Answer:
52 cards
Step-by-step explanation:
call the amount he started with " x "
then he bought 8 cards
so the new equation is
x+8
then he lost half of his cards
so now the equation is
(x + 8 )/2
that amount to 30 cards as per what is given in the problem
so now the equation is
( x + 8 )/2 = 30
solve using inverse operations and simplifying
( x + 8 )/2 = 30
*2 *2
x + 8 = 60
-8 -8
x = 52
Answer : No solutions
(I tried making it as detailed as possible, I apologize if you don’t understand it)
True.
The absolute value of anything is the distance that value is away from zero.
For instance, |-5 + 1| = 4
As we can see, any number that we plug into this equation will always be a number equal to or greater than zero.
<h3>Answer: 2 different real number solutions </h3>
Both solutions are irrational.
===============================================
Explanation:
The given function f(x) = 5x^2+2x-12 is in the form f(x) = ax^2+bx+c
We see that
a = 5, b = 2, c = -12
Plug those values into the discriminant formula below
D = b^2 - 4ac
D = (2)^2 - 4(5)(-12)
D = 4 - 4(5)(-12)
D = 4 + 240
D = 244
Because D > 0, this means we have two different real solutions for f(x) = 0
The value of D is not a perfect square, so those two solutions or roots are irrational.
