Write the function in vertex form, and identify its vertex. g(x) = 5x2 - 50x + 128
steposvetlana [31]
Hello : 
<span>g(x) = 5x² - 50x + 128    
       = 5(x²-10x +128/5)
       = 5 (x²-10x+5²-5² +128/5)
        = 5 ((x-5)² +128/5 -125/5)
y = 5 ((x-5)² - 3/5)
y= 5(x-5)² +3.....vertex form
the vertex is : (5,3)</span>

neonofarm [45]

Answer:

x > 8

x < -16

Step-by-step explanation:

2x + 10 > 26

2x + 10 - 10 > 26 - 10

2x > 16

2x/2 > 16/2

x > 8

2x + 10 < -26

2x + 10 - 10 < - 26 - 10

2x < -36

2x/2 < -36/2

x < -16

elena55 [62]

Answer:

x = ± \sqrt{y-7}

Step-by-step explanation:

Given

y = x² + 7 ( subtract 7 from both sides )

y - 7 = x² ( take the square root of both sides, thus

x = ± \sqrt{y-7}

Work out the percentage change when 1.20 is increased to 1.80
exis [7]

Answer:

Step-by-step explanation:

PERCENT CHANGE

The percentage change from 1.20 to 1.80 is 50 %

 

Our percent calculator uses this formula:

((y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)

((1.80 - 1.20) / 1.20) * 100 = 50 %
