A woman drives a distance of 40km to work each day and her average speed for the journey is written as x km/h. If she increase her average speed by 5km/h, it takes 2 minutes less time than usual to make the journey. Calculate her normal speed in km/h​

Answer:

a. x+6 = 0

b. y-2 = 0

Step-by-step explanation:

Given point is:

(-6,2)

a. Line perpendicular to x-axis:

A line perpendicular to x-axis means that the line is vertical and parallel to y-axis. Any equation parallel to y-axis has the form

x = k

where k is the x-coordinate of the point from which the line passes.

So the required equation is:

[tex]x = -6\\x+6 = 0[/tex]

b. Line perpendicular to y-axis:

A line perpendicular to y-axis will be a horizontal line parallel to x-axis having the equation of the form

y = b

where b is the y-intercept

Required equation is:

[tex]y = 2\\y-2=0[/tex]

Hence,

a. x+6 = 0

b. y-2 = 0

Answer:

Average growth= 11.20 feet

Step-by-step explanation:

First, we need to calculate the total growth during those 312 years:

Total growth= 3,512 - 18

Total growth= 3,494 feet

Now, the average growth:

Average growth= total growth / number of years

Average growth= 3,494 / 312

Average growth= 11.20 feet

Answer:

The difference between the high and low temperatures is 29°F

Step-by-step explanation:

Subtraction

The high temperature in Denver, Colorado was 25°F on Monday.

The low temperature was -4°F in the same place.

We are required to find the difference between the high and low temperatures.

We need to subtract 25 and -4:

Difference = 25°F - (-4°F)

Note we change the sign of the subtraction multiplying (-1) by (-1);

Difference = 25°F + 4°F

Difference = 29°F

The difference between the high and low temperatures is 29°F

Answer:

6  ( 2 x + 1)

Step-by-step explanation:

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 20 is about 4.472. Thus, the square root of 20 is not an integer, and therefore 20 is not a square number.

The reason why 20 is not a square number is because it's square root is not an integer.

It follows from the task content that we explain why 20 is not a square number.

First, a square number is one whose square root is an integer. Hence, such a number is a perfect square.

On this note, 20 is not a square number because it's square root is not an integer.

Answer:

25 and 30

Step-by-step explanation:

Given the ratio of 2 numbers is 5 : 6 = 5x : 6x ( x is a multiplier ), then

5x + 6x = 55, that is

11x = 55 ( divide both sides by 11 )

x = 5

Thus

5x = 5 × 5 = 25

6x = 6 × 5 = 30

Then the 2 numbers are 25 and 30

Answer:

1/8.

Step-by-step explanation:

Use l'Hopitals rule - we find the derivative of top and bottom of the fraction.

Derivative of the numerator = 0 - 1/2 (16 - x)^-1/2  -1

=  1 / [ 2 * (16 - x)^1/2

Derivative of the denominator =  1

When x approaches 0 this is 1 / (2*4)

= 1/8.

Another way to do this is to multiply top and bottom by  4 + (16 - x)^1/2

This  becomes   16 - (16 - x) / x(4 + (16-x)^1/2)

= 1 / (4 + (16 + x)^1/2

When x ---> 0

this = 1 /(4 + 4)

= 1/8.

y= (-1/2)x+(5/2)

Step-by-step explanation:

equation point slope

(y-y1)=m(x-x1)

y-3 = -1/2(x+1) add -3 to both sides and distribute

y=( -x/2) +(-1/2)+3 rewrite 3 as 6/2

y=(-1/2)x +(-1+6/2) solve

y= (-1/2)x+(5/2)
