one solution : (2 ; 3)

Step-by-step explanation:

hello :

4x + 5y =23 ...(*)

9x- 5y= 3....(**)

add (*) and (**) : 13x =26

x =26/13 = 2

put this value in (*) : 4(2)+5y = 23

5y =15

y =15/5=3

PLEASE HELP! Is the following trinomial factorable why or why not h=-4(4t^(2)-9t+2)

sineoko [7]

Answer:

h = -4(t - 2)(4t - 1)

Step-by-step explanation:

Given trinomial

h= -4(4t² - 9t + 2)

Let's try to factor 4t² - 9t + 2

First find it's zeros:

t = (9 ± √9² - 4*4*2)/(2*4)
t = (9 ± √81 - 32)/8
t = (9 ± 7)/8
t = 2 and t = 1/4

So yes, it is factorable:

4t² - 9t + 2 = 4(t - 2)(t - 1/4)
or
4t² - 9t + 2 = (t - 2)(4t - 1)

The given trinomial factored:

h = -4(t - 2)(4t - 1)
