To solve the inequality 9x ≤ -17, divide both sides by 9 to find x ≤ -17/9, meaning x can be any value less than or equal to approximately -1.888.
The student's question pertains to an inequality in mathematics involving a variable x and requires an understanding of algebraic inequalities. To solve the inequality 9x ≤ -17, we need to isolate the variable x. We can do this by dividing both sides of the inequality by 9, which gives us x ≤ -17/9. It is important to note that dividing by a positive number does not change the direction of the inequality sign.
The value of x must satisfy this inequality, so any number less than or equal to -17/9 is a solution to the inequality. That means x could be -2, -3, or any other value that is less than or equal to approximately -1.888... (since -17/9 is a decimal approximation of -1.888...).

One positive number is 3 times another number. The difference between the two numbers is 62. Find the numbers
Answer:
31
93
Step-by-step explanation:
Let the larger number = y
Let the smaller number = x
y = 3x
y - x = 62
3x - x = 62
2x = 62
2x/2 = 62/2
x = 31
y = 3x
y = 3*31
y = 93
Final answer:
To find two positive numbers where one is 3 times the other and their difference is 62, let one number be x, then solve the equation 3x - x = 62 to find the numbers 31 and 93.
Explanation:
To find the numbers:
Let one number be x, then the other number is 3x.
Form an equation: 3x - x = 62.
Solve for x: 2x = 62, x = 31.
So, the two numbers are 31 and 93.

Answer:
[tex]y = \frac{1}{3} x - 4[/tex]
Step-by-step explanation:
Given equation :-
[tex]y + 2 = \frac{1}{3} (x - 6)[/tex]
• Slope intercept form is
y = mx + c
where , m is slope of the straight line
and c is y intercept of the line !
Solving and simplifying the given equation ,
[tex]3y + 6 = x - 6 \\ \\ 3y = x - 6 - 6 \\ \\ 3y = x - 12[/tex]
[tex]y = \frac{1}{3} x - \frac{12}{3 } \\ \\ y = \frac{1}{3} x - 4[/tex]
So, m = 1/3 and c = ( -4 )
hence , the required slope intercept form of the equation is
[tex]y = \frac{1}{3} x - 4[/tex]
Jordan will hike the trail shown at a rate of 4 mi/h. Write a linear equation to represent the distance Jordan still has to walk after x hours.What does the y-intercept of the equation
represent?
What we know:
Start of trail:
0 miles
End of trail:
25 miles
Answer:
Y=25-4x
Y means the distance Jordan still has to walk after x hours
Step-by-step explanation:
Answer:
y = 25 - 4*x
The y-intercept represents the total distance Jordan has to walk
Step-by-step explanation:
By Definition, speed = distance/time. We are interested in distance, then:
distance = speed*time
Calling x the hours of walking, and knowing that his speed is 4 mi/h, then:
distance = 4*x
The trail length is 25 miles, so if he walked 1 mile, 25 - 1 = 24 miles are left, in general:
y = 25 - 4*x
where y is the distance Jordan still has to walk.
The y-intercept is found replacing with x = 0, then:
y = 25 - 4*0
y = 25
which represents the total distance Jordan has to walk

What is the image point of (-6, -9) after translation left 1 unit and down 5 units?
The original point (-6, -9) is shifted 1 unit to the left and 5 units down to reach the new position (-7, -14).
To find the image point after translating the point (-6, -9) left 1 unit and down 5 units, we subtract the translation values from the coordinates of the original point.
For the horizontal translation (left 1 unit), we subtract 1 from the x-coordinate:
New x-coordinate = -6 - 1 = -7
For the vertical translation (down 5 units), we subtract 5 from the y-coordinate:
New y-coordinate = -9 - 5 = -14
Therefore, the image point after the translation is (-7, -14).
This means that the original point (-6, -9) is shifted 1 unit to the left and 5 units down to reach the new position (-7, -14).
This translation is a geometric operation commonly used in mathematics and computer graphics to move objects or points in a coordinate plane.
Which of the following transformations is shown?
A. Translation 1 unit down
B. Translation 2 units down
C. Translation 3 units to the right
D. Reflection across the line y-axis
Answer:
B. Translation 2 units down
Step-by-step explanation:
Each time you start from a certain y-intercept, its prime gets translated two below each time:
n[1, 0] to n'[-1, 0]
m[4, 0] to m'[2, 0]
Now, it does not look perfectly shifted down for m' and m, but it it is definitely translated.

Norma's credit card has an APR of 16%, calculated on the previous monthly
balance, and a minimum payment of 2%, starting the month after the first
purchase. Her credit card record for the last 7 months is shown in the table
below.
Norma's credit card balance at the end of the 7th month is $1,487.22.
How to solveCalculate the interest for each month.
Interest = (Previous month's balance * APR) / 12
Calculate the new balance for each month.
New balance = Previous month's balance + Purchases + Interest - Payments
Here's the calculation for each month:
Month 1:
Interest: 0 (No interest on the first month)
Balance: $500 + $0 = $500
Month 2:
Interest: ($500 * 0.16) / 12 = $6.67
Balance: $500 + $200 + $6.67 - $10 = $696.67
Month 3:
Interest: ($696.67 * 0.16) / 12 = $9.29
Balance: $696.67 + $300 + $9.29 - $20 = $986.29
Month 4:
Interest: ($986.29 * 0.16) / 12 = $13.15
Balance: $986.29 + $100 + $13.15 - $20 = $1079.44
Month 5:
Interest: ($1079.44 * 0.16) / 12 = $14.39
Balance: $1079.44 + $150 + $14.39 - $10 = $1233.83
Month 6:
Interest: ($1233.83 * 0.16) / 12 = $16.45
Balance: $1233.83 + $0 + $16.45 - $15 = $1235.28
Month 7:
Interest: ($1235.28 * 0.16) / 12 = $16.47
After all the computations, taking into consideration the amount spent and paid earlier,
Norma's credit card balance at the end of the 7th month has amounted to $1,487.22.

What is the slope of (5,3) and (5,-9)
The slope is the change in Y over the change in X.
A point is written as ( X,Y), where the first number is the X and the second number is the Y.
You have:
(5,3) and (5,-9)
The change in Y is -9 - 3 = -12
The change in X is 5-5 = 0
The slope becomes -12/0
Because you have a 0 on the bottom of the fraction the slope is undefined because you cannot divide by 0.
The slope is undefined.
Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select three options. y = –Two-fifthsx – 2 2x + 5y = −10 2x − 5y = −10 y + 4 = –Two-fifths(x – 5) y – 4 = Five-halves(x + 5)
The three linear equations that represent the line perpendicular to the line 5x - 2y = -6 and passing through the point (5, -4) are: y = -2/5x - 2, 2x + 5y = -10, and y + 4 = -2/5 * (x - 5).
Explanation:Firstly, to find a line perpendicular to another line, we need to find the negative reciprocal of the slope of the original line. The equation 5x - 2y = -6 can be rewritten in slope-intercept form (y = mx + b) as y = 2.5x + 3, so its slope is 2.5. The negative reciprocal of 2.5 is -2/5. Therefore, the slope of the line we are looking for is -2/5.
Secondly, a line passes through a given point (5, -4), so we can use the point-slope form of the equation, which is y - y1 = m(x - x1). By substituting the values, we get y - (-4) = -2/5 * (x - 5), which simplifies to y + 4 = -2/5 * (x - 5).
Lastly, to find other representations of the same line, the standard form of a linear equation is Ax + By = C. Converting y + 4 = -2/5 * (x - 5) to standard form gives us 2x + 5y = -10. So, the three equations that represent the line are: y = -2/5x - 2, 2x + 5y = -10, and y + 4 = -2/5 * (x - 5).

What is the surface area of a sphere with a radius of 9 units?
The surface area of a sphere with a radius of 9 units is given by the formula 4 (pi) (r)2, resulting in an area of 324 (pi) square units, or approximately 1017.88 square units when using 3.14159 for (pi).
Calculating the Surface Area of a Sphere
To find the surface area of a sphere, you will need to use the formula: surface area = 4 (pi) (r)2, where r is the radius of the sphere. For a sphere with a radius of 9 units, you would calculate the surface area as follows:
Surface Area = 4 (pi) (92)
Surface Area = 4 (pi) (81)
Surface Area = 324 (pi)
So, the surface area of the sphere is 324 (pi) square units. If you use the approximate value of (pi) = 3.14159, then the surface area would approximately be 1017.88 square units.

How much does 8.20 X 10-3dm3 (1dm3 = 1L) sample of aluminum weigh in grams?
centimeters?
Answer:
8.20 grams ; 8.20 cm³
Step-by-step explanation:
At first convert it to m³ from dm³
we know,
1 dm³ =10⁻³ m³
∴ 8.20 X 10⁻³dm3 = 8.20 X 10⁻³ x 10⁻³ m³
=8.20 X 10⁻⁶ m³
m³ to gram :
1 m³ = 10⁶ grams
∴ 8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶x10⁶) grams
= 8.20 grams
m³ to cm³ :
1m³ = 10⁶ cm³
∴8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶ x 10⁶) cm³
=8.20 cm³
