Answer:
The u equation, a parabola
Step-by-step explanation:
This is a quadratic equation, since we have a variable 'x' raised to second power.
The vertex can be found using the formula x=-b/2a when the parabola is written as y=ax2 + bx +c.
Answer:
add
Step-by-step explanation:
Hey there!!
We have:
... f(x) = -12x + 7
... g(x) = 4x - 9
<em>Now, we will have to find f(x) = g(x)</em>
... f(x) = g(x)
<em>... </em>-12x + 7 = 4x - 9
<em>... </em>9 + 7 = 4x + 12x
<em>... </em>16 = 16x
<em>... </em>x = 16/16
<em>... x = 1 </em>
<em>Hence, the value of 'x' is 1. </em>
<em>Hope this helps! </em>
<em>Happy Thanksgiving! :) </em>
Answer: x = 6.32 or -0.32
Step-by-step explanation:
2x² - 6x + 10 = 0
No we divide the expression by 2 to make the coefficient of x² equals 1
We now have
x² - 3x + 5 = 0
Now we remove 5 to the other side of the equation
x² - 3x = -5
we add to both side square of half the coefficient of x which is 3
x² - 3x + ( ⁻³/₂)² = -5 + (⁻³/₂)²
(x - ³/₂)² = -5 + ⁹/₄
Resolve into fraction
(x - ³/₂)² = ⁻¹¹/4
Take the roots of the equation
x - ³/₂ = √¹¹/₄
x - ³/₂ = √11/₂
x = ³/₂ ± 3.32/₂
= 3+ 3.32 or 3 - 3.32
= 6.32 or - 0.32
