What is the descriminate of 9x^2+2=10x

28

Step-by-step explanation:

given a quadratic in standard form : ax² + bx + c : a ≠ 0, then

Δ = b² - 4ac ← discriminant

given 9x² + 2 = 10x ( subtract 10x from both sides )

9x² - 10x + 2 = 0 ← in standard form

with a = 9, b = - 10, c = 2

b² - 4ac = (- 10)² - (4 × 9 × 2) = 100 - 72 = 28

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
