow n > -5 \\3n+9 < 21 \Longrightarrow n < 4

So we can conclude that

n > -5 \wedge n < 4 \Longrightarrow x\in(-5,4)

Hope this helps.

What are the coordinates of the x-intercept(s) of the graph of y=(x-6)(x+5)
MissTica

Answer:

(-5 , 0) and (6 , 0)

Step-by-step explanation:

In order to get the coordinates of the x-intercept(s) of the graph of y=(x-6)(x+5)

we need to solve for x the equation (x-6)(x+5) = 0

(x-6)(x+5) = 0

⇌

x - 6 = 0  or  x + 5 = 0

⇌

x = 6  or  x = -5

therefore

the coordinates are :

(-5 , 0) and (6 , 0)

2. Elsewhere on the sketch, draw a line and create a point on the line . Label the point P.

3. Select point P and line segment XY.  Construct circle by center and radius.

4. Select the circle and line, then construct point of intersection. Label one of the points of intersection point Q.

5. Select point P and point Q.  Construct segment PQ.

6. Select the circle, line, and other point of intersection.  Hide objects.  Only segment XY and segment PQ should be visible on the sketch.

7. Try dragging point X.  Segment PQ should lengthen and shorten as segment XY does.

the national flag of scotland has a white diagonal on a blue backround Tracy is sewing a scottish flag she knows that the length
dybincka [34]

Answer:

12 feet

Step-by-step explanation:

By Pythagoras theorem, a²+b²=c², where c represents the diagonal and a and b represents the other sides of a right angled triangle

As a flag is a rectangle, the two triangles cut would be  right angled triangles

Therefore, a²+9²=15²

a²+81=225

a²=144

a=√144

a=12 feet
