Answer: y = 1/4x +1

Step-by-step explanation:

First, we can find the midpoint of the line segment using the average of x and y coordinates of the endpoints:

M(x,y) = ((-2 + (-6))/2 , (-9 + 7)/2)

M(x,y) = (-4, -1)

To find the slope of the perpendicular bisector, we have to take the negative reciprocal of the slope of the line segment which is (y2-y1)/(x2-x1) = (7-(-9))/(-6-(-2)) = -16/4 = -4

Slope of the perpendicular bisector = -1/slope of the line segment = -1/(-4) = 1/4

Now we can use the point-slope form to find the equation of the line:

y - y1 = m(x - x1)

y - (-1) = 1/4(x + 4)

y = 1/4x +1

so the equation of the perpendicular bisector of the line segment whose endpoints are (-2,-9) and (-6,7) is y = 1/4x +1

Answer: 22.5

Step-by-step explanation: To get a percentage of a number you multiply the number you want the percentage of (125), and multiply it by your percent in decimal form. So basically the equation went like this: 125 x 0.18 = 22.5. Another example of this would be if you wanted to find 60 percent of 20. You would just take 60 and put it in decimal form and multiply. 20 x 0.60 = 12. Hope this helps!

Answer:

840 quarts could be made in 12 hours. The rate per day is 1680 quarts could be made per day.

Step-by-step explanation:

140/2=x/12

reduce/simplify 140/2 to 70

so 70/1=x/12.

cross product

70*12=1*x

840=x

One day has 24 hours,

so we multiply 2 by 12 to get 24,

thus 840*2=1680.

Answer: The relation between the time it will take Rashid to make the trip, t, and the speed at which he slows down, v, can be determined by using the formula:

distance = speed * time

We know that Rashid travels 240 km from Abu Dhabi to Sharjah and that he originally drove at 120 km/h for 2 hours. So, we can write the equation:

240 = 120 * 2

Now, if Rashid slows down by v km/h, then the new speed is (120 - v) km/h and the new time, t, can be determined by substituting the new speed and distance into the equation:

240 = (120 - v) * t

So the relation shows that t = (240 / (120 - v))

This relation shows that the time, t, it will now take Rashid to make the trip is directly proportional to the speed, v, at which he slows down. As Rashid slows down, the time taken to make the trip will increase, and as he speeds up, the time will decrease.

Using the slope and y - intercept, the linear function that models this problem is y = -33.333x + 68.32

A system of linear equation is a set of at least two linear equations containing the same set of variables. Linear equations use only polynomial coefficients and the operations of addition, subtraction, multiplication and division. The solutions to a linear equation system are the values of the variables which make all the equations true.

To solve this problem, we have to define our variables and set our system of linear equations.

Let;

Using the data given, we can find the slope and y - intercept of a linear function that represents this.

slope (m) = y₂ - y₁ / x₂ - x₁

m = 64.99 - 59.99 / 0.10 - 0.25

m = -33.333

Using the slope in the slope-intercept form of a linear equation

y = mx + c

Taking one point;

59.99 = -33.333(0.25) + c

c = 68.32

The linear equation can be written as;

y = -33.33x + 68.32

Given that segment BD bisects segment AC, the value of x is 5.8 units.

If the corresponding sides and/ or internal angles of two shapes have some  common properties, then it can be said that the shapes are similar. Though similarity does not mean congruency.

Given that segment BD bisects segment AC, the value of x can be determined by comparing the sides of triangles ABD and BCD.

Thus, we have;

x/ 7 = 14/ 17

17x = 7 * 14

Since ​14​ is equivalent to 8x, that number must be 14 ÷ 8. Then ​14 ÷ 8 = x, because of the inverse relationship between multiplication and division.

There are 4 basic mathematical operations which are addition, subtraction, division and multiplication.

Multiplication and division are inverse operations because multiplication undoes division and also division undoes multiplication.

We want to find the quotient of 14 and 8. This is expressed as 14 ÷ 8.

Now, we are told to consider that some number times 8 equals ​14. Let the number be x and as such we have;

8x = 14

Now, since 14 is equal to 8x, then that number must be gotten by using the inverse relationship by multiplying both sides by 1/8 to get;

The measure of the alternate exterior angle made by the intersection of road B and road C is 77 degrees.

The pair of angles known as alternate exterior angles are those that are formed on the opposite side of the transversal from the parallel lines' outer side.

According to the alternate exterior angle theorem, alternate exterior angles are regarded as congruent angles or angles of equal measure when two parallel lines are intersected by a transversal.

In this case, two roads, A and B, run parallel to each other. A third road, C, passes through both A and B. Road C creates an exterior angle of 77 with road A. Therefore, the angle will also be equal to 77°.

Graph of g(x) = (1/2)ˣ i.e. Graph of f(x) = 2x reflected over the y-axis is drawn below.

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math.

f = {(a, b)| for all a ∈ A, b ∈ B}.

Given, the function

f(x) = (2)ˣ

g(x) = (1/2)ˣ

g(x) is the graph of f(x) reflected over y- axis.

The rule of reflection over y-axis:

(x, y) → (-x, y)

Thus, when a graph gets reflected over y-axis it means that horizontal components are additive inverse of the original horizontal components.

Therefore the graph of g(x) = (1/2)ˣ is as follows.

let us assume that  f and g are inverse functions, then the condition for  f(x) = y if and only if g(y) = x

What is the system of equations?

A system of equations is a set of two or more equations that are solved simultaneously. Each equation in the system contains one or more variables, and the goal is to find the values of the variables that satisfy all the equations in the system.

y = -1/6x + 7

y = 2x - 6

To graph the equations y = -1/6x + 7 and y = 2x - 6, we can follow these steps:

Plot the y-intercepts of the equations: The y-intercept is the point where the line crosses the y-axis. For the equation y = -1/6x + 7, the y-intercept is (0,7), and for the equation y = 2x - 6, the y-intercept is (0,-6).

Draw the lines: Starting from the y-intercepts, use the slope of the lines to draw the lines. The slope of the first equation is -1/6 and the slope of the second equation is 2.

Find the x-intercept: The x-intercept is the point where the line crosses the x-axis. For the equation y = -1/6x + 7, the x-intercept is (-42,0) and for the equation y = 2x - 6, the x-intercept is (-3,0)

Locate the point of intersection: The point of intersection of the two lines is the solution of the system of equations. The point of intersection for the given equation is (3,1).

What is surface area of square pyramid?

The term "square pyramid" also refers to a polyhedron having a square base and four triangular faces. Where the four faces come together is known as the apex. The pyramid's faces connect the base and the tip. The calculation for the square pyramid's surface area adds the areas of the four triangular faces and the base.

Here the given measures are base = 3.5 cm and height = 7cm.

Now using surface area formula then

Surface area of the square pyramid = Base area + 2bl square unit.

Base area = 3.5 × 3.5 = 12.25[tex]cm^2[/tex]

Remember that the sum of all angles in ANY triangle is 180 degrees. Also, remember that an acute triangle has angles that are all less than 90 degrees. So not only do our options have to add up to 180 degrees, but they also have to be less than 90 degrees in order for the triangle to be acute.

We can immediately exclude options A, B, and C because all three options have angles greater than 90 degrees, which means the triangle isn't acute.

  p:q:r = 12:15:10

Step-by-step explanation:

Given p:q = (2/3):(5/6) and q:r = (3/4):(1/2), you want p:q:r.

We can turn each ratio into a ratio of integers by multiplying by the least common denominator.

  p:q = 4:5 . . . . . . . multiply the given ratio by 6

  q:r = 3:2 . . . . . . . multiply the given ratio by 4

Now, we need to have q be represented in each ratio by the same number. That number will be the least common multiple of its representations in these ratios: LCM(5, 3) = 15.

Multiplying the first ratio by 3, we have ...

  p : q = 12 : 15

Multiplying the second ratio by 5 gives ...

  q : r = 15 : 10

Now, we can write the ratio of interest:

  p : q : r = 12 : 15 : 10
