Answer: The bedroom is 5 x 5, since that is the only square measure that would make 25 (5x5) ft^2. Assuming no doors, windows, or pinups, the wall area is 120 ft^2

Step-by-step explanation:

4 walls, with no doors or windows, would be 4x (5*6) = 120ft^2

Step-by-step explanation:

perpendicular means to cross at a right angle (90 degrees).

so, any line perpendicular to the x-axis is parallel to the y-axis.

and any line parallel to the y-axis has only a defining x value. all points on that line have the same x value (while any value for y from -infinity to +infinity is valid).

the y-axis itself is

x = 0

the specified point here has an x value of 4.

so, the line we are looking for is

x = 4

to point out : this is NOT a function, because for the same x value we get more than 1 valid y values.

Answer:

X=150

Step-by-step explanation:

Answer:

Well, you first want to find out what it is in decimal form, which in this case is 0.124. Then once you do that, you can convert it to an improper fraction, which would be 124/100, you then can simplify it to convert it into a mixed number, which lands you the final answer of 1 6/25 I hope this helps you! :)

Answer:

2 x 4 − x 3 + x 2 − 9

Step-by-step explanation:

Answer:

Step-by-step explanation:

The Sum:

The difference:

Subtract the sum from the difference:

Answer:

See below.

Step-by-step explanation:

First Let's us find the sum.

[tex]\sf\longmapsto \: 3x²y - 5a + 4b + (-9x²y - 7b + 4a)[/tex]

[tex]\sf\longmapsto3x²y - 9x²y - 5a + 4a + 4b - 7b [/tex]

[tex]\sf\longmapsto \: -6x²y - a - 3b[/tex]

Now, let's us find the difference (minus)

[tex]\sf\longmapsto \: 3x²y - 5a + 4b - (-9x²y - 7b + 4a)[/tex]

[tex]\sf\longmapsto3x²y + 9x²y - 5a - 4a + 4b + 7b[/tex]

[tex]\sf\longmapsto \: 12x²y - 9a + 11b[/tex]

Now minus the sum from the difference.

[tex]\sf\longmapsto \: 12x²y - 9a + 11b - (-6x²y - a - 3b)[/tex]

[tex]\sf\longmapsto \: 12x²y + 6x²y - 9a + a +11b + 3b[/tex]

[tex]\sf\longmapsto \: 18x²y - 8a + 14b[/tex]

Therefore,[tex]\sf\longmapsto \: 18x²y - 8a + 14b[/tex] is the answer.

Answer:

$1,875

Step-by-step explanation:

Interest = Principal x Rate x Time

Principal = amount of money borrowed

I = $300

r = 16% or .16

t = 1 (year)

300 = .16P

300/.16 = P

P = $1,875

Answer:32mm

Step-by-step explanation:

area of triangle = 1/2 *base * height

192 =6b

base=192/6

base= 32mm

Answer:

y = -2x + 6

Step-by-step explanation:

Slope intercept form: y = mx +b

y + 4 = -2(x - 5)

y + 4 = -2x  + 10

y = -2x + 10 - 4

y = -2x + 6

B) Graph of an Absolute Value Function

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input correspond with exactly one output.    

The given table in Option A) is not a function because there are two corresponding y-values for x = 3.

Option C is also not a function because the input value of x = -1 has two output (y-values): -11 and 5.

Option D is also not a function because the input value of 3 has two output values: -5 and 0.

Option B represents a function because each input value has exactly one corresponding output value.  A useful technique to use in determining whether a given graph represents a function is the Vertical Line Test.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

Attached is an edited screenshot of Option B, where it shows that each blue vertical line has its own corresponding point.  This means that the each line crosses the graph at most once. Therefore, the correct answer is Option B.

The graph

Answer:

4 students to deliver magazines and 6 students to deliver newspaper

Step-by-step explanation:

The minimum number of students needed is 6.

Given that, in one day students can deliver 850 newspapers and 1440 magazines. Each student can deliver either 25 newspapers or 60 magazines in 1 hour.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, in 1 hour a student can deliver 25 newspapers, so in 6 hours a student can deliver 25 × 6 =150

So, number of students = 850/150 = 5.66

≈ 6

Now, 60 × 6 =360

So, number of students = 1440/360 = 4

Therefore, the minimum number of students needed is 6.

Answer:

Step-by-step explanation:

6x - 5 + 3x - 4 = 180     {Supplementary angles}

6x + 3x - 5 - 4 = 180

Combine like terms

9x - 9 = 180

Add 9 to both sides

9x = 180 + 9

9x = 189

Divide both sides by 9

 x = 189/9

x = 21

Answer:

Understand unit rate. The unit rate is a special type of ratio in which the two separate measurements are compared and expressed as a quantity of one.

Look at the data. The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term.

Rewrite the data as a division problem.
