The number x ≤ 10 for the inequality (-1/5)x + 3 ≤ 1.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Negative one-fifth of the number, increased

by 3, is at most 1.

Number = x

This can be written as,

(-1/5)x + 3 ≤ 1

Solve for x.

(-1/5)x + 3 ≤ 1

(-1/5)x ≤ 1 - 3

(-1/5)x ≤ -2

x ≤ -2 x (-5/1)

x ≤ 10

Thus,

The number is less than or equal to 10.

The figure below shows a shaded rectangular region inside a large rectangle:

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is a smaller rectangle of length 4 units and width 3 units placed symmetrically inside the larger rectangle. The smaller rectangle is shaded gray.

76%
50%

A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?​

Answers

Answer:monthly rent of a 1-bedroom apartment= $280

Step-by-step explanation:

Let the  cost of 1 bed room apartment = x

And the cost of two bedroom apartment= 2x-40

Since the cost of of two bedroom apartment = $520  

Then the cost of one bed room part will be expressed as

520= 2x- 40

520+40 = 2x

560= 2x

x= 560/ 2

x= 280

Therefore the  cost of 1 bed room apartment = x= $280

Answers

Answer:

Step-by-step explanation:

A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.
