Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² - 3x - 4 = 0
Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)
The factors are - 4 and + 1, since
- 4 × 1 = - 4 and - 4 + 1 = - 3, thus
(x - 4)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 1 = 0 ⇒ x = - 1
x- intercepts are (- 1, 0 ) and (4, 0 )
Answer:
x = -3
Step-by-step explanation:
1+3x=-2(x+7)
Distribute
1+3x = -2x-14
Add 2x to each side
1+3x+2x = -2x+2x-14
1+5x = -14
Subtract 1 from each side
1-1+5x= -14-1
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
The answer 16. Because it is 4 cheeses to the power of 2.
Using the distance formula, it equals sqrt(1)
