What is the equation of thr function y=6/x translated 5 units to the left and 4 units up
sergij07 [2.7K]
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:
</span>f(x)= \frac{6}{x+5} +4<span>

One of the same side angles of two parallel lines is 20° smaller than the other one. Find the measures of these two angles.
Norma-Jean [14]

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°

The area of rectangle RSTU is 36x2+25x−25. The length of the rectangle RSTU is 4x+5. Which expression describes the width of the
yKpoI14uk [10]

Given:

The area of the rectangle RSTU = 36x^2+25x-25

Length of the rectangle RSTU = 4x+5

To find:

The width of the rectangle RSTU.

Step-by-step explanation:

We have,

36x^2+25x-25

Splitting the middle term, we get

=36x^2+45x-20x-25

=9x(4x+5)-5(4x+5)

=(4x+5)(9x-5)

We know that, the area of a rectangle is

Area=Length \times width

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.
