2x + 5 > 9
so 2x > 9-5
2x > 4
x > 2
5x <= 30
x <= 6
answer is 2 < x <= 6
or interval notation it is (2, 6]
Answer:
57 mph
Step-by-step explanation:
just devide 342 by 6
The larger the negative number the smaller the value:
The order would be:
-4, -1/2, 1/4, 1/3, 1/2, 2/3, 2
Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i
Step-by-step explanation:
Given bi-quadratic equation is:
Substituting 
given bi-quadratic equation reduces in the form of following quadratic equation:
Let us factorize the above quadratic equation:
Since square root of a negative number cannot be found, so:
