Answer:
The number is 97Step-by-step explanation:
Note: The difference should read 18 not 28, it must be a typo. In general such difference must be a multiple of 9.
Let the digits are x and y.
If the first digit is x and the second digit is y, then the number is 10x + y.
According to the question we have:
x + y = 1610x + y - 18 = 10y + x ⇒ 9x - 9y = 18 ⇒ x - y = 2Add up the equations:
x + y + x - y = 16 + 22x = 18x = 9Find y:
9 + y = 16y = 7The number is 97.

tyrell walks 12 miles in 3 hours. which graph has the slope that best represents his rate
The graph that has the slope that best represents the unit rate of 4 miles per hour is: graph B.
How to Find the Slope of a Proportional Relationship Graph?For any proportional relationship, we can find the slope of the graph by using any point on the line of the graph. The slope of the graph is also the unit rate, Therefore, picking a point on the line, (x, y), we have:
Slope (m) = y/x.
Number of miles Tyrell walks (y) = 12 miles
Time spent working (x) = 3 hours
The unit rate or slope = y/x = 12/3
Slope/unit rate (m) = 4 miles per hour.
From the graphs given, only graph B has the same unit rate/slope as 4, when we use the point, (5, 20).
Slope of graph B = 20/5 = 4.
Therefore, the graph that has the slope that best represents the unit rate of 4 miles per hour is: graph B.

Fill in the inequalities below to specify the graph's range shown.
Range: __ is not greater than or equal to y, which is below 5.
The domain and range is the graph's domain is its set of potential input values, and its range is its set of potential output values.
Following is the finished inequality reflecting the set of the domain and range;
First,
Domain: -4 is below x, which is below or equal to 4.
Second,
Range: -2 is below y, which is below or equal to 5
The attached graph shows that the point (-4, 5) has an open circle, which denotes that the point has no value.
The closed circle at the other end of the graph, at the coordinates (4, -2), denotes that the graph has a value at that location (4, -2)
First,
The domain of a graph is the set of potential inputs (x-values) for the graph, expressed as inequality is -4 < x ≤ 4
Therefore;
To complete the inequality for the domain, gives;

Consider the line y=6×-7
what is the slope of a line parallel to this line?
what is the slope of a line perpendicular to this line?
Answer:
The slope of a line parallel to this line will be: 6
The slope of the perpendicular line will be: -1/6
Step-by-step explanation:
We know the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope b is the y-interceptGiven the equation
[tex]y=6x-7[/tex]
Thus, the slope of the line is: 6
The slope of a line parallel to the line:
We have already determined that the slope of the line is: 6
We know that the parallel lines have the same slope.Thus, the slope of a line parallel to this line will be: 6
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: 6
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be:
[tex]\frac{-1}{6}\:\:[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{1}{6}[/tex]

A bouncing toy reaches a height of 64 inches at its first peak, 48 inches at its second peak, and 36 inches at its third peak. Which explicit function represents the geometric sequence of the heights of the toy?
f(x) = 48(Five-sixths) Superscript x minus 1
f(x) = 48(three-fourths) Superscript x minus 1
f(x) = 64(three-fourths) Superscript x minus 1
f(x) = 64(Five-sixths) Superscript x minus 1
Answer:
The correct option is;
f(x) = 64(three-fourths)Superscript x minus 1
Step-by-step explanation:
The first peak height that the bouncing toy reaches = 64 inches
The second peak height that the bouncing toy reaches = 48 inches
The third peak height that the bouncing toy reaches = 36 inches
Therefore, given that the sequence has a common ratio, r = 48/64 = 36/48 = 3/4
The first term of the sequence, a = The first peak height reached = 64
The xth term of the geometric sequence with general form, xth term = ar⁽ˣ⁻¹⁾
The xth term of the geometric sequence, f(x), is therefore, given as follows;
[tex]f(x) = 64 \times \left(\dfrac{3}{4} \right) ^{(x - 1)}[/tex]
The correct option is;
f(x) = 64(three-fourths)Superscript x minus 1
Step-by-step explanation:
The first peak height that the bouncing toy reaches = 64 inches
The second peak height that the bouncing toy reaches = 48 inches
The third peak height that the bouncing toy reaches = 36 inches
Therefore, given that the sequence has a common ratio, r = 48/64 = 36/48 = 3/4
The first term of the sequence, a = The first peak height reached = 64
The xth term of the geometric sequence with general form, xth term = ar⁽ˣ⁻¹⁾
The xth term of the geometric sequence, f(x), is therefore the correct answer is C

Olympus Mons's peak rises 25 km above the surface of the planet Mars. The diameter of Mars is approximately 6794 km. What is the distance from the peak of Olympus Mons to the horizon to the nearest kilometer?
Answer:
1.17*10^14 km
Step-by-step explanation:
kindly find attached the image for your reference
Step one:
The diameter of Mars is approximately 6794 km
hence the radius is = 6794/2= 3397km
Step two:
Use the Pythagorean Theorem
[tex]x^2 + 3397^2 = (3397 + 25)^2\\\\[/tex]
[tex]x^2 + 11539609 = (11710084)^2\\\\x^2 + 11539609 = (11710084)^2\\\\x^2= (11710084)^2-11539609 \\\\x^2= 1.37*10^14-11539609 \\\\x^2=1.37*10^14\\\\x= √1.37*10^14\\\\x=1.17*10^14 km[/tex]
