Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 13 → (1)
x + 2y = - 4 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = - 4 - 2y → (3)
Substitute x = - 4 - 2y into (1)
2(- 4 - 2y) - 3y = 13 ← distribute and simplify left side
- 8 - 4y - 3y = 13
- 8 - 7y = 13 ( add 8 to both sides )
- 7y = 21 ( divide both sides by - 7 )
y = - 3
Substitute y = - 3 into (3) for corresponding value of x
x = - 4 - 2(- 3) = - 4 + 6 = 2
Solution is (2, - 3 )
58^(1/2) is √58 if that is what you meant
Answer: 24 ft
Step-by-step explanation:
By the Pythagorean theorem,
Answer:
2p+17
Step-by-step explanation:
twice p = p x 2 or 2p
so, 17 more than 2p (meaning 2p is increased by 17) is equal to 2p+17
Answer:
median: 6 ; mean: 13.5
Step-by-step explanation:
The median is where you line up the numbers from least to greatest and add the 2 that are left since it was an even number and you get 6. The mean is where you add all 8 numbers and divide by 8, since that is how many numbers there are.
