So, you start out with 100 students. 85% are good students, so 85 good students. If 10 more good students were to join the school, then your total of 100 would increase by 10. 100+10=110. Your number of good students would also increase by 10. 85+10=95. To find the new percent, do division. 95/110 rounds to 86%.

Using translation concepts, the graph of function g(x) = f(x) - 2 = x² - 2 is given at the end of the question.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the functions are given as follows:

  • f(x) = x².
  • g(x) = f(x) - 2 = x² - 2.

Which means that g(x) is a shift down of 2 units of f(x), as given by the graph in the end of the question.

For the equations given below, which statement is true?
seraphim [82]

Answer:

D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first

equation by any value

Step-by-step explanation:

-21=14 Equ(1)

6.1=-42 Equ(2)

Multiplying the first equation by -3 will give

-63= -42

Which is not equivalent to the second equation

Multiplying the first equation by 3, we have

-63=42

Not equivalent to the second equation

Multiplying both sides of the first equation by -4, we have

84=56

Not equivalent to the second equation

D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first

equation by any value
