A pair of shoes cost 102.23

Arithmetic: Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. The basic operations of math are addition, subtraction, multiplication and division. Also called higher arithmetic, theoretical arithmetic.

Cost of 3 pairs of shoes and a dress = 352.50

Cost of dress = 45.50

Cost of 3 pairs of shoes = Cost of 3 pairs of shoes and a dress - the cost of dress = 352.20 - 45.50

= 306.7

So, the cost of each pair of shoes will be = Cost of 3 pairs of shoes/Number of pairs bought

= 306.7/3

= 102.23

Step-by-step explanation:

Given angles are vertical angles and they have equal measurements.

We can write the following equation to find the value of x based on this information:

8x - 27 = 6x + 7 transfer like terms to the same side of the equation

8x - 6x = 27 + 7 add/subtract

2x = 34 divide both by 2

x = 17

Answer:

The equation is:

y = -3x + 3

The possible measures  for the other two angles will be that the sum of that angle must be 90 degree.

A triangle is considered to be 3-sided polygon in some cases  Each triangle has three sides and three angles, a few of which may be the same. The portion of the plane enclosed by the triangle is said the triangle interior, whereas the leftover portion is the exterior. Since we are  given that  one of the angles of the  given is a right angle, according to one of the rules of the triangle the sum of all the interior angles of a triangle should be 180, for the triangle ABC,

The complementary angle of the angle is 11.7 degrees

Angles are formed when two or more lines intersect. This in other words means that angles is the measure of space between the intersection of rays or lines

The measure of the angle is given as

Angle = 78.3 degrees

Complementary angles add up to 90 degrees

So, we have the other angle to be

Other angle = 90 - 78.3

Evaluate the difference

Other angle = 11.7

Hence, the other angle is 11.7

Answer:

3/4

-2

Step-by-step explanation:

y = mx + b

Start at the y-intercept. It is (0, -2), so b = -2.

You have

y = mx - 2

Now start at (0, -2). We need to go up and right to the next easy-to-read point on the line. Go up 3 (rise). Go right 4 (run).

slope = rise/run = 3/4 = m.

Now you have

y = 3/4 x - 2

Answer:

See below

Step-by-step explanation:

Use two convenient integer coordinates to calcuate m= slope

I'll use   8,4  and  -4, -5      slope m =   (-5-4)/(-4-8)  = -9/-12 = 3/4

from the graph, the y-axis intercept (b )   is -2

slope - intercept form of a line is given by

y= mx + b

y = 3/4 x -2

The horizontal asymptote is y = -2

The horizontal asymptote is an equation of the form y = k, for some constant k, is a straight line parallel to x-axis.

Horizontal asymptotes are found for rational functions of polynomials when x becomes extremely large, or, as x → ∞.

The function given is, f(x) = (-2x²+3x+5)/(x²+1)

Horizontal asymptote is given by,

y = [tex]\lim_{x \to \infty} \frac{-2x^2+3x+5}{x^2+1}[/tex]

   =  [tex]\lim_{x \to \infty} \frac{x^2(-2+\frac{3}{x} +\frac{5}{x^2}) }{x^2(1+\frac{1}{x^2}) }[/tex]
