Answer:

(3x - 4) (3x + 4)

Step-by-step explanation:

Area of the square paper = 9x^2 square centimeters

Area of the square corner = 16 square centimeters

The area of the square corner is removed from area of the square paper.

That is,

9x^2 - 16

Factorise by finding the square root of each term

9x^2

Square root of 9x^2 = 3x

Check:

3x * 3x = 9x^2

Square root of 16 = + or - 4

9x^2 - 16 = (3x - 4) (3x + 4)

Check:

(3x - 4) (3x + 4)

9x^2 + 12x - 12x - 16

= 9x^2 - 16

Step-by-step explanation:

given slope m = 4

point (2, -3) for (x1, y1)

equation for point slope form

y - y1 = m(x- x1)

y - (-3) = 4 (x -2)

y + 3 = 4x - 8, simplify

y = 4x - 11

Step-by-step explanation:

Answer: y=1/3x - 22/3

Step-by-step explanation:

If the sum of 5 and x is 20, then the value of x will be 15.

It is given that the sum of 5 and x is 20.

Mathematically, it can be written as:

5 + x = 20

We have to find the value of x.

In order to find the value of x we need to separate the variable and constant.

For this, subtract 5 from both the sides:

5+x-5 = 20-5

5-5 +x = 20-5

Then, solve the operation of subtraction on both the sides of above equation.

0+x = 15   -------(A)

Since, when we add 0 to any quantity, the result will be this quantity itself.

So, 0+x = x -------(B)

From (A) and (B), Sine the left sides of equation (A) and (B) are equal, then the right sides will also be equal.

Equation right sides of (A) and (B). We have:

x = 15

Hence, the value of x is 15.

Answer:

Step-by-step explanation:

A fucntion is basically a machine that follows the instructions it's given and based on those instructions it gives you an answer. So in the function

f(x)=-x+7, our total output (answer) is going to be whatever our "x" is and adding that to 7.

So lets start with -2, plug in -2 for the x variable

f(x)=-(-2)+7, when we solve this we get f(x)=2+7 (negative*negative=positive)

so our final function would be f(x)=9

We can solve the other functions by plugging in the x variable in the same way:  

f(x)=-(-1)+7  this simplifies to f(x)=1+7, so f(x) equals 8

f(x)=-(0)+7   this simplifies to f(x)=0+7, so f(x)=7

f(x)=-(1)+7  this simplifies to f(x)=-1+7, so f(x)=6

f(x)=-(2)+7 this simplifies to f(x)=-2+7, so f(x)=5

Answer:

The answer is 153.8

Step-by-step explanation:

To find the perimeter you sum all the sides. 5.9+12.3+12.3+10.9+12.3+23.2+18.2+10.9+12.3+35.5= 153.8

The value of x in the proportion below is option 1 3 1/2.

When using the butterfly method approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa.

An equation known as proportion shows that the two ratios presented are equal to one another. In other terms, the proportion declares that the two ratios or fractions are equal. In terms of proportion, two sets of supplied numbers are said to be directly proportional if they increase or decrease in the same ratio.

The given proportion is:

[tex]\frac{\frac{1}{2} }{4} = \frac{x}{28}[/tex]

Using the method of cross-product or butterfly method:

[tex]\frac{\frac{1}{2} (28) }{4}=x \\\\\frac{14}{4}=x\\ \\x=3.5[/tex]

The value of x is 3.5. Converting this value into mixed fraction:

3.5 = 3 1/2

Hence, the value of x in the proportion below is option 1 3 1/2.

Answer: 5^3 / 5^-3 = 5^6 = 15,625

Step-by-step explanation:

Ok, you may find useful for problems like this the next two relations:

[tex]x^a*x^b = x^{a + b}[/tex]

[tex]x^a/x^b = x^{a - b}[/tex]

Now we have the equation:

5^3/5^-3

We have a quotient, then we need to use the second relationship, where:

x = 5

a = 3

b = -3

5^3/5^-3 = 5^(3 - (-3)) = 5^(3 + 3) = 5^6 = 15,625

Answer:

All of the above.

Step-by-step explanation:

In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.

Therefore, the unit rate is the same as the rate of change.

And the rate of change is synonymous with the slope.

The constant of proportionality is simply the slope/rate of change for proportional equations.

Therefore, the constant of proportionality is also another word for the unit rate.

Our answer is hence all of the above.

Answer:

The position of the equipment elevator is 315 feet deep.

The position of the elevator of the miners is 208 feet deep.

At that time, the equipment elevator is deeper.

Step-by-step explanation:

Observation: Seems the numbers are doubled. 77 instead of 7; 1313 instead of 13; 2929 instead of 29; and 1616 instead of 16.

Hence, the question is:

A gold mine has two​ elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second. The elevator for the miners descends 13 feet per second. One​ day, the equipment elevator begins to descend. After 29 ​seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 16 ​seconds? At that​ time, which elevator is​ deeper?

Step-by-step explanation:

From the question,

For the equipment elevator

Speed= 7 feet/second

For the elevator of the miners,

Speed= 13 feet/second

To determine the positions of each elevator relative to the surface, we will determine the distance each of the elevator descends.

From the formula

Speed= Distance / Time

Then,

Distance = Speed × Time

From the question,

The equipment elevator begins to descend and after 29 ​seconds, the elevator for the miners begins to descend. To determine the position of each elevator after another 16 ​seconds. That is, the equipment elevator descends for a total of (29+16) seconds and the elevator of the miners descends for 16 seconds.

For the equipment elevator

Speed= 7 feet/second

Time = 29 + 16 seconds = 45 seconds

From,  Distance = Speed × Time

∴ Distance = 7 feet/second × 45 seconds

Distance = 315 feet

Hence, the position of the equipment elevator is 315 feet deep.

For the elevator of the miners

Speed = 13 feet/second

Time = 16 seconds

Distance = Speed × Time

∴ Distance = 13 feet/second × 16 seconds

Distance = 208 feet

Hence, the position of the elevator of the miners is 208 feet deep.

At that time the equipment elevator is deeper.
