4x² - 20x + 28 = 3
A) x = 5
B) x = 5/2
C) x = 2/5
D) x = - 5/2
Answers
Answer:
B) x = 5/2
Step-by-step explanation:
subtract 3 from each side to get:
4x² - 20x + 25 = 0
this is the difference of 2 squares:
(2x -5)² = 0
one solution, x = 5/2
Answer:
B) x = 5/2
Step-by-step explanation:
4x² - 20x + 28 = 3
Move terms to the left side
4x² - 20x + 28 - 3 = 0
Subtract the numbers
4x² - 20x + 25 = 0
Use the quadratic formula
[tex]x =\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
4x² - 20x + 25 = 0
a = 4
b = -20
c = 25
x = [tex]\frac{-(-20)+\sqrt{(-20)^{2}-4x4x25 } }{2x4}[/tex]
Evaluate the exponent
x = [tex]\frac{20+\sqrt{400-4x4x25 } }{2x4}[/tex]
Multiply the numbers
x = [tex]\frac{20+\sqrt{400-400 } }{2x4}[/tex]
Subtract the numbers
x = [tex]\frac{20+\sqrt{0} }{2x4}[/tex]
Evaluate the square root
x = [tex]\frac{20+0 }{2x4}[/tex]
Add zero
x = 20 / 2 x 4
Multiply the numbers
x = 20 / 8
Cancel terms that are in both the numerator and denominator
x = 5/2

Which statement explains the difference between the graphs of f(x) = 4x^2 and g(x) = -8x^2 ?
A) The graph of g(x) is obtained by flipping f(x) over the y-axis and stretching vertically by a factor of 2.
B) The graph of g(x) is obtained by flipping f(x) over the x-axis and compressing vertically by a factor of 2.
C) The graph of g(x) is obtained by flipping f(x) over the x-axis and stretching vertically by a factor of 2.
D) The graph of f(x) is obtained by flipping g(x) over the y-axis and compressing vertically by a factor of 2.
Answers
Answer:
I think C is best explains
The correct option is B.
The graph of g(x) is obtained by flipping f(x) over the x-axis and compressing vertically by a factor of 2.
What is transformation?Transformation means to change. Hence, a geometric transformation would mean to make some changes in any given geometric shape.
Given are two functions f(x) = 4x² and g(x) = -8x², we need to see the transformation done in the function f(x) to give g(x).
So,
We can see that there is scale factor of 2, because it was 4 in f(x) and in g(x) it became -8 that means the graph have been compressing vertically by 2 units.
Also, the presence of minus sign, this is because the reflection has been done here about x-axis, so it becomes -8x².
According to our study we can say that the graph is reflected over x-axis and compressing vertically by 2 units.
Hence, the correct option is B.
