Answer:
3/22
Step-by-step explanation:
-1/4 . (-6/11)
- You have to multiply the signs: As both are negative, the result will be positive.
- You have to multiply the numbers in the top part (numerators) and the numbers in the bottom part (denominators)
1 . 6 / 4 . 11 = 6/44
- Finally, you must simplify the answer by dividing both numbers among the same divisor, in this case the number is 2
6÷2 / 44÷2 = 3/22
Answer:
if i got you question right then its x=(-13/7) x=(-3/(2+b))
Step-by-step explanation:
to find the roots you need to make it equal to 0.
(x+6x+13)(2x+bx+3) =0
(7x+13)((2+b)x+3) =0
now there are 2 cases:
-> 7x+13=0 7x=(-13) x=(-13/7) solved
-> (2+b)x+3=0 (2+b)x=(-3) x=(-3/(2+b)) solved
Hi there,
4x - 5y = 39
y = 6x - 13
4x - 5(6x - 13) = 39
4x - 30x + 65 = 39
-26x = 39-65
-26x = -26
x= -26/-26
x= 1
So we deduce y now :
y = 6 *1 - 13
y= 6 - 13 = -7
Hope this helps !
