98 POINTS!! PLEASE HELP

Answer:

A) what did the student do wrong, explain why they are incorrect

B) Demonstrate and explain the correct way to answer the question.

Lauren says that two expressions 3x+4(2x+5) and 6x +5x +5 are equivalent. Simplify the expressions to determine whether or not Lauren is correct. Substitute a value for x to see if she is right.

3x+8x+20 = 6x+5x+5

11x+20 = 11x+5

She is wrong

Students answer: She is correct because both equal 11x +5. I substituted x=2 and got 27 for both

She is wrong because 27 will be the answer for ' 11x+5' only. The correct method should be

x=-15

This set of ordered pairs defines a function. {(-49,7), (-56,8), (-63,9), (-70,10)} Which table represents the inverse of the fu

Dmitrij [34]

Option A. x 7 8 9 10 y -49 -56 -63 -70 is the right answer.

Step-by-step explanation:

The inverse of a function means that the input becomes the output of the function and the output becomes input. When the function is given in the form of ordered pairs, the fiirst element of each ordered pair represents input and second element represents the output.

So, for given function: {(-49,7), (-56,8), (-63,9), (-70,10)}

The inverse will be:

{(7, -49), (8,-56), (9,-63), (10, -70)}

Hence,

Option A. x 7 8 9 10 y -49 -56 -63 -70 is the right answer.

Find b and then solve the equation:(b−5)x2−(b−2)x+b=0, if one of its roots is0.5

grigory [225]

Answer:

b = ⅓

x = ½, -1/7

Step-by-step explanation:

(b−5)x² − (b−2)x + b = 0

(b - 5)(0.5)² - (b - 2)(0.5) + b = 0

0.25b - 1.25 - 0.5b + 1 + b = 0

0.75b = 0.25

b = ⅓

(⅓−5)x² − (⅓−2)x + ⅓ = 0

(-14/3)x² + (5/3)x + 1/3 = 0

14x² - 5x - 1 = 0

14x² - 7x + 2x - 1 = 0

7x(2x - 1) + (2x - 1) = 0

(7x + 1)(2x - 1) = 0

x = 0.5, -1/7
