The product of three integers is −7. Determine all of the possible values for the three factors. Write each set of three factors in order from least to greatest. Make sure that each set uses unique integers. Listing the sets in a different order doesn't count.
Three possible products whose factors multiply to −7 are
The three possible sets of integers whose product is -7 are:
1. (1, 1, -7) (least to greatest)
2. (-1, 1, 7) (least to greatest)
3. (-1, -1, 7) (least to greatest)
To find the three possible sets of integers whose product is -7, we need to consider all the combinations of three integers whose product results in -7. Keep in mind that each set should use unique integers. Let's explore the options:
1. Set 1: [tex]\(1 \times 1 \times -7 = -7\)[/tex]
2. Set 2: [tex]\((-1) \times 1 \times 7 = -7\)[/tex]
3. Set 3: [tex]\((-1) \times (-1) \times 7 = -7\)[/tex]
The three possible sets of integers whose product is -7 are:
1. (1, 1, -7) (least to greatest)
2. (-1, 1, 7) (least to greatest)
3. (-1, -1, 7) (least to greatest)
Each set consists of unique integers, and the product of all three integers in each set is -7.

I WILL MARK AS BRAINLIEST! Write and equation that represents the points on the table
Step-by-step explanation:
y = ax +b
2 = 0a+ b => b = 2
4 = -2a + b
4 = -2a +2
2a = 2-4
2a = -2
a = -1
so, y = -x + 2
Kelly bought a cup of coffee and drank 5/8
of it.
Write an addition equation to represent how much coffee is remaining.
Answer: x+5/8 = 1 is the equation where x is the remaining coffee.
Step-by-step explanation:
he drank = 5/8
whole coffee = 1
so
let coffee remaining be x
1-5/8 = x
x+5/8 = 1
The required equation, for the remaining cup of coffee, is x = 1+(- 5/8).
To determine the addition equation of coffee remaining in the cup, for the condition Kelly bought a cup of coffee and drank 5/8 it.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the coffee remaining in the cup be x,
Now, according to the question,
1 = x + 5/8
x = 1 - 5/8
For the addition equation,
x = 1 +(-5/8)
Thus, the required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

I WILL MARK BRAINLIEST! What is the surface area and the volume of this Cylinder?
Answer:
Surface Area = 264π
Volume = 576π
Step-by-step explanation:
in the picture
Answer:
SA= 829.38 Inches² which is 829.38/3.14159 = 264π inch³
V = 110.43 inches³. which is 110.43/ 3.14159 = 35.15π inch³
Step-by-step explanation:
To find the surface area of cylinder, we calculate two area of circle 2πr² and one area of rectangle 2πrh first, and then add them 2πr²+2πrh.
SA of a cylinder =2πrh+2πr², where π≈3.14159
Radius given is 12/2 = 6 inches
= 2 x π x 6 x 16 + 16 x π6 x 6 ≈ 829.3804 = 829.38 Inches²
Volume = h*π *r^2
V = 16 x π
= 110.43 inches³.

Perform the indicated operation. Simplify the result in factored form.
Answer:
[tex]\frac{a+1}{(a-2)(a-1)(a-1)}=[/tex]
Step-by-step explanation:
1. Approach
The easiest method to solve this problem is to factor the expression. In order to subtract (or add) two fractions, both fractions have to have common denominators. When the fractions are factored one can easily see the least common denominator. Convert both fractions to the least common denominator by multiplying the numerator (number over the fraction bar) and denominator (number under the fraction bar) by the value such that both fractions have the same denominator. Finally, one can subtract the numerators of the two fractions.
2. Factoring and Least common denominator
[tex]\frac{3}{a^2-3a+2}-\frac{2}{a^2-1}=[/tex]
Factor the expression, rewrite the quadratic polynomials as the product of two linear polynomials,
[tex]\frac{3}{a^2-3a+2}-\frac{2}{a^2-1}=[/tex]
[tex]\frac{3}{(a-2)(a-1)}-\frac{2}{(a-1)(a+1)}=[/tex]
The least common denominator is: ([tex](a-2)(a-1)(a-1)[/tex])
Convert both fractions to the least common denominator, multiply both the numerator and denominator by the same value to do so,
[tex]\frac{3}{(a-2)(a-1)}-\frac{2}{(a-1)(a+1)}=[/tex]
[tex]\frac{3}{(a-2)(a-1)}*\frac{a-1}{a-1}-\frac{2}{(a-1)(a+1)}*\frac{a-2}{a-2}=[/tex]
Simplify,
[tex]\frac{3}{(a-2)(a-1)}*\frac{a-1}{a-1}-\frac{2}{(a-1)(a+1)}*\frac{a-2}{a-2}=[/tex]
[tex]\frac{3(a-1)}{(a-2)(a-1)(a-1)}-\frac{2(a-2)}{(a-1)(a+1)(a-2)}=[/tex]
3. Solving the expression
[tex]\frac{3(a-1)}{(a-2)(a-1)(a-1)}-\frac{2(a-2)}{(a-1)(a+1)(a-2)}=[/tex]
Distribute, multiply every term inside the parenthesis by the term outside of it,
[tex]\frac{3(a-1)}{(a-2)(a-1)(a-1)}-\frac{2(a-2)}{(a-1)(a+1)(a-2)}=[/tex]
[tex]\frac{3a-3}{(a-2)(a-1)(a-1)}-\frac{2a-4}{(a-1)(a+1)(a-2)}=[/tex]
Simplify further,
[tex]\frac{3a-3}{(a-2)(a-1)(a-1)}-\frac{2a-4}{(a-1)(a+1)(a-2)}=[/tex]
[tex]\frac{3a-3-(2a-4)}{(a-2)(a-1)(a-1)}=[/tex]
[tex]\frac{3a-3-2a+4}{(a-2)(a-1)(a-1)}=[/tex]
Combine like terms,

I WILL MARK AS BRAINLIEST! Find the surface area and Volume of the following figures
Step-by-step explanation:
a) is really easy, right ?
the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.
there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1
SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²
the volume is just length×width×height
V = 7×2×1 = 14 in³
b)
a little bit more difficult, but with a little trick just as easy.
the surface area consists of the 2 circle areas and the mantle "coating".
the area of a circle is pi×r².
we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.
the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.
now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.
circumference of a circle is 2×pi×r
so the surface area is 2×circle + (circumference circle)×12
SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =
≈ 534.07 ft²
the volume is one base area (circle) times height
V = pi×5²×12 = 300pi ≈ 942.48 ft³

Answer:
y = 1500x + 20690
Step-by-step explanation:
We already know the slope. The prompt tells us that in 1996 there were 29,690 movie screens. We can write this as the point (6, 29690). We can find the y-intercept by substituting information into the point-slope formula.
[tex]y-y_1=m(x-x_1)\\\\y-29690=1500(x-6)\\\\y-29690=1500x-9000\\\\y=1500x+20690[/tex]
Now we know that number of movie screens in 1990 was 20,690 and that it increased by 1500 each year.

Are the ratios 3:5 and 2:4 equivalent?
yes or no
Answer:
No, they are not.
Step-by-step explanation:
A ratio can be written as a fraction. So 3:5 is the same as 3/5 and 2:4 is the same as 2/4.
3/5 = 2/4
0.6 = 0.5 INCORRECT
As you can see, the both don't equal the same numbers, so they aren't equivalent.

Volunteers at Sam's school use some of the student council's savings for a special project. They buy 8 backpacks for $8 each and fill each backpack with paper and pens that cost $3. By how much did the student council's savings change because of this project?
The savings was changed by
dollars.
Answer:
The savings were changed by $88
Step-by-step explanation:
1 backpack costs 8 dollars and they bought 8 of them, you have to multiply 8 dollars by 8 cause there is 8 backpacks which is 64 , pen and pencils for 1 backpack costs 3 dollars , so you have to multiply 3 by 8 cause there are 8 backpacks which is 24. then you add 64 and 24 which is 88
