vertex is (h,k)
given
y=1(x-2)^2-5
the vertex is (2,-5)
tha'ts quadrant 4
andswer is 2nd one
3/22 but in a decimal 0.1363
Answer:
Désolé, mon français est terrible, je vais donc utiliser traduction automatique ici.
x est approximativement égal à 0.906 et -1.656
Step-by-step explanation:
x + (2x + 3) + 4x² - 9 = 0
4x² + x + 2x + 3 - 9 = 0
4x² + 3x - 6 = 0
Nous ne pouvons pas prendre en compte cela, nous allons donc passer par la résolution de x à la place.
Commençons par compléter le carré:
4x² + 3x = 6
4x² + 3x + 9 / 16 = 6 + 9 / 16
(2x + 3/4)² = 96 / 16 + 9 / 16
(2x + 3/4)² = 105 / 16
2x + 3/4 = ± √105 / 4
2x = -3/4 ± √105 / 4
2x = (-3 ± √105) / 4
x = (-3 ± √105) / 8
x ≈ 0.906, -1.656
Answer:
(n-4)(n-1)
Step-by-step explanation:
n2 -5n +4
n2- n - 4n - 4
n(n-1) - 4(n-1)
(n-4)(n-1)
It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.

Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept.
Let x represent the rate of cost of one loaf and y represent the total cost, hence:
y = 0.8x + 100
The rate of cost of one loaf is $0.8 and the start up cost is $100.
For the second bread it is given by:
y = 1.6x
The graph of the two equations cross at (125, 200)
It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.
