The equation 201.50=f+6.50(21) represents the cost of printing the shirts at a second printing company. Find the solution to the equation. The solution is . State what the solution represents in this situation.

Answers

Answer:

f = 65

Setup cost = 65

Step-by-step explanation:

Given the equation : 201.50=f+6.50(21)

Solving for f:

201.50 = f + 136.50

201.50 - 136.50 = f

f = 65

The equation above is written in the form a slope intercept function where,, 6.50 is the gradient and X equals the number of shirts, The total cost of printing is 201.50

f is the intercept and represents the initial fee or setup cost. Hence, the setup. Cost = 65

Joey went to the county fair last weekend. When he got there, he had to walk 1/2 of a mile from the car to the entrance. Then he walked 11/16 of a mile to the carnival rides and 1/2 of a mile from the carnival rides to the farm animal show. Next, he walked 3/4 of a mile back to the car. How many miles did Joey walk in all?​

Answers

Answer:

39/16 or 2 7/16 miles

Step-by-step explanation:

find the common denominator between all fractions (16).

1/2 = 8/16

3/4 = 12/16

8 + 11 + 8 + 12 = 39

Therefore, Joey walked 39/16 or 2 7/16 miles in total

Step-by-step explanation:

use the formula m = y2- y1 / x2 - x1

Answer:

Step-by-step explanation:

The slope of a line can be found using any two points of a line and the slope, m, is defined as

m=(y2-y1)/(x2-x1), we have points (-1,-3) and (0,6) so

m=(6-(-3))/(0-(-1))

m=9/1

m=9

What is the equation of the circle with radius r units, centered at (x,y) ?

If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:

(x-h)^2 + (y-k)^2 = r^2

Given;

The graph of circle

Now,

h=-2

k=-1

(x-h)^2 + (y-k)^2 = r^2

Substituting the values

(x-2)^2 + (y-1)^2 = 12^2

Therefore, the equation of circle will be (x-2)^2 + (y-1)^2 = 12^2.

Step-by-step explanation:

S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.

If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle)  the hypotenuse of the two triangles will be congruent.

Now, as hypotenuse  and  one leg are congruent in both triangles, we can apply RHS congruent
