What is the missing coefficient of the x-term of the product (-x-5)2 after it has been simplified
Answers
Answer:
we have
(-x -5) to the power of 2
we know that
(-x -5) to the power of 2 = (-x -5) x (-x -5)
To multiply two binomial I can use the FOIL method
(-x -5) x (-x -5) = (-x) x (-x) + (-x) x (-5) + (-5) x (-x) + (-5) x (-5)
= X to the power of 2 + 5x +5x + 25
= x to the power of 2 +10x +25
therefore
the answer is
the missing coefficient of the x-term is 10
Answer:
10

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

5x = 24
x=4.8
Given that we have the value of x, we can now substitute it in the other equation.
y=x-8
y=4.8-8
y= -3.2
The answer is (4.8, -3.2)
