This isn't quite simplified, so you find a common factor for the numerator (top number) and the denominator (bottom number). You should note the number has to go into both numbers, not just one. The largest common factor would be 2 in this case.
10/2=5
-4/2=-2
Now your simplified answer would be 5/2
The slope of the line will be "[tex]-\frac{5}{2}[/tex]".
The given points are:
[tex](x_1, y_1) = (0,-7)[/tex][tex](x_2, y_2)= (-4,3)[/tex]The slope (m) will be:
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the given values, we get
= [tex]\frac{3-(-7)}{-4-0}[/tex]
= [tex]\frac{3+7}{-4}[/tex]
= [tex]-\frac{10}{4}[/tex]
= [tex]-\frac{5}{2}[/tex]

The possible areas to find the area of the composite figure is; Add the area of the rectangle with the area of the triangle and Multiply the area of the rectangle by 2.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The composite figure is made up of two shapesas; a rectangle and a triangle. To determine the total area of the composite figure, we can use one of the methods:
First Add the area of the rectangle with the area of the triangle:
We can find the area of the rectangle by multiplying its length and width. We can determine the area of the triangle by multiplying its base and height and then dividing by 2.
Once we get both areas, we can add them together to find the total area of the composite figure.
Multiply the area of the rectangle by 2:
Since the composite figure consists of two rectangles, we can determine the area of one rectangle and then multiply it by 2 to get the total area of the composite figure.
Therefore, by area, the answer will be x2 area of the rectangle and sum of the area of the rectangle and triangle.

- If the area of a square is multiplied by nine, the area becomes 16 square inches. Find the
length x of a side of the square,
Answer:
1⅓ inches
Step-by-step explanation:
Area = side² = x²
9(x²) = 16
x² = 16/9
x = 4/3 inches or 1⅓ inches
Final answer:
To find the side length x of the original square when the area multiplied by nine equals 16 square inches, solve the equation [tex]9 \times x^2 = 16[/tex], resulting in x being [tex]\frac{4} {3}[/tex] inches or approximately 1.33 inches.
Explanation:
If the area of a square is multiplied by nine and becomes 16 square inches, we can write the equation as
[tex]9 \times x^2 = 16[/tex], where x is the length of a side of the square.
To find the length of the side x, we first divide both sides of the equation by 9 to isolate [tex]x^2[/tex]:
[tex]x^2 = \frac{16}{9}[/tex]
Then, we take the square root of both sides to solve for x:
x = [tex]\frac{4} {3}[/tex] or approximately 1.33 inches.
So the length x of a side of the original square is [tex]\frac{4} {3}[/tex] inches.

Rectangle wxyz has the following coordinates w(1,1),x(5,1),y(5,4). What’s the missing coordinate for point z?
To find the missing coordinate for point Z of rectangle WXYZ, we apply the properties of rectangles with given coordinates W(1,1), X(5,1), and Y(5,4). Z shares its x-coordinate with W and its y-coordinate with Y, so the missing coordinate for Z is Z(1,4).
Explanation:To determine the missing coordinate for point z of rectangle WXYZ, we need to understand the properties of rectangles. A rectangle has four right angles, and opposite sides are equal and parallel. Coordinate geometry principles are applied here for pinpointing the missing point.
Given the coordinates of points W(1,1), X(5,1), and Y(5,4), we can deduce the coordinates of Z. Since WX is a horizontal line segment and WY is a vertical line segment, we can infer that X and Y have the same x-coordinate because they are both on the right side of the rectangle. Similarly, W and Z should have the same x-coordinate since they are on the left side. Since the x-coordinate of W is 1, so will be the x-coordinate of Z.
Also, because W and X have the same y-coordinate, we know that the top and bottom sides of the rectangle are horizontal. Y and Z, therefore, must have the same y-coordinate, which is 4, the y-coordinate of point Y.
Thus, the missing coordinate for point Z is Z(1,4).
A basketball player makes 70% of his free throws the random numbers below represent 20 trials for a simulation let the numbers 0 to 6 represent a made free throw and let 7 to 9 represent a missed free throw use this simulation to estimate the probability that the player makes both free throws. (5,5) (0,6) (9,6) (7,4) (9,1) (7,3) (0,4) (9,3) (2,9) (1,4) (6,8) (5,3) (1,7) (1,7) (1,8) (3,5) (7,2) (2,1) (0,6) (1,8)
Answer:
Step-by-step explanation:To estimate the probability that the player makes both free throws based on the given simulation results, we can analyze the number of successful free throws (numbers 0 to 6) in each trial. From the provided data, we can identify the trials where both free throws were successful (made), indicated by the numbers 0 to 6 occurring twice in a row. Let's examine the data:(5,5) (0,6) (9,6) (7,4) (9,1) (7,3) (0,4) (9,3) (2,9) (1,4) (6,8) (5,3) (1,7) (1,7) (1,8) (3,5) (7,2) (2,1) (0,6) (1,8)Based on this data, we can see that the combinations where both free throws were made (0 to 6 occurring twice in a row) are:
(5,5) (1,8)Therefore, there are 2 trials out of 20 where the player made both free throws.To estimate the probability, we can divide the number of trials where both free throws were made (2) by the total number of trials (20):Probability = Number of successful trials / Total number of trials
Probability = 2 / 20
Probability = 0.1Therefore, based on this simulation, the estimated probability that the player makes both free throws is 0.1 or 10%.
The probability that the player makes both free throws is 55%.
Given data:
To estimate the probability that the player makes both free throws, count the number of trials where both free throws were made and divide it by the total number of trials.
Looking at the given random numbers, the pairs (5,5), (0,6), (9,6), (7,4), (9,3), (2,9), (1,4), (6,8), (5,3), (3,5), and (7,2) represent made free throws.
On counting the number of trials where both free throws were made, there are 11 pairs.
Since there are 20 total trials, the estimated probability of the player making both free throws is:
11/20 = 0.55
Hence, the estimated probability that the player makes both free throws is 0.55 or 55%.

Farmer Brown and Farmer Green were talking over their fence one afternoon. Farmer Brown said, "If you gave me one of your cows, we would have the same number of cows." Farmer Green said, "If you gave me one of your cows, I would have twice as many cows as you." How many cows do they have in total?
Farmer Brown has 5 cows and farmer Green has 7 cows
Step-by-step explanation:
Let the no. of cows farmer brown has be 'b'
Let the no. of cows farmer green has be 'g'
Given that,
B+1 = G-1
G = B + 2
G+1 = 2(B-1)
G+1 = 2B - 2
G = 2B -3
B + 2 = 2B - 3
2 + 3 = 2B - B
B = 5
G = B +2
G = 5 + 2
G = 7
Farmer Brown has 5 cows and farmer Green has 7 cows
4. The perimeter of a rectangle is 42 yards.
The difference of the length and width of
the rectangle is 7 yards. Find the length
and width.
Answer:
Step-by-step explanation:
Let width = x
Length = 7 + x
Perimeter = 42 yards
2*(length + width) = 42
2* ( 7 + x + x) = 42
7 + 2x = 42/2
7 + 2x = 21
2x = 21 - 7
2x = 14
x = 14/2
x = 7
Width = 7 yards
Length = 7 + 7 = 14 yards

If (-5+z) is positive, but (-6+z) is negative, what is one number that z could be?
The number that satisfies both conditions (-5+z being positive and -6+z being negative) given in the question is z = 6.
Explanation:To solve this problem, we use the clues given in the question that (-5+z) is positive and (-6+z) is negative. A number, when added to -5, resulting in a positive one, must be greater than 5. However, when the same number is added to -6, it results in a negative answer, meaning it must be less than 6.
Considering both conditions and finding a number that meets them, we can see that z = 6 is the only possible option. This is because 6 is greater than 5 making -5+6 positive. However, since 6 is equal to 6, -6+6 equals zero, and zero isn’t considered negative, thus satisfying both conditions.

What is the image of

after a reflection over the y-axis?
Answer:
(6, 9 )
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 6, 9 ) → (6, 9 )
Reflection over the y-axis in mathematics changes the sign of the x-coordinate of a point while the y-coordinate remains unchanged. Therefore, the point (-6,9) reflects over the y-axis to become (6,9).
Explanation:In mathematics, a reflection over the y-axis is a geometrical transformation of a point in a two-dimensional space. When we reflect a point over the y-axis, the x-coordinate of that point changes its sign, while the y-coordinate remains the same.
Given the point (-6,9), after reflection over the y-axis, it will become (6,9). This is because the reflection changes the sign of the x-coordinate, turning -6 into 6, while the y-coordinate remains the same.
