If we are given function f(x) vertical translation is done by adding number to end of formula for translation to up or substracting number for translation to down.
f(x) + a OR f(x) - a
Horizontal translation is done by adding number next to x variable for translation to left or substracting number for translation to right.
f(x+a) OR f(x-a)
We need to translate function <span>5 units to the left and 4 units up. That means that we need to add 5 next to x and add 4 to end of function. The result is:

Answer:
The measure of these two angles are 80° and 100°
Step-by-step explanation:
Let
x and y ----> the measure of the same side angles
we know that
The sum of of the same side angles of two parallel lines is equal to 180 degrees
x+y=180° -----> equation A
x=y-20° ----> equation B
substitute equation B in equation A and solve for y
(y-20°)+y=180°
2y=180°+20°
y=200°/2
y=100°
Find the value of x
x=100°-20°=80°
Answer: it’s the one you already but the orange dot on
Step-by-step explanation:
Given:
The area of the rectangle RSTU = 
Length of the rectangle RSTU = 
To find:
The width of the rectangle RSTU.
Step-by-step explanation:
We have,

Splitting the middle term, we get



We know that, the area of a rectangle is

Area of rectangle is product of (4x+5) and (9x-5).
Since (4x+5) is the length of the rectangle, therefore, (9x-5) is the width of the rectangle RSTU.
