Answer:
x=-4.5 or x=-2/9(fraction)
Step-by-step explanation:
3x^2-6x-2=0 simplify so add 3 minus 6 then do ^2
-9x-2=0 Add 2 on both sides
-9x=2 divide by -9 on both sides
x=-4.5 or x=-2/9
The x is 72 because it’s sup
Step-by-step explanation:
so, it is a quadratic equation :
-3x² + 30x - 90 = 0
the first thing we can do is divide by 3
-x² + 10x - 30 = 0
remember, the formula to solve and find the 2 solutions is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case here
a = -1
b = 10
c = -30
x = (-10 ± sqrt(100 - 4×-1×-30))/-2 =
= (-10 ± sqrt(100 - 120))/-2 = (-10 ± sqrt(-20))/-2 =
= (-10 ± sqrt(4×5)i)/-2 = (-10 ± 2×sqrt(5)i)/-2 =
= 5 ± -sqrt(5)i
x1 = 5 - sqrt(5)i
x2 = 5 + sqrt(5)i
remember, i = sqrt(-1), a complex number.
Answer:
option-1
option-2
Step-by-step explanation:
Suppose, we have to find distance between x=a to x=b
so, we get distance
distance = b-a
or we can also write as
distance =|b-a|
or
distance =|a-b|
we are given
the distance between 1.8 and 9.4 on the number line
we can write distance as
distance =|9.4-1.8|
distance =|1.8-(9.4)|
so, option-1 and option-4......Answer
The x-intercept is for y = 0.
substitute y = 0 to the equation of the function:
<h3>Answer: x-intercept = -45 → (-45, 0).</h3>
