plot -2 1/2 and 1 3/4 on a number line
To plot -2 1/2 and 1 3/4 on a number line, draw a line with zero at middle. Move 2.5 units to the left from zero for -2 1/2 and place a dot. Then, move 1.75 units to the right from zero for 1 3/4 and place a dot.
Explanation:To plot the numbers -2 1/2 and 1 3/4 on a number line, you first need to understand that these are mixed numbers. -2 1/2 means "two and a half units to the left of zero", whereas 1 3/4 means "one and three quarters units to the right of zero".
Step 1: Draw a number line with zero in the middle. Include distance markers each representing 1 unit. For the purpose of this exercise, let's say negative numbers are on the left and positive numbers are on the right.
Step 2: To plot -2 1/2, start at 0 and move 2.5 units to the left (-2 for the whole number and -0.5 for the fractional part). Place a point here.
Step 3: To plot 1 3/4, start at 0 and move 1.75 units to the right (+1 for the whole number and +0.75 for the fractional part). Place a point here.
This is how you plot the numbers -2 1/2 and 1 3/4 on a number line.

What is the slope-intercept form of the linear equation 2x–8y=32 ?
What is the equation of this graphed line?
Enter your answer in slope-intercept form in the box. (Graph is on picture)
Which equation shows y=3/4x-5/2 in standard form?
A. 3x−4y=10
B. 3x−4y=−10
C. 4x−3y=10
D. 4x−3y=−10
1. The slope-intercept form of the linear equation [tex]\(2x - 8y = 32\)[/tex] is [tex]\(y = \frac{1}{4}x - 4\).[/tex]
2. The equation of the graphed line is [tex]\(y = -\frac{9}{8}x + 7\).[/tex]
3. The standard form of [tex]\(y = \frac{3}{4}x - \frac{5}{2}\)[/tex] is option A: [tex]\(3x - 4y = 10\).[/tex]
Let's break down the given information step by step:
1. Slope-Intercept Form of the Linear Equation:
- The given equation is 2x - 8y = 32.
- To express it in slope-intercept form (y = mx + b), we need to solve for y:
2x - 8y = 32
-8y = -2x + 32
[tex]y = \frac{1}{4}x - 4[/tex]
Therefore, the slope-intercept form of the given equation is [tex]\(y = \frac{1}{4}x - 4\)[/tex].
2. Equation of the Graphed Line:
- The graphed line has the equation [tex]\(y = -\frac{9}{8}x + 7\)[/tex].
3. Standard Form of [tex]\(y = \frac{3}{4}x - \frac{5}{2}\)[/tex]:
- We want to express [tex]\(y = \frac{3}{4}x - \frac{5}{2}\)[/tex] in standard form (Ax + By = C).
- Multiply both sides of the equation by 4 to get rid of fractions:
4y = 3x - 10
3x - 4y = 10
Therefore, the standard form of [tex]\(y = \frac{3}{4}x - \frac{5}{2}\) is \(3x - 4y = 10\)[/tex].
Given this information, the correct answer is A. 3x − 4y = 10.

Modeling with systems of linear inequalities
Modeling with systems of linear inequalities involves using multiple linear inequalities to represent constraints and solve problems with multiple variables. We can graph the inequalities on a coordinate plane and find the feasible region, which represents all the solutions that satisfy the constraints.
Explanation:Modeling with systems of linear inequalitiesModeling with systems of linear inequalities is a mathematical concept that involves using multiple linear inequalities to represent constraints in a real-world situation. This allows us to model and solve problems involving multiple variables and constraints, such as optimizing profit or finding feasible solutions.
Here's an example:
Let's say we have two variables, x and y, representing the number of units of two products.We also have two inequalities, 2x + 3y <= 10 and x + y >= 4.These inequalities represent constraints on the production and sales of the products.To model this situation, we graph the two inequalities on a coordinate plane.The feasible region, the area where the shaded regions of both inequalities overlap, represents the set of solutions that satisfy all the constraints.We can then use this model to analyze and solve various problems, such as finding the maximum profit by maximizing a certain objective function within the feasible region.Learn more about Modeling with systems of linear inequalities here:https://brainly.com/question/34246005

Which expression is equivalent to 2x - 17? A) -17 + 2x B) -2x + 17 C) -2x - 17 D) 17 + 2x
The expression (2x - 17) is equivalent to (-17 + 2x). So, option A is the correct answer.
To determine which expression is equivalent to (2x - 17), we can use the distributive property to simplify each option.
A) (-17 + 2x):
This expression is equivalent because of the commutative property of addition. So, (A) is correct.
Here's the detailed calculation:
Given expression: [tex]\(2x - 17\)[/tex]
We'll use the distributive property:
[tex]\(2x - 17 = (2x) + (-17)\)[/tex]
Thus, the expression is already in the form of option A, which is [tex]\(-17 + 2x\)[/tex]. So, option A is the correct answer.
In summary, the expression (2x - 17) is equivalent to option A, (-17 + 2x).

Weight of Fido is:2 kilograms
Weight of Spot is:1 5/8 kilograms which in decimals is: 1.625 kilograms
Weight of Yogi is:3 4/9 kilograms which in decimals is: 3.444 kilograms
Weight of Smart is:4 1/10 kilograms which in decimals is: 4.1 kilograms
Hence, we observe that Smart weight is highest amongst the weight of the other cats.
The sum of 4 consecutive integers is 130
To find the sum of 4 consecutive integers, set up an equation and solve for the unknown numbers. The solution is the four consecutive integers 31, 32, 33, and 34.
Explanation:To find the sum of 4 consecutive integers, we can set up an equation and solve for the unknown numbers. Let's assume the first number is n.
So, the sum can be represented as n + (n+1) + (n+2) + (n+3) = 130.
Combining like terms, we get 4n + 6 = 130. Solving this equation, we find that n = 31. Therefore, the four consecutive integers are 31, 32, 33, and 34.

Which measure is equivalent to 1.5 kg?
A 15 g
B 150 g
C 1500 g
D 15,000 g
The answer would be 1500g.= 1.5 kg.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, given that,
weight= 1.5 kg.
since there are 1000 grams in a kilogram.
For every,
1 kilogram there's 1000 grams
so, if you were to have 1.5 kilograms you'd have
1,500 grams.
500 is half of 1000 so if you have a 0.5 you'd have 500 grams
which you would then add 500 to 1000 which would result 1500.
Hence, the answer is 1.5 kg= 1500.

which two square roots are used to estimate 47
The two square roots used to estimate the number 47 are 6 and 7, because their squares, 36 and 49 respectively, are the nearest perfect squares to 47.
Explanation:The problem is asking for the two square roots used to estimate the number 47. To solve this, think of two perfect squares that are the closest to 47. Those would be the squares of 6 and 7, because 62 equals 36 and 72 equals 49, which are the closest perfect squares to 47. So, we would use 6 and 7 to estimate the square root of 47.

To graph the equation 2x + 5y = 10, Zeplyn draws a line through the points (5, 0) and (0, 2). What is the slope of the line represented by 2x + 5y = 10?
It's B
just took test
The equation of the line passing through points (5, 0) and (0, 2) is y = -2/5x + 2 and slope is -2/5.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is 2x + 5y = 10.
We have to change this equation to slope intercept form
Isolate the term y from the equation
Subtract 2x from both sides
5y = -2x + 10
Divide both sides by 5
y = -2/5x + 2
the slope will be -2/5
Hence, the equation of the line passing through points (5, 0) and (0, 2) is y = -2/5x + 2 and slope is -2/5.

returned over thesame route driving at an average rate of speed of 40 miles per hour. If his total driving time was 1 hour, what was the total number of miles in
the round trip?
let x = miles
we have x miles/ 60mph plus x miles / 40 mph = 1 hour
x/60 + x/40 = 1
we need to calculate 2x for the round trip
calculate common denominator and rewrite the 2 fractions:
2x/120 + 3x/120 = 1
5x= 120
x = 120/5 = 24 miles
24*2 = 48 miles total
check:
1 way would be 48/2 = 24 miles
24/60 = 0.4 hours to drive 24 miles at 60 mph
24/40 = 0.6 hours to drive 24 miles at 40 mph
0.6 +0.4 = 1 hour
