Write a compound inequality to represent all of the numbers between -4 and 6. Help me please

Answer:

-4 < x < 6

Step-by-step explanation:

We need to represent all the numbers between -4 and 6, that is -3, -2, -1, 0, 1, 2, 3, 4 and 5.

They are all greater than -4. We generalize it as -4 < x (x is greater than -4).

On the other hand, 6 is greater than all of them, that is x < 6.

As we need to write it as a compound inequality, we just combine the two inequalities we have:

-4 < x < 6 (we write the x just once)

If we want to add the -4 and the 6 in the inequality, we just include them with the appropriate sign:

-4 \leq  x \leq 6

-4 < n < 6 . . . . . represents all numbers n between -4 and 6 (not inclusive).

Solve for the variable a D =a+b-c/3
yuradex [85]
Hey there,
solving for a is just like you think of all other letter as a constant
i.e the only variable is a
so you need to subtract b as a start
      d=a+b-c/3
-b             -b
=============

    -b+d=a-c/3                now it's time to add c/3 (isolate a by itself in one side)

     -b+d=a-c/3
+c/3         +c/3
==============
c/3-b+d=a

Hence you have solved for a

On a map, 9 cm represents 15 miles. If the distance between two cities on the map is 15 cm, how many miles separate the cities?
torisob [31]

Answer:

15 cm on the map is equal to 25 miles.

Step-by-step explanation:

Given that,

On a map, 9 cm represents 15 miles.

The distance between two cities is 15 cm. We need to find the distance in miles.

9 cm = 15 miles

1\ cm=\dfrac{15}{9}\ \miles

So, 15 cm is equal to,

15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles

So, 15 cm on the map is equal to 25 miles.

1/4x+17=x-4<br> help me and don't answer if you not gonna be serious
iogann1982 [59]
X = 28

1/4+17=x-4
Multiply both sides of the equation by 4
X+68=4z-16
Move variable to the left hand side and change its sign
X-4x+68=-16

X-4x=-16-68
Combine like terms
-3x=-16-68
-3x=-84
Divide both sides by -3
X=28

Which describes the slope of the line that passes through the points (2,5) and (-4,5)?
Stella [2.4K]
Negative because if you mark it on the graph they go in a downwards line which would be a negative slope on the graph :)
