Line 3.. It removed the 'x' from the 10, and it's adding, not subtracting.
also, may i know your rblx user?
I will send you one request, just comment below this answer.
Kilogram is a measure of mass.
pint is measured in cups.
inch is the imperial system.
centimeter is the metric system.
so it would be centimeter
Answer:
-3± √5
Step-by-step explanation:
It is given that,
m² + 6m = -4
<u>Points to remember</u>
Solution of a quadratic equation ax² + bx + c = 0
x = [-b ± v(b² - 4ac)]/2a
<u>To find the solution of given equation</u>
m² + 6m = -4
⇒ m² + 6m + 4 = 0
Here a = 1, b = 6 and c = 4
m = [-b ± v(b² - 4ac)]/2a
= [-6 ± √(6² - 4*1*4)]/2*1
= [-6 ± √(36 - 16)]/2
= [-6 ± √20]/2
= [-6 ± 2√5]/2
= -3± √5
Answer:
x = 0, - 2
Step-by-step explanation:
To find f(g(x)) , substitute x = g(x) into f(x)
f(x²) = 2x² + 1
To find g(f(x)) , substitute x = f(x) into g(x)
g(2x + 1) = (2x + 1)²
Then equating
(2x + 1)² = 2x² + 1 ← expand left side using FOIL
4x² + 4x + 1 = 2x² + 1 ( subtract 2x² + 1 from both sides )
2x² + 4x = 0 ← factor out 2x from each term on the left side
2x(x + 2) = 0
Equate each factor to zero and solve for x
2x = 0 ⇒ x = 0
x + 2 = 0 ⇒ x = - 2
solutions are x = 0, - 2
R ( x ) = 12 x ( revenue )
C ( x ) = 6.5 x + 22,000 ( cost )
a ) Break-even point : R ( x ) = C ( x )
12 x = 6.5 x + 22,000
12 x - 6.5 x = 22,000
5.5 x = 22,000
x = 22,000 : 5.5
x = 4,000
b ) R ( x ) > C ( x )
x > 4,000
The number of units that the company must sell to earn a profit is 4,001 or more.
