Answer:
x = - 3 or x = 7
Step-by-step explanation:
Given
f(x) = x² - 4x + 6
If f(x) = 27, then equating gives
x² - 4x + 6 = 27 ( subtract 27 from both sides )
x² - 4x - 21 = 0 ← in standard form
Consider the factors of the constant term ( - 21) which sum to give the coefficient of the x- term ( - 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, hence
(x - 7)(x + 3) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 7 = 0 ⇒ x = 7
1 1/6 and hey you can use this website check out this website called calculator soup that’s where I get my answers :)
So, the equation would be -
1.50x + 10 = 40
and you have to find the value of x
1.50(?) +10 = 40
The value of x would be 20
1.50 x 20 = 30 +10 = 40
Your answer would be that
Daniel can ride up to 20 rides
D
Substitute the values of x and y
Divide 12 by 10.
12/10= 1.2

I hope this helps!
