I know the answer is 4. But I do t understand how the answer arrived.

The two consecutive whole numbers that it lies between are 28 and 29.

The consecutive numbers are those number which follow each other continuously in the order from smallest to largest numbers.

Let the two consecutive numbers be x and x + 1

x + x + 1 = 57

Combine like terms;

2x + 1 = 57

Now Subtract 1 from both sides;

2x = 57- 1

2x = 56

Divide both sides by 2

x = 56/2

x = 28

Thus, x + 1 = 28 + 1 = 29

The two consecutive whole numbers that it lies between are 28 and 29.

Answer:

y = x + 3

y = -x + 11

Step-by-step explanation:

When the slopes are parallel they are the same.  When slopes are negative, the slope is the negative reciprocal.

Parallel:  The slope is 1.  This is the coefficient of the x in the equation given.  If you do not see a number before the x like in  y = x + 1, then number is 1.

Use this form:

y =mx + b  Us the slope of 1 to put in for m.  Use 4 for x and  7 for y

7 =(1)4 + b  Solve for b.

7 = 4 + b  Subtract 4 from both sides.

3 = b

The equation for the parallel line is

y = x + 3.

Perpendicular:

y = mx + b This time the slope is -1 Still use 4 for x and 7 for y

7 = (-1)4 + b

7 =-4 + b add 4 to both sides

11 = b

The equation would be y = -x + 11

The number of times Maria drove the car on day 4 is 9 times.

A line graph is a graph that connects different data points on a graph using a straight line. A line graph is made up of a x-axis and a y-axis. In the line graph given, the number of days is on the x-axis and the number of times the car was driven is on the y-axis. A line graph is used to show quantitative data. Line graphs are used to visualise data.

In order to determine the number of times Maria drove the car on day 4, locate where day 4 is on the x-axis. Then trace 4 upward toward a data point. When the data point is located, trace it to the y-axis. When day 4 is traced to the y-axis, the value gotten is 9.

u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

We are given that:

log 4 ^ u - log 8 ^ v = 1

This can also be written in another way using the logarithm properties. We get that:

u log 4 - v log 8 = 1

Subtract v log 8 from both the sides:

u log 4 = 1 + v log 8

v log 8 = u log 4 - 1

v = ( u log 4 - 1 ) / log 8

v = u log (- 4 ) - ( log 8) ⁻¹

Therefore, we get that, u in terms of v will be represented with the logarithm function as v = u log (- 4 ) - ( log 8) ⁻¹

When you subtract two numbers, if you reduce the first number in the subtraction by one, the result is one less. This is true.

It should be noted that in subtraction when you reduce the first number, you will get a value that's lesser by 1.

In this case, if we have 20 - 5 = 15, then 19 - 5 = 14. We can see that 14 and 15 is a difference of 1.

Therefore, when you subtract two numbers, if you reduce the first number in the subtraction by one, the result is one less. This is true.
