What is the slope of the line passing through the points (−3, 4) and (2, −1)?
Answers
Answer: -1
Step-by-step explanation:
The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line.
The formula to find the slope is
m = (y2 - y1)/ (x2 - x1)
Where (x1, y1) and (x2, y2) are the two points
The two points given are (-3, 4) and (2, -1)
Substituting it in the formula
m = (-1 - 4)/ (2 - (-3))
By further calculation
m = -5/ (2 + 3)
So we get
m = -5/5
m = -1
Therefore, the slope of the line is -1.

Three different recipes each make a different number of cookies and require a different amount of flour.
Recipe 1: 1 dozen cookies; 1 cup of flour
Recipe 2: 3 dozen cookies; 3.5 cups of flour
Recipe 3: 5 dozen cookies; 6 cups of flour
Determine if the three recipes use a proportional amount of flour.
Yes, it is proportional because the ratios between the number of cookies and cups of flour are all equivalent.
Yes, it is proportional because the cookies increase by 2 dozen for every 2.5 cups of flour.
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
No, it is not proportional because the number of cookies and cups of flour could not be zero at the same time.
Answers
12 cookies in a dozen.
Recipe 1 -> 12:1 -> 12:1 ratio
Recipe 2-> 36:3.5 -> 10.28:1 ratio
Recipe 3-> 60:6 -> 10:1 Ratio
I hope that helps :)
The correct statement is (C) No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that:
Three different recipes each make a different number of cookies and require a different amount of flour.
From the recipe:
The ratios of the number of cookies to the number of cups of flour:
For recipe 1:
= 12/1 = 12
For recipe 2:
= 36/3.5 = 10.28
For recipe 3:
= 60/6 = 10
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
Thus, the correct statement is (C) No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.

Question
Evaluate.
−[−1 1/5÷0.6(1.3)]−5/6
What is the value of the expression?
Enter your answer as a simplified mixed number in the box.
Answers
Answer:
−[−1 1/5 ÷ 0.6(1.3)] − 5/6
First, let's simplify the expression within the square brackets:
−1 1/5 ÷ 0.6(1.3)
To simplify this, let's convert the mixed number to an improper fraction:
−6/5 ÷ 0.6(1.3)
Next, we multiply 0.6 by 1.3:
−6/5 ÷ 0.78
To divide fractions, we can multiply by the reciprocal:
−6/5 * (1/0.78)
Now, let's multiply the numerators and denominators:
-6/5 * 1/0.78 = -6/5 * 1/0.78 = -6/3.9
To simplify this fraction, we can multiply both the numerator and denominator by 10 to eliminate the decimal:
-6/3.9 * 10/10 = -60/39
Now, let's simplify the expression further:
−60/39 − 5/6
To add or subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 39 and 6 is 78:
−60/39 − 5/6 = −(60/39 * 2/2) − 5/6 = −120/78 − 5/6
Now, we can combine the fractions:
−120/78 − 5/6 = (−120 * 6)/(78 * 6) − 5/6 = −720/468 − 5/6
To subtract the fractions, we need a common denominator:
−720/468 − 5/6 = −720/468 − (5 * 78)/(6 * 78) = −720/468 − 390/468
Now, we can combine the fractions:
−720/468 − 390/468 = (−720 − 390)/468 = −1110/468
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 78:
−1110/468 = (−1110 ÷ 78)/(468 ÷ 78) = −15/6
The simplified fraction is −15/6.
However, the question asks for the value as a simplified mixed number. To convert the fraction to a mixed number, we divide the numerator by the denominator:
−15 ÷ 6 = −2 remainder 3
Therefore, the value of the expression is -2 3/6, which can be further simplified as -2 1/2.
So, the value of the expression is -2 1/2.

Because of that, when do you add ± in questions like the ones on top? (take into account units and no units, thanks)
i'm confusion
Also, why do you need (x) in questions like (-7)^3? I feel like there is no point, especially when it is just one problem.
Answers
Answer: It is only +8 because it is an odd power, so you're only multiplying 3 numbers together and not 2 or 4 and so on. Any odd power is always only going to have 1 answer because if you try the other one then it comes out to be the opposite.
You only need the parenthesis if you want to plug it into a calculator because -7 in a calculator is taken as subtracting 7 while (-7) is taken as a negative 7. They are just building good habits early.
