Please explain :)
Answer:
m=2/3.
Step-by-step explanation:
the equation for slope is y=mx+b, where m is slope. So, 2/3 is your slope.
Answer:
The Eiffel Tower in France is 575 feet taller than pyramid of khagra.
Step-by-step explanation:
We are given the following in the question:
Height of pyramid of khagra = 488 feet
Height of Eiffel Tower in France = 1,063 feet
Difference in height =
= Height of Eiffel Tower in France - Height of pyramid of khagra
Thus, the Eiffel Tower in France is 575 feet taller than pyramid of khagra.
Answer:
see explanation
Step-by-step explanation:
given the function
f(x) = x² - 6x + 8
(a)
to find the y- intercept , let x = 0 in f(x)
f(0) = 0² - 6(0) + 8 = 0 - 0 + 8 = 8 ← y- intercept
(b)
to find the x- intercepts , let f(x) = 0 , that is
x² - 6x + 8 = 0 ← in standard form
(x - 2)(x - 4) = 0 ← in factored form
equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 4 = 0 ⇒ x = 4
the x- intercepts are x = 2 and x = 4 or (0, 2 ), (0, 4 ) in coordinate form
(c)
given a quadratic in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
= -
f(x) = x² - 6x + 8 ← is in standard form
with a = 1 and b = - 6 , then
= - = - (- 3) = 3
evaluate f(3) for corresponding y- coordinate
f(3) = 3² - 6(3) + 8 = 9 - 18 + 8 = - 9 + 8 = - 1
vertex = (3, - 1 )
(d)
the axis of symmetry is a vertical line , passing through the vertex with equation
x = c ( c is the value of the x- coordinate of the vertex )
equation of axis of symmetry is then x = 3
This if quadratic formula
Solve for y.
