Mathematics

Answer:

1 = 157°

2 = 23°

Step-by-step explanation:

because the angles are supplementary, their angles will add up to 180°
set up the equation (2x-3)+(-5x+423)=180
combine like terms to get -3x+420=180
subtract 420 from 180 to get -3x=-240
divide by three and get x=80
now plug in 80 for x in both equations

The parent function f(x) = x2 is translated such that the function g(x) = –x2 + 6x – 5 represents the new function.

zhenek [66]

Answer:

g(x) has an axis of symmetry at x = 3.

g(x) is shifted right 3 units from the graph of f(x)

g(x) is shifted up 4 units from the graph of f(x).

Step-by-step explanation:

The parent function is:

$f(x)=x^2$

The transformed function is $g(x)=-x^2+6x-5$ .

This new function can be rewritten in the vertex form as:

$g(x)=-(x-3)^2+4$

This function is obtained by shifting the parent function 3 units right and 4 units up.

The axis of symmetry is x=3;(x=h) and h=3.

There is no horizontal stretch or compression.

The new function is however reflected in the x-axis

For the function f(x)=−x^2+x−7, find f(1)

tino4ka555 [31]

Answer:

f(1) = -7

Step-by-step explanation:

Step 1: Define

f(x) = -x² + x - 7

f(1) = x = 1

Step 2: Substitute and Evaluate

f(1) = -(1)² + 1 - 7

f(1) = -1 + 1 - 7

f(1) = -7
