What is the axis of symmetry for f(x)=5(x+7)(x-5)

Harman [31]

<span>What is the axis of symmetry for f(x)=5(x+7)(x-5)? Multiply out this polynomial to obtain the equation of a parabola in the form y = ax^2 + bx + c.

f(x) = 5(x^2 - 5x + 7x -35)

Holding the coefficient 5, we have 1x^2 - 2x - 35. Here a = 1 and b = -2, and
thus x = -b / (2a) provides the x-coord. of the axis of symm. It is:

x = -(-2) / (2*1) = 1.

The axis of symmetry is the vertical line x = 1.</span>

0.5x-7= 0.3 solve the equation<br><br><br><br><br>

Lena [83]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{x = 14.6}}}}$ </h3>

Step-by-step explanation:

$\sf{0.5x - 7 = 0.3}$

Move 7 to right hand side and change it's sign

⇒ $\sf{0.5x = 0.3 + 7}$

Add the numbers

⇒ $\sf{0.5x = 7.3}$

Divide both sides of the equation by 0.5

⇒ $\sf{ \frac{0.5x}{0.5} = \frac{7.3}{0.5} }$

Calculate

⇒ $\sf{x = 14.6}$

Hope I helped!

Best regards!!

If the mean of 20, y, 10,5,15 is 22 find the value of y

QveST [7]

Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5
