Hi
5x²-x-4 = 0
Δ= (-1)² - 4*5*(-4)
Δ = 1 -4*-20
Δ = 1 +80
Δ = 81
√Δ= 9
as Δ ≥ 0 , so 2 solutions exist in R
S1 is : ( 1+9) /2*5 = 10/10 = 1
s2 = (1 -9)/2*5 = -8/10 = -4*2 /2*5 = -4/5
Corrects answers are A and D
Answer:
Step-by-step explanation:
A "difference" indicates subtraction is being used. The difference between these 2 numbers is found the same way we find the distance between 2 points on a number line. Since both the difference and the distance have to be positive numbers, the formula to find it is
|a - b| which is the absolute value of a - b.
If a = -52 and b = -79:
| -52 - (-79) | = | -52 + 79 | = 27 OR
If a = -79 and b = -52:
| -79 - (-52) | = | -79 + 52 | = | -27 | = 27
Answer:
9.48
Step-by-step explanation:
Add:
$29.99 + $15.00 + $9.75 = $54.74
Subtract:
$54.74 - $40.00 = $14.74
Subtract:
$14.74 - 5.26 = $9.48
Answer: $9.48
Answer:
first * can be any number greater than 6
second * can be any number larger than 16
Step-by-step explanation:
take each part alone:
multiply by 24 in both sides → * > 6
multiply by 4 in both sides → 1 > 16/*
take * to first side → * > 16
there is no specific answers you can go with 8 and 18
