<em>Let </em><em>the </em><em>number </em><em>be </em><em>x</em><em>,</em><em> </em>

<em>so </em><em>Now</em>

<em>5</em><em>0</em><em>%</em><em> </em><em>of </em><em>x </em><em>=</em><em> </em><em>1</em><em>4</em><em>0</em>

<em>5</em><em>0</em><em>/</em><em> </em><em>1</em><em>0</em><em>0</em><em> </em><em>*</em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>4</em><em>0</em>

<em>0</em><em>.</em><em>5</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>4</em><em>0</em>

<em>x </em><em>=</em><em> </em><em>1</em><em>4</em><em>0</em><em> </em><em>/</em><em> </em><em>0</em><em>.</em><em>5</em><em> </em>

<em>Therefore </em><em>x </em><em>=</em><em> </em><em>2</em><em>8</em><em>0</em>

<em>Therefore </em><em>the </em><em>number </em><em>is </em><em>2</em><em>8</em><em>0</em>

<em>Hope </em><em>this </em><em>helps </em>

Please help ....... ​
Leviafan [203]

Answer:

see explanation

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then shift left by a units

• If a < 0 then shift right by a units

Thus g(x) = (x + 3)² is a shift left of 3 units

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then shift up by c units

• If c < 0 then shift down by c units

Thus g(x) = (x + 3)² - 5

represents a 3 unit shift to the left and a shift down of 5 units
