Answer:
x=3/22 ; y=-9/44
Step-by-step explanation:
1/2x+1/3=4
=>1/2x=4-1/3
=>1/2x=(12-1)/3
=>1/2x=11/3
=>22x=3
=>x=3/22....(1)
then,
3x+2y
2y=-3 . (3/22)
y=-9/44
Hi!
We are given the information found in the picture below.
Note: The directions aren't correct, but the triangle works for this problem.
The "direct path" is the hypotenuse of this triangle.
To find this, we use the Pythagorean Theorem, where
and
are 2 legs of the triangle, and
is the hypotenuse, aka the longest side of any triangle:
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
We know
and
and want ![c](https://tex.z-dn.net/?f=c)
![4^2+5^2=c^2](https://tex.z-dn.net/?f=4%5E2%2B5%5E2%3Dc%5E2)
![16+25=c^2](https://tex.z-dn.net/?f=16%2B25%3Dc%5E2)
![41=c^2](https://tex.z-dn.net/?f=41%3Dc%5E2)
Therefore,
is approximately ![6.403](https://tex.z-dn.net/?f=6.403)
Answer: -3
Step-by-step explanation: well there is a pretty easy explanation for this because what you pretty much do is you put the answer around by doing 5-2 and just put a negative since the smaller number is in the front.
B,D is the answer for your question
The y-intercept is 60
the slope is 30
the equation of the line is y=30x+60
the ordered pair (4,120) represents and increase of 30 minutes per hour
