Answer:
(3, - 9)
Step-by-step explanation:
Differentiate using the power rule
y = a , then
= na
Given
y = x² - 6x
= 2x - 6
Equate to zero since the measure of gradient is , that is
2x - 6 = 0 ( add 6 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into y for corresponding value of y
y = 3² - 6(3) = 9 - 18 = - 9, thus
(3, - 9 ) are the coordinates of the point where the gradient is zero
Answer:
This statement is False though...
Answer:
There are 120 hamburgers
There are 180 hotdogs
Step-by-step explanation:
∵ The cost of h = $2 and the cost of d = $1
∵ h + d = 300 ⇒ (1)
∵ 2h + d = 420 ⇒ (2)
Solve (1) and (2)
Subtract (1) from (2)
∴ (2h + d) - (h + d) = 420 - 300
∴ h = 120
∵ 120 + d = 300
∴ d = 300 - 120 = 180
