Answer:
Step-by-step explanation:
Use the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
where m = slope
Given the coordinates
(-4, 4) ---> this means x1 = -4 , y1 = 4
(2, -5) ---> this means x2 = 2 , y2 = -5
Substitute these values into the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
[tex]m = \frac{-5 -4}{2 - (-4)} = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}[/tex]
The slope of the line passing through the coordinates (-4, 4) and (2, -5) is - 3/2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The slope of the line passing coordinates (-4, 4) and (2, -5) can be obtained as we know slope is rise over run which is slope(m) = (y₂ - y₁)/(x₂ - x₁) = (-5 - 4)/(2 + 4) = -9/6 = - 3/2.

#SPJ2
six times a number decreased by 8 is less than five times the number plus 21
Answer:
6 ( or any number that isn't a common multiple of 5 and 6 ) you should probably double-check just in case.
Step-by-step explanation:
Question = 6x - 8 < 5x +21
so we know that the product of 6x must be divisible by 6 and 5x must be devisable by 5. so the first factor of 6 is 6 so:
(6 x 6) - 8 < (5 x 6) + 21
36 - 8 < 30 + 21
28 < 51
so x = 6
Honestly, any number would work because 6x is obviously more than 5x, but since for 6x you subtracting 8 and for 5x you adding 21 the answer will always be 6x - 8 < 5x + 21. Unless you use a common multiple of 6 and 5 as your x because then six times that number will always be more than 5 times that number. So for example 30 is a common multiple of 6 and 5 so:
(6 x 30) - 8 is more than (5 x 30) + 21
180 - 8 is more than 150 + 21
172 is more than 171
hope that helps : )
Representing the problem using mathematical equation, the inequality which represents the scenario is n < 29
Let the number be represented as n :
6n - 8 < 5n + 21
We can then solve for n
6n - 5n < 21 + 8
n < 29
Therefore, the inequality expression which represents the possible values of n for which the expression is true is n < 29

Solve for x: 4 − (x + 2) −7
x −9
Answer:
x = 2
Step-by-step explanation:
4 - (x + 2) - 7 = x - 9
4 - x - 2 - 7 = x - 9
-5 = 2x - 9
4 = 2x
x = 2
Please don't report me if I am wrong :(
x=2!
I think you asked: Solve for x: 4 − (x + 2) −7
The answer is x=2
Let's simplify step-by-step.
4−(x+2)−7
=4+−x+−2+−7
Combine Like Terms:
=4+−x+−2+−7
=(−x)+(4+−2+−7)
=−x+−5
That is the simplified answer. If you think carefully, I think x=2
The perimeter of a rectangle is 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation 2⋅length+2⋅width=48. Find the length, in centimeters, if the width is 10 centimeters
Answer:
The length of the rectangle is 14 cm
Step-by-step explanation:
Here, we want to find the length of the rectangle given the width
Mathematically, the perimeter of the rectangle can be calculated using the formula;
2( l + w)
from the question w = 10
and perimeter = 48
Thus;
2( l + 10) = 48
divide both sides by 2
l + 10 = 48/2
l + 10 = 24
l = 24 - 10
l = 14 cm
Can you find the equation of a line parallel to the green
line through the point (-5,-3). Write you equation in
point-slope form.
Answer:
[tex]\displaystyle y+3=-\frac{4}{5}(x+5)[/tex]
Step-by-step explanation:
The point-slope form of the equation of a line is:
y-k=m(x-h)
Where m is the slope and (h,k) is a point through which the line passes.
We are required to find the equation of the line passing through the point (-5,-3) and parallel to the green line shown in the graph.
We need to find the slope of the green line. Once we have the slope, we will have the slope of our line since parallel lines have the same slope.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can clearly identify the following points in the green line: (0,4) (5,0):
[tex]\displaystyle m=\frac{0-4}{5-0}=-\frac{4}{5}[/tex]
Now we have the slope and the point, the equation of the line is:
[tex]\displaystyle y-(-3)=-\frac{4}{5}(x-(-5))[/tex]
[tex]\boxed{\displaystyle y+3=-\frac{4}{5}(x+5)}[/tex]

Find the coterminal angle between 0 and 360°of the angle -280°
Answer: So, the coterminal angle of 450° is -90°.
Step-by-step explanation:(i) 395°
Write 395° in terms of 360°.
395° = 360° + 35°
So, the coterminal angle of 395° is 35◦
(ii) 525°
Write 525° in terms of 360°.
525° = 360° + 165°
So, the coterminal angle of 525° is 165°.
(iii) 1150°
Write 1150° in terms of 360°.
1150° = 3(360°) + 70°
So, the coterminal angle of 1150° is 70°.
(iv) -270°
Write -270° in terms of 360°.
-270° = -360° + 90°
So, the coterminal angle of 270° is 90°.
(v) -450°
Write -450° in terms of 360°.
-450° = -360° - 90°
So, the coterminal angle of 450° is -90°.

A florida factory produces fishing reels at a rate of 800 per day, every day. IN April, they are forced to cut their production by 15due to an aluminum shortage. A chain of sporting goods stores orders 20,000 fishing reels. Will the factory be able to produce enough fishing reels in the 30 days of April to meet this order? Explain how you know.
Answer:
Yes
Step-by-step explanation:
Yes because if you subtract the 15 from 800 you get 785 you times that by 30. You get 23,550. I drop the 30, 1 by 1 and when I got to 26 it is 20,410. so yes they can in 25 and 1/2 days to be exact.

At the supermarket, you can fill your own honey bear container. A customer buys 12 oz of honey for $5.40.
How much does honey cost per ounce?
How much honey can you buy per dollar? Round to the nearest hundredth.
Answer: a. $0.45; b. 2.22 oz
Step-by-step explanation:
From the question, we are informed that acustomer buys 12 oz of honey for $5.40.
a. How much does honey cost per ounce?
To calculate this, we divide $5.40 by 12oz. This will be:
= $5.40/12
= $0.45
b. How much honey can you buy per dollar?
Since 1 ounce cost $0.45, the number of honey that can be bought for $1 will be:
= $1/$0.45
= 2.22 oz

what is the greatest common factor shared by 10 and 40
[tex]\huge\bold\green{Answer:-}[/tex]
Greatest common factor (GCF) of 10 and 40 is 10.
GCF(10,40) = 10
[tex]\huge\bold\red{Explanation:-}[/tex]
We will now calculate the prime factors of 10 and 40, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 40.
Prime Factorization of 10
Prime factors of 10 are 2, 5. Prime factorization of 10 in exponential form is:
10 = 2¹ × 5¹
Prime Factorization of 40
Prime factors of 40 are 2, 5. Prime factorization of 40 in exponential form is:
40 = 2³× 5¹
Factors of 10

Factors of 40
List of positive integer factors of 40 that divides 10 without a remainder.
1, 2, 4, 5, 8, 10, 20
Greatest Common Factor
We found the factors and prime factorization of 10 and 40. The biggest common factor number is the GCF number.
So the greatest common factor 10 and 40 is 10.
The Greatest Common Factor of 10 and 40 is 5.
What is Greatest Common Factor?The greatest common factor is the largest number that is a factor of two or more numbers (GCF). The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both. The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the Highest Common Factor (HCF)
For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
Given:
We have to find the greatest common factor of 10 and 40.
So factorizing each number
10 = 2 x 5
40 = 2 x 2 x 2 x 5
Here the common factor of 10 and 40 is
= 2 x 5
= 10
Thus, the Greatest Common Factor is 10.

When a 49 pound weight is attached to a spring, the spring
stretches 7 inches. Assume that the length of the spring y varies directly
with the weight attached x. Write and solve a direct variation equation to
find the length of the spring when a 63 pound weight is attached.
im not for sure but I think the answer is 9! my reasoning is below,,
Step-by-step explanation:
[tex] \frac{49}{7} = \frac{63}{x} [/tex]
do the crossing method and it would result in this
(49×x) = (63×7)
after simplifying both sides
49x = 441
divide both sides by 49 and the result will be
x = 9 !!
