Algebra I

Algebra II

Step-by-step explanation:

Step 1: Define

-4x² = 5x + 9

Step 2: Rewrite

Find standard form.

Step 3: Identify Variables

a = -4

b = -5

c = -9

Step 4: Solve for x

Here we see that we get imaginary numbers.

∴ the quadratic would have no real roots.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
