I don’t get it please explain more
Answer:
The discrimant of this equation is 144.
Step-by-step explanation:
First you have to move all the variables to one side to make the equation/expression into 0 by substracting 8x² to both sides :
9x² + 14x + 13 = 8x²
9x² + 14x + 13 - 8x² = 8x² - 8x²
x² + 14x + 13 = 0
It is given that the formula of discriminant is, D = b² - 4ac where a&b&c represent the number of the equation, ax²+bx+c = 0 :
x² + 14x + 13 = 0
D = b² - 4ac
= 14² - 4(1)(13)
= 196 - 52
= 144
Answer:
Step-by-step explanation:
<span>For each one . . .
=> solve the
equation for 'y'. That means massage it around until it's
in the form
of <em> y</em> = (thing1) <em>x</em> + (thing2).
=> When you do that, then 'thing1'
is the slope of the line on the graph,
and 'thing2' is the number
where the line crosses the y-axis.
=> When you have those two
numbers, drawing the line on the graph
is a piece-o-cake.</span>
