Answer:
(4, - 2 )
Step-by-step explanation:
Given the 2 equations
x = 4 → (1)
- y =
x → (2)
Substitute x = 4 into (2)
- y =
× 4 = 2 ( multiply both sides by - 1 )
y = - 2
Solution = (4, - 2 )
Given
Ravi has $445 in his savings account.
He wants to save at least $795.
Write and solve an inequality to determine how much more money Ravi must save to reach his goal.
To proof
As given
amount of money in dollars Ravi must save to reach his goal be = d
Ravi has in his savings account = $445
He wants to save at least $795
than the inequality become in the form

thus $350 Ravi must save to reach his goal.
Hence proved
Answer: Add 9 to both sides to complete the square
Step-by-step explanation:
The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:
(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.
(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)
Answer:
30 centimeters
Step-by-step explanation:
You have to find the scaling of the lengths first, and to do that, you divide the 20 by 8, which would be 2.5. After, you multiply 2.5 by 12 to get your answer.
