Determine whether the equations are parallel or not for y= 3x-2 and y= 1/3x -11

Answers

Answer:

To know if these lines are parallel, you just have to look at the slope. In this case they are not.

Step-by-step explanation:

The slope is the number in front of your x. So for the first formula the slope is 3 and for the second one it is 1/3. The slope tells you in which direction the line goes, so if they are the same, that means that the lines are parallel. In this case the slopes are not the same, so the lines are not parallel.

Answer:

not parallel

Step-by-step explanation:

while the lines have a different y-intercept they do not have the same slope which they would need to be parallel. With two different slopes the lines will eventually cross.

Subtitute 2x+y=7 and 3x-y=8

Answers

Answer:

x = 3 , y = 1

Step-by-step explanation:

2x + y = 7

3x + y = 8

solution

2x + y = 7-----------(1)

3x - y = 8------------(2)

from equation 1

2x + y = 7

y = 7 - 2x-------------(3)

substitute equation 3 into equation 2

3x - y = 8

3x - (7 - 2x) = 8

3x - 7 + 2x = 8

3x + 2x = 8 + 7

5x = 15

divide through by the coefficient of x

5x/5 = 15/5

x = 3

to find y

substitute x into equation 1

2x + y = 7

2(3) + y = 7

6 + y = 7

y = 7 - 6

y = 1

[tex](x - 4) {}^{2} + (y - 3) {}^{2} = 5 {}^{2} [/tex]

The equation of the circle centered at point (4, 3) with a radius of length 5 is (x - 4)² + (y - 3)² = 5².

What is the equation of the circle with the given parameters?

The standard form equation of a circle with center (h, k) and radius r is:

( x - h )² + ( y - k )² = r²

Given that circle has a center at point (4, 3 ).

Hence:

h = 4

and k = 3

Also given that, the radius has a length of 5

r = 5

Plug these values into the above formula and simplify the equation:

( x - h )² + ( y - k )² = r²

( x - 4 )² + ( y - 3 )² = 5²

Expanding and simplifying, we get:

(x - 4)² + (y - 3)² = 25.

Therefore, the equation of the circle is (x - 4)² + (y - 3)² = 5².

Option D)  (x - 4)² + (y - 3)² = 5² is the correct answer.

It had been a tough night. It was August and still hot. The game had lasted three hours, and the players had to play offense, defense, and special teams because there were not enough players to field all positions. During the bus trip home, several of the athletes consumed multiple energy drinks in an attempt to regain their strength for a celebration party they planned to attend later that evening. Despite the odds, they had won their game.About half an hour into the trip home, a player named Joseph, a junior running back, began screaming from the back of the bus. When the coaches and athletic trainer reached Joseph's seat, they found him lying in the middle of the aisle, clenching his hamstrings and calf muscles in pain. He was yelling and wailing about his muscles cramping.When the athletic trainer examined Joseph, he discovered that the calves, hamstrings, and quadriceps of Josephs legs were in a tight and unyielding contraction. The athletic trainer immediately surmised that the athlete was cramping due to severe dehydration. To treat his symptoms, the athletic trainer coaxed the student to drink Gatorade, water, and juice. He also stretched and massaged all the muscle groups in an attempt to get the muscles to release their contraction. Ice packs were applied between stretches to help reduce the pain. After an hour, the muscle contractions in Josephs legs finally stopped.Answer these questions:Please describe the signal transmission across a myoneural junction that allows the nervous system to move the muscles of a football player during a game?
