(7^1/5)^5
=(7^5/5)
=(7^1)
=7 therefore C
Answer:
(3, 10 ) and (7, 30 )
Step-by-step explanation:
Given the 2 equations
5x - y = 5 → (1)
2y - x² = 11 → (2)
Rearrange (1) expressing y in terms of x
y = 5x - 5 → (3)
Substitute y = 5x - 5 into (2)
2(5x - 5) - x² = 11
10x - 10 - x² = 11 ← rearrange into standard form
x² - 10x + 21 = 0 ← in standard form
(x - 3)(x - 7) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 7 = 0 ⇒ x = 7
Substitute these values into (3) for corresponding values of y
x = 3 → y = 5(3) - 5 = 15 - 5 = 10 ⇒ (3, 10 )
x = 7 → y = 5(7) - 5 = 35 - 5 = 30 ⇒ (7, 30 )
A rotation, because they are circles a rotation wouldn’t work.
