Answer:

Step-by-step explanation:

The following angles are equivalent:

  Q = U = 45°

  R = T = W = 225°

  S = V = 90°

  X = 135°

Reflection, any rigid transformation, or any uniform dilation will not change the measures of the angles. That is, U = U', for example.

So, the true angle statements are ...

Answer: y = 1.73*x - 0.46

Step-by-step explanation:

For a linear equation of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we have an angle of A degrees with respect to the x-axis, the slope of the function can be calculated as:

Tan(A) = a.

in this case, we have we have an inclination of 30° to the positive x-axis (measured from the positive y-axis) and we know that the angle between the positive x-axis and the positive y-axis is 90°, then the angle measured from the positive axis will be such that:

A + 30° = 90

A = 90° - 30° = 60°

Then the slope is:

a = Tan(60°) = 1.73

Then we have the equation:

y = 1.73*x + b

And we know that this line passes through the point (2, 3) then we can replace x by 2 and y by 3 in the equation, and find the value of b.

3 = 1.73*2 + b

3 - 1.73*2 = b = -0.46

Then the equation is:

y = 1.73*x - 0.46

Answer:

4/3

Step-by-step explanation:

Let the fractions be A and B.

Given the following data;

Fraction A = 8/9

Fraction B = 2/3

[tex] \frac {Fraction A}{Fraction B} = \frac {\frac {8}{9}} {\frac {2}{3}} [/tex]

[tex] \frac {Fraction A}{Fraction B} = \frac {8}{9} * \frac {3}{2} [/tex]

[tex] \frac {Fraction A}{Fraction B} = \frac {24}{18} [/tex]

Dividing by 6, we have;

[tex] \frac {Fraction A}{Fraction B} = 4/3 [/tex]

Denote x2 by y.

(x2-3)7=(y-3)7

This is a binomial expansion in y, and you want the coefficient of y4 because y4=x8

You have 7 terms of (y-3) in (y-3)7.  To get the fourth power of y, you need to choose y from four of the terms.  The number of ways you can do this is the combinations of 7 things taken 4 at a time.  This is:

7!/(4!3!)=35

So, the coefficient of x8 in the given expansion will be 210.

Answer:

I think the answer is 20....I'm so sorry if that is wrong :[

The given expression at {x} = - 2 and {y} = -4 evaluates to 20.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the expression -

3x² - 2y

The given equation is -

3x² - 2y

For {x} = - 2 and {y} = -4, we can evaluate the expression as -

3(-2)² - 2(-4)

3 x - 2 x - 2 - 2 x - 4

3 x 4 + 8

20

Therefore, the given expression at {x} = - 2 and {y} = -4 evaluates to 20.

===================================================

Explanation:

The combination of angle x and the 93 degree angle forms x+93. This obtuse angle is congruent to 130 because these two angles are alternate interior angles and because line L is parallel to line M.

So,

x+93 = 130

x+93-93 = 130-93 .... subtracting 93 from both sides

x = 37
