If a region’s average movie theater ticket price in 2007 was $6.51. For 2017, it was estimated to be $8.57, the percent of increase in average movie theater ticket price is 16%

A region's average movie ticket price in 2007 was $6. 51

A region's average movie ticket price in 2017 was $8. 57

Increase in price = 8.57 - 6. 51 = $1.06

Percentage of increase = (increase in price / original price)*100

= (1.06/6.51)*100

16%

Explanation:

A = last year's value = 290,700

B = this year's value = 312,000

C = change in values

C = B - A

C = 312,000 - 290,700 = 21,300

The positive result shows the increase of 21,300 more motorcycles made this year, compared to last year. A negative C value would represent a percent decrease.

Divide this change over the original.

C/A = (21,300)/(290,700) = 0.07327141382869

which is approximate. Let's say we rounded to four decimal places to get 0.0733 which then converts to the percentage 7.33%

Answer:

Any line with a slope of -5/8 would be parallel to this line.

Step-by-step explanation:

First write this in the slope intercept form of a line

y = mx + b.  The number before the x will be the slope.

5x + 8y = 24  Subtract 5x from both sides of the equation

8y = -5x +24 Divide everything by 8

y = -5/8x + 3

No, 12 17 and 14 19 determined ratio are not proportional.

If two ratios depict the same connection, they are said to be proportionate. By writing two ratios as fractions and then reducing them, one may determine if they are proportionate. Your ratios are proportional if the reduced fractions are equal.

We can observe that 17 and 19 are prime numbers,

So, 12 : 17 cannot be simplified further,

Neither 14 : 19 can be simplified.

⇒ 12 : 17 ≠ 14 : 19

The linear function of h is h(x) = -2x -13 and the values of h(3) = -19.

Two point form is a method for finding the equation of a function if two of its points are known. If (x1, y1) and (x2, y2) are the two points then equation of the function is given as-

(y - y1) = {(y1 - y2)/ (x1 - x2)} (x - x1)

Here, we are given that h(7) = -10 and h(-2) = 8

This, means that (7, -10) and (-2, 8) will satisfy the given function

Since, we have two points, we will use the two point form to find the equation of function h.

Substituting, x1 = 7, y1 = -10, x2 = -2 and y2 = 8 in the two point form equation we get-

( y - 7) = {(-10 - 8) / (7 + 2)} (x + 10)

y - 7 = (-18/9) (x + 10)

y - 7 = -2(x + 10)

y - 7 = -2x -20

y = -2x -20 + 7

y = -2x -13

Thus, h(x) = -2x -13

Hence, h(3) = -2(3) -13

= -6 -13

= -19

Therefore, h(3) = -19

The first mistake in solving the given algebraic expression is; Line 3

We are given the algebraic expression as;

6(2y + 6) = 4(9 + 3y)

The first step would be to use distributive property of algebra to expand the bracket to get;

12y + 36 = 36 + 12y

The next step will be to use subtraction property of equality to subtract 36 from both sides to get;

12y = 12y

Now, since the coefficients of the variable is the same on both sides, then it means the equation has no solution and as such the conclusion is that the first mistake is in line 3.

Answer:

y = 6x - 2

Step-by-step explanation:

We will use the slope-intercept form of a line to help us.  We know the slope, we need to determine the y-intercept.  To find this, we need an x and y on the line and the slope.  Fortunately, they have given us all of the information.  An ordered pair is in the form (x,y)  So we will use x = 1 and y = 4 from the point they have given us (1,4)  They have also given us the slope of 6.  We will plug this all into our equation and solve for b  the y-intercept.

y = mx + b

4 = 6(1) + b  

4 = 6 + b  Subtract 6 from both sides of the equation.

-2 = b

Now, write the equation

y = mx + b

y = 6x -2

The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65

A = -6 and B = 65

From the question, we are to express the given expression in the form (x + A)^2+B by completing the square

The given expression is

x² -12x + 101

Using the completing the square method

x² -12x + 101

Divide the coefficient of x by 2 and then square it

The coefficient of x is -12

Dividing by 2, we get

-12/2 = -6

Squaring

(-6)²

Now, add and subtract this value from the expression

x² -12x + (-6)² + 101 - (-6)²

Then, we can write that

(x - 6)² + 101 - (-6)²

(x - 6)² + 101 - 36

(x - 6)² + 65

Thus,

The given expression expressed in the form (x+A)^2+B is (x - 6)² + 65

A = -6

The perimeter of the figure is 8 + √14 units

The coordinates are given as

X(0,1), Y(4, -2), Z(-5, -2)​

Next, we plot the above coordinates on a coordinate plane

See attachment for the plot of the coordinates on a coordinate plane

Next, we calculate the distance between the points using

d = √(x2 - x1)^2 + (y2 - y1)^2

So, we have

XY = √(0 - 4)^2 + (1 + 2)^2 = 5

XZ = √(0 + 5)^2 + (1 + 2)^2 = √14

YZ = √(4 + 5)^2 + (-2 + 2)^2 = 3

The perimeter is calculated as

P = XY + XZ + YZ

So, we have

P = 5 + √14 + 3

Evaluate

P = 8 + √14
