Explicație pas cu pas:
Fie numărul = x
x + 4 = e - - (1)
e * 4 = f - - - (2)
Ecuația 2 - 4 împărțită la 4 = 4
(f - 4) / 4 = 4
Crucea se înmulțește
f - 4 = 16
f = 16 + 4
f = 20
Rezultatul 1 împărțit la 4 este egal cu 4
Prin urmare,
e = f / 4
f = 20
e = 20/4
e = 5
De la (1)
x + 4 = e
x + 4 = 5
x = 5 - 4
x = 1
Answer:
The correct point would be D) (6, 1.5)
Step-by-step explanation:
To find the y value, put in 6 for x in the equation and simplify.
y = x÷4
y = 6÷4
y = 1.5
Answer:
The correct answer is A.
Step-by-step explanation:
The rule with a function is every input has exactly one output. In the answer choices b, c, and d all of them has a repeating input or x value.
Use the difference of 2 squares (a - b)(a + b) = a^2 - b^2:-
(x - 1/x)(x + 1/x) = x^2 - (1/x)^2
= x^2 - 1/x^2
(x ^2 - 1/x^2)(x^2 + 1 /x^2)
= x^4 - 1/x^4
(x^4 - 1/x^4)(x^4 + 1/x^4)
= x^8 - 1 /x^8 Answer
