The gift certificate will pay for the cost of 7 lessons and will have $40 left on it.
Step-by-step explanation:
<span>The given function is f(x) = (7x + 1)/2. Write it as y = (7x)/2 + 1/2. To determine the inverse do these 3 steps. Step 1: Swap x and y to obtain x = (7y)/2 + 1/2. Step2: Solve for y. First, multiply through by 2 to obtain 2x = 7y + 1. Second, subtract 1 from each side to ontain 2x - 1 = 7y. Third, divide through by 7 to obtain (2x - 1)/7 = y. Step 3: Set y to the inverse of f(x) to obtain f^(-1) (x) = (2x - 1)/7.</span>
Answer:
60°
Step-by-step explanation:
All the side lengths of the triangle have the same measurement. This makes it an equilateral triangle. By the definition of an equilateral triangle, all the angles are congruent, therefore all their measurements are the same. There are 3 total angles in a triangle, and the total sum of the angel measurements of a triangle is 180. Divide 180 with 3:
180/3 = 60
60° is your answer.
