For
ax+by=c
the slope is -a/b
the slope of paralell lines are the same
fidn slope
5x+3y=15
-a/b=-5/3
paralell as same slope
answer is A
Answer:
x = 1.56 or x = -2.56
Step-by-step explanation:
From the equation;
x2 +x − 4 = 0
a = 1 , b = 1, and c = -4
x = (-b ± √(b² -4ac))/2a
= (-1 ± √(1²- 4×1×-4))/2
= ( -1 ± √(17)/2
= (-1 ± 4.12)/2
= (-1 + 4.12)/2 or (-1 - 4.12)/2
<u>x = 1.56 or x = -2.56</u>
It would be 57 and 3/5 because 57.6 as a fraction is 57 and 6/10 and that simplified is 57 and 3/5 because 6 divided by 2 is 3 and 10 divided by 2 is 5
Answer:
20
Step-by-step explanation:
