Consider the Pythagorean Theorem and its converse. Which statements are correct? A)
6,8, and 10 are possible side lengths for a right triangle,
8)
10, 15, and 20 are possible side lengths for a right triangle
The Pythagorean Theorem works only for sides of a right triangle
D)
If the sides of a right triangle are of length 8 and 15. its hypotenuse is 17.
E)
The Converse of the Pythagorean Theorem allows us to calculate side
lengths of right triangles.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

thus, the first answer choice, y = sec x, is the correct one

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be

the correct answer is the last option
