Answer:
(- 3, - 6 ) , (1, 2 )
Step-by-step explanation:
2y = 4x ( divide both sides by 2 )
y = 2x → (1)
x² + y = 3 → (2)
Substitute y = 2x into (2)
x² + 2x = 3 ( subtract 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Substitute theses values into (2) for corresponding values of y
x = - 3 : y = 2(- 3) = - 6 ⇒ (- 3, - 6 )
x = 1 : y = 2(1) = 2 ⇒ (1, 2 )
Answer:
1000
Step-by-step explanation:
After 8 hours, it becomes 1000, and because it doesn’t make it to 16 hours it stays at 1000.
We can not see the rest of 12
The answer is A because you know he scored 5 points in the first round. Then you don't know what he scored in the next rounds. You also know that the total points have to be greater than or equal to 30. Therefore the correctly set up inequality is A. Hope this helps!
7/8 and 5/8 are like fractions because they have the same denominator. To change 1/2 into a like fraction multiply by 4/4 to make 4/8.
