What is the slope of the line passing through the points (−1, 7) and (4, −1)?
2nd picture is the choices I have.
Answers
m = y₂-y₁/x₂-x₁
We are given the following points :
(-1, 7) & (4, -1)
Simply plug everything in :)
m = y₂ - y₁ / x₂ - x₁
Plug in :)
m = -1 - 7 / 4 + 1
Simplify.
m = -8 / 5
So, the slope is -8/5
The first answer choice is correct.

which of the following shows a strategy to use to find 4x275 (4x300)+(4x25)
(4x300)-(4x25) (4x275)-100 (4x200)+75
Answers
The correct strategy is (4x275) - 100. So option (3) is correct.
To find 4 multiplied by 275 using the given strategies, let's go through each one:
1. (4x300) + (4x25):
First, calculate (4x300) = 1200. Then, calculate (4x25) = 100. Finally, add these results together: 1200 + 100 = 1300.
2. (4x300) - (4x25):
Calculate (4x300) = 1200. Then, calculate (4x25) = 100. Now, subtract the second result from the first: 1200 - 100 = 1100.
3. (4x275) - 100:
Simply multiply 4 by 275 to get 1100. Then, subtract 100: 1100 - 100 = 1000.
4. (4x200) + 75:
Calculate (4x200) = 800. Then, add 75: 800 + 75 = 875.
The correct strategy is the third one: (4x275) - 100.
Detailed Calculation:
1. [tex]\(4 \times 275 = 1100\)[/tex]
2. [tex]\(1100 - 100 = 1000\)[/tex]
So, using the strategy of (4x275) - 100, the result is 1000.

The sum of the square of two consecutive whole number is 25. Find the numbers
Answers
The sum of the squares of two consecutive whole numbers is 25. Find the numbers. Let the first be represented by x and the second by x+1.
Then x^2+(x+1)^2=25. Expanding, x^2+x^2+2x+1=25.
Rewriting this as a quadratic equation in standard form,
2x^2+2x+1=25, or 2x^2+2x-24=0. Simplifying, x^2+x-12=0.
Factoring, (x-3)(x+4)=0. Solving for x: x-3=0, so x=3; x+4=0, so x=-4.
Choose the positive x value: x=3. Then the next consecutive number is 2+1=3+1=4.
Check: Does 3^2 + 4^2 = 5^2 = 25? Yes.
The numbers are 3 and 4.

Evaluate 4x-3 when x=_3
Answers
To evaluate the expression 4x-3 for x = -3, we substitute -3 into the expression and follow the order of operations, resulting in a value of -15.
Explanation:To evaluate the expression 4x-3 when x is -3, we simply substitute -3 in place of x and calculate the result as follows:
Replace x with -3: 4(-3) - 3.Multiply 4 by -3: -12 - 3.Finally, subtract 3 from -12 to get: -15.Therefore, evaluating 4x-3 when x is -3 gives us -15.
clay is reading a map to decide his vacation route. The map has a scale of 1cm equals 18miles. If he estimates the length of his vacation route on a map is 14 centimeters what is the length in miles
Answers
If a distance on the map is 14 cm, it is 14 times larger than 1 cm.
That means the real distance is 14 times larger than 18 miles.
What is 14 * 18 miles?
Using the map scale of 1cm equals 18 miles, the actual length of Clay's vacation route is calculated as 252 miles by multiplying 14 centimeters (the length on the map) by 18 miles (the scale conversion factor).
Clay is using a map scale to plan his vacation route. The scale of the map is given as 1cm equals 18 miles. To calculate the actual length of Clay's vacation route in miles, we can set up a simple proportion. Since 1cm on the map represents 18 miles in reality, we multiply the length on the map, which is 14 centimeters, by 18 to find out how many miles this length represents:
Length in miles = 14 cm * 18 miles/cm
After performing the multiplication, we get:
Length in miles = 252 miles
Therefore, Clay’s vacation route is 252 miles long according to the map's scale.

3. Find the scale factor using the given scale drawings and measurement below
Answers
The question asks to find the scale factor for given scale drawings and measurements. A scale factor is computed by creating a ratio comparing the measurement of the scale drawing to the actual measurement, simplifying that ratio to find the scale factor.
Explanation:The subject of the question is concerned with finding the scale factor from a given scale drawing and measurements. In mathematics, particularly in geometry, a scale factor is used to transform the size of a figure without altering its shape.
Step-by-Step ExplanationTo find the scale factor for each given scale drawing, you will need to create a ratio or a fraction that compares the scale measurement to the actual measurement. Here’s how you might solve one of the problems:
Example: What is the scale factor if 3 inches is equal to 12 feet?
Solution:
Convert all measurements to the same unit, for instance, turn feet into inches (1 foot = 12 inches).Write the ratio of the scale drawing to the actual measurement.Reduce the ratio to its simplest form to find the scale factor.rewrite 8/9 with a denominator of 63
Answers
So you need to multiply 9 by 7 to get 63.
But since it's a fraction, you can't multiply the denominator without multiply the numerator. So you need to multiply the denominator, 9, by 7 and the numerator, 8, by 7.
8/9 = (8*7) / (9*7) = 56/63
So 8/9 = 56/63
Hope this helps! :)
Final answer:
To rewrite the fraction 8/9 with a denominator of 63, multiply both the numerator and denominator by 7 to get 56/63.
Explanation:
To rewrite 8/9 with a denominator of 63, you need to find a number that you can multiply both the numerator (8) and the denominator (9) of the original fraction by, so that the denominator becomes 63. To do this, divide 63 by the original denominator, 9, which gives you 7. Thus, the number you need to multiply by is 7.
Multiply both the numerator and the denominator by 7:
Numerator: 8 times 7 = 56
Denominator: 9 times 7 = 63
Therefore, the fraction 8/9 with a denominator of 63 is 56/63.

Also important to keep in mind: when we say we want to "factor" an expression with more than one term added together, what we really want to do is reverse the distributive property. In case you've forgotten, the distributive property is a property of multiplication that states that if you have three numbers a, b, and c, a(b+c) = ab + ac. You distribute the a to each of the terms in the parentheses. Here, you're given the ab + ac part, and you have to work your way back. To give an example, if we had the expression:
[tex]24x+36[/tex]
We can use the fact that 12 is the greatest common factor of 24x and 36 to rewrite it:
[tex]12(2x)+12(3)[/tex]
And, realizing that 12 has been distributed to the 2x and the 3, reverse the distributive property to get:
[tex]12(2x)+12(3)=12(2x+3)[/tex]

If a project is handed in late you receive 8/9 of your earned points. You received 72 points on your late project. How many points did you lose
Answers
In this situation, because the project was handed in late, you lost a total of 9 points. The full score was 81, and you got 72 after a deduction.
Explanation:The principal in this problem is understanding proportion. Given that handing in a project late results in receiving 8/9, or approximately 88.88%, of the total points, we'll figure out the total possible score by dividing the received points (72) by the portion of the full score you got for handing in the project late, which is 8/9. So, 72 ÷ 8/9 = 81. This would be the original points you could have received. You can then subtract the received points (72) from the original points (81) to ascertain the number of points lost. Therefore, 81 - 72 = 9. Consequently, you lost 9 points because the project was handed in late.

The value V of a square glass varies directly as the square of its length X cm. If the value of a square glass with length 3 cm is $243, find the value of a glass with length 5 cm
Answers
Then, the variation equation is given by
[tex]V\propto X^2 \\ \\ \Rightarrow V=kX^2[/tex]
Given that value of a square glass with length 3 cm is $243, we have:
[tex]243=k(3)^2=9k \\ \\ \Rightarrow k= \frac{243}{9} =27 \\ \\ \Rightarrow V=27X^2[/tex]
Thus, the value of a glass with length 5 cm is
[tex]V=27(5)^2=27\times25=\bold{\$675} [/tex]
The value V of a square glass varies directly as the square of its length X cm. This means that V is proportional to [tex]X^2[/tex], which can be expressed as:
[tex]\[ V = kX^2 \][/tex]
where k is the constant of proportionality.
Given that the value of a square glass with length 3 cm is $243, we can use this information to find the constant k:
[tex]\[ 243 = k(3)^2 \][/tex]
[tex]\[ 243 = 9k \][/tex]
[tex]\[ k = \frac{243}{9} \][/tex]
[tex]\[ k = 27 \][/tex]
Now that we have the value of k, we can find the value of a glass with length 5 cm by substituting X = 5 into the original equation:
[tex]\[ V = 27(5)^2 \][/tex]
[tex]\[ V = 27 \times 25 \][/tex]
[tex]\[ V = 675 \][/tex]
Therefore, the value of a glass with length 5 cm is $675.
The answer is: 675.
