Answer:
Step-by-step explanation:
rise/run. up 3 and over 4. so your slope is 3/4
How much would it cost altogether to ride 7 rides?
Answer:
equation: y=2.25x+5
a: 13 rides
b:$20.75 for 7 rides
explanation:
a: 35=2.25x+5
first subtract 5 from 5 and 35
30=2.25x
divide each side by 2.25
x= 13 1/3
can only go on 13 rides
b: y=2.25(7)+5
2.25×7=15.75
15.75+5=20.75
$20.75 for 7 rides
Enter your answer as an expression, like this: 42x+53
(x - 4)(x - 4)
(x + 4)(x + 4)
Prime
We have (x + 4i)(x - 4i) as the fullyfactored form of x² + 16.
To factor completely the expression x² + 16, we can use the fact that the sum of squares, in this case, x² + 16, cannot be factored further using real numbers.
However, it can be factored using complex numbers.
The expression x² + 16 represents a quadratic trinomial with no real roots. Instead, it can be factored using complex numbers and the imaginary unit, denoted by 'i.'
The square root of -1 is represented by 'i,' and we can use this concept to factor the expression.
The factorization of x² + 16 can be done as follows:
x² + 16 = (x + 4i)(x - 4i)
Here, we have used the difference of squares formula, which states that a² - b² can be factored as (a + b)(a - b).
In this case, a = x and b = 4i.
It's important to note that the factors (x + 4i) and (x - 4i) cannot be further simplified using real numbers, as 'i' represents an imaginary number.
Therefore, we have (x + 4i)(x - 4i) as the fullyfactored form of x² + 16.
