Answer:

f(x) = 16x2 + 32x - 9

 

To find the "zeros", set f(x) = 0:

 

    0 = 16x2 + 32x - 9

 

The equation is solvable by factoring or by using the quadratic formula.  The factors (use the "ac" method) are:

 

    0 = (4x-1)(4x+9)

 

    x = 1/4 = 0.25 and x = -9/4 = -2.25

If x varies inversely as y, which statement is true?
grin007 [14]

Answer: The Inverse variation

Step-by-step explanation:

The phrase “ y varies inversely as x” or “ y is inversely proportional to x” means that as x gets bigger, y gets smaller, or vice versa. This concept is translated in two ways. yx = k for some constant k, called the constant of proportionality.

Mhanifa u helped me with this question.... U said it was 25 and its not so why is it wrong
Yanka [14]

Hey I don't know who Mhanifa is but 25 is correct, and I will put the entire explanation to how to get the answer here.

First of all the 2 lines on the left and right side of the triangles are means that those 2 lines are equal and thus forming a isosceles triangle.

This means that the bottom right angle is also 2x+2 degrees.

Now because all 3 angles in a triangle adds to 180 degrees, we can set up equation.

3x+1+2x+2+2x+2=180

Now combine like terms

7x+5=180

Then solve, first subtract 5 from both sides.

7x=175

Now divide 7 from both sides

x=25
