Answer:
x = - 1, x = 
Step-by-step explanation:
Given
8x² + 7x - 1 = 0 ← in standard form
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 8 × - 1 = - 8 and sum = + 7
The factors are + 8 and - 1
Use these factors to split the x- term
8x² + 8x - x - 1 = 0 ( factor the first/second and third/fourth terms )
8x(x + 1) - 1(x + 1) = 0 ← factor out (x + 1) from each term
(x + 1)(8x - 1) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
8x - 1 = 0 ⇒ 8x = 1 ⇒ x =
The answer to the question is 42ft.
Answer:
C (-6, 2)
Step-by-step explanation:
in order to solve this system of equation, we would say that let
y = 5x + 32................................equation 1
y = -4x - 22.........................................equation2
substitute equation 1 into equation 2
we have,
5x + 32 = -4x - 22
combine the like terms
5x +4x + 32 = -22
9x = -22-32
9x = - 54
divide both sides by the coefficient of x which is 9
9x/9 = -54/9
x = -6
put x =-6 into equation 1
y = 5x + 32................................equation 1
y = 5(-6) + 32
y = -30 + 32
y = 2
therefore the value of x and y is -6 and 2 respectively
Answer:
x - 5 = x - 2 and
x - 5 = 2 - x.
Step-by-step explanation:
x - 5 may be positive or negative so we have:
x - 5 = x - 2
and
x - 5 = - (x - 2)
x - 5 = 2 - x.
