Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur perpendicular equation is : y = -1/3x + 3
Answer:
Pants cost $20 and tee-shirts $10.
Step-by-step explanation:
For Sam 3t + 2p = 70
For Jessica 4t + p = 60
Take 2 times Jessica's equation and subtract Sam's
8t + 2p = 120
3t + 2p = 70
5t = 50
t = 10
3(10) + 2p = 70
30 + 2p = 70
2p = 40
p = 20
Hey friend, hope I can assist you!
I will solve by elimination <3.
Multiply 3x - 7y = 2 by 2: 6x - 14y = 4
6x - 14y = 4
6x - 9y = 9
5y = 5
Now we have
6x - 14y = 4
5y = 5
Now we want to solve 5y = 5 for y
So simply divide both sides by 5.
5y/5 = 5/5
This gives us one or in other words, y = 1.
Now we want to plug y = 1 into 6x - 14y = 4
So 6x - 14 * 1 = 4
This gives us
6x - 14 = 4
Now add 14 to both sides.
6x - 14 + 14 = 4 + 14
6x = 18
Now divide both sides by 6
6x/6 = 18/6
This gives us 3 so x = 3
Therefore our solutions to this system of equations would be y = 1 and x = 3
Answer: G-T-A-G-C-T
Step-by-step explanation: so A pairs with T While G pairs with C
Hey there!
In this picture, we have many pairs of adjacent angles:
1 and 2
2 and 4
4 and 3
3 and 1
This is because these pairs are being connected by a vertex and a side.
Hope it helps and have a great day!!!
