That little squaer angle means right angle or 90 degrees

the black line and the red line cross

therefor the oposte angles are eqal measure
7x=90+x
solve
minus x
6x=90
divide 6
x=15

x=15

Which properties of equality are used to solve the following (in no particular order)?

All except combine like terms. Since you only have 1 variable.

Hope this helps.

For a given function ƒ(x) = x2 – x + 1, the operation –ƒ(x) = –(x2 – x + 1) will result in a

Mekhanik [1.2K]

Given:

The function is:

$f(x)=x^2-x+1$

To find:

The result of the operation $-f(x)=-(x^2-x+1)$ .

Solution:

If $g(x)=-f(x)$ , then the graph of f(x) is reflected across the x-axis to get the graph of g(x).

We have,

$f(x)=x^2-x+1$

The given operation is:

$-f(x)=-(x^2-x+1)$

So, it will result in a reflection across the x-axis.

Therefore, the correct option is A.
