Hi there!

[tex]\large\boxed{UV = 13}[/tex]

Since U and V are midpoints of the legs, then UV is the average of both WX and ZY.

Therefore:

(ZY + WX)/2 = UV

Substitute in the given expressions:

[(6x + 5) + (x + 7)]/2 = 8x - 3

Simplify by combining like terms:

(7x + 12)/2 = 8x - 3

Multiply both sides by 2:

7x + 12 = 16x - 6

Subtract 7x from both sides and add 6 to both sides:

18 = 9x

Divide both sides by 9:

18/9 = x

x = 2.

Plug in this value of x into the equation for UV:

8(2) - 3 = 16 - 3 = 13.

3x -18 + 4x + 12 -6x = x - 6

The answer is x-6.Remove the Parentheses and distribute 3 through the Parentheses and put the + between Parentheses.Collect terms you will get x-18+12 and calculate the sum you will get the answer x-6.

The length of x in the right triangle is 31.9 units.

How to solve the side of a right triangle?

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the side of a right triangle can be found using trigonometric ratios as follows:

Hence,

cos 15° = adjacent / hypotenuse

adjacent side = x

hypotenuse side = 33 units

cos 15° = x / 33

cross multiply

x = 33 cos 15°

x = 33 × 0.96592582628

x = 31.8755522675

Therefore,

x = 31.9 units

A company found that the average customer rating of

A) For every increase of 44 in the average customer rating,

B) For every increase of 1 in the average customer rating,
the estimated increase in income is $544.
C) For every increase of 1 in the average customer rating,
the estimated increase in income is $500.
D) For every increase of 1 in the average customer rating,
the estimated increase in income is $44.

Answers

The option that best describes the slope of the graph of the equation in the xy-plane is: D) For every increase of 1 in the average customer rating, the estimated increase in income is $44.

The equation y = 44x + 500 represents the relationship between the average customer rating (x) and the estimated income (y) of a certain product. The coefficient of x, which is 44, determines the slope of the graph. In this case, it means that for every increase of 1 in the average customer rating, the estimated increase in income is $44. Therefore, option D is the correct answer. Option A is incorrect because it suggests a fixed increase of $500 for every increase of 44 in the rating, which is not accurate. Option B is also incorrect as it implies a higher increase in income than what the equation represents. Option C is incorrect because it overestimates the increase in income without considering the coefficient of x.
