2-(y + 2) = 3y Solve for y

Mathematics
1 answer:
alexgriva [62]3 years ago
3 0

Answer:

y=0

Step-by-step explanation:

Reorder the terms:

2 + -1(2 + y) = 3y

2 + (2 * -1 + y * -1) = 3y

2 + (-2 + -1y) = 3y

Combine like terms: 2 + -2 = 0

0 + -1y = 3y

-1y = 3y

Solving

-1y = 3y

Add '-3y' to each side of the equation.

-1y + -3y = 3y + -3y

Combine like terms: -1y + -3y = -4y

-4y = 3y + -3y

Combine like terms: 3y + -3y = 0

-4y = 0

Divide each side by '-4'.

y = 0

hope this helps

Geometry Homework Question ​
mash [69]

Answer:

Distance is 8.485

Midpoint is (3,4)

Step-by-step explanation:

Use the points (-1,7) and (5,1)

Insert them into the equation and solve for D

D=\sqrt{x} ((5-(-1))^2 + (1-7)^2)\\D=\sqrt{x} ((6)^2 + (-6)^2)\\D=\sqrt{x} (36+36)\\D=\sqrt{x} (72)\\D=8.485

Insert points into second equation to find midpoint

(\frac{_1+5}{2} , \frac{7+1}{2}) \\(\frac{6}{2} ,\frac{8}{2} )\\(3,4)

Does anyone know how to do this?
sineoko [7]

Answer:

\boxed{\tt x=\sqrt{85} }

Step-by-step explanation:

When making a right triangle with 2 points, the distance is the hypotenuse which can be represent as "x"

To find the distance we can use the Pythagorean theorem.

\boxed{{\tt a^2+b^2=c^2}}

→ \tt a=9

→ \tt b=2

→ \tt c=x

<u>Let's Plug in the side lengths:</u>

  • \tt 9^2+2^2=x^2

<u>Evaluate 9²= </u><u>81</u><u> and 2²= </u><u>4</u><u>:</u>

  • \tt 81+4=x^2

<u>Now, add 81+4= 85</u>

  • \tt 85=x^2

<u>Take the square root of both sides:</u>

  • \tt x=\sqrt{85}
