Answer:

y = 2x - 1

Step-by-step explanation:

y - 2x + 2 = 1

6x - 3y = 3​

<u />

<u />y - 2x + 2 = 1 \\  +2x  - 2    +2x  - 2\\y = 2x - 1

Plug in for y:

6x - 3(2x - 1) = 3​

6x - 6x + 3 = 3

Simplified, 3 = 3

Answer: this solution has infinite solutions

Step-by-step explanation:

original system:

y-2x+2 = 1

6x-3y = 3

Move 2 to right side of equation

y    -2x = -1

-3y+6x = 3

solve for y in first equation

⇒ y = 2x - 1

insert y into second equation

⇒ -3(2x-1) + 6x = 3

simplify

⇒ -6x+3+6x = 3

simplify once more

⇒ 3 = 3

this solution has infinite solutions

For which value of x is the equation 2(1 + x) = x + 3 true?<br><br> A) 1<br> B) 2<br> C) 3<br> D) 4
amm1812

Answer:

A) 1

Step-by-step explanation:

To solve, just plug in the numbers to the equation for x until both sides are equal to each other.

Plug in 1:

2(1 + x) = x + 3

Let x = 1:

2(1 + 1) = 1 + 3

Solve. Remember to follow PEMDAS. First, add parenthesis, then multiply. On the other side, add:

2(1 + 1) = 1 + 3

2(2) = 4

4 = 4 (True)

A) 1 is your answer.

If the area A of a triangle is 72, and the height h is equal to the length of the base b, what is the length of the base?
alexgriva [62]

Answer:

option B

Step-by-step explanation:

let the height=x

base=x

Area=½bh

72=½x•x

72×2=x²

144=x²

Answer:

Option B, 14.6 units

Step-by-step explanation:

<u>Step 1:  Find the distance of AB</u>

<u />AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

AB = \sqrt{(3 - 1)^2 + (5 - 3)^2}

AB = \sqrt{(2)^2 + (2)^2}

AB = 2\sqrt{2} or 2.83...

<u>Step 2:  Find the distance of BC</u>

BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

<u />BC = \sqrt{(3 -1)^2 + (-1 - 3)^2}

BC = \sqrt{(2)^2 + (-4)^2}

BC = \sqrt{4 + 16}

BC = \sqrt{20}

BC = 2\sqrt{5} or 4.47...

<u>Step 3:  Find the perimeter</u>

<em>AB is the same as AD and BC is the same as DC</em>

<em />2(AB) + 2(BC)

2(2.83) + 2(4.47)

5.66 + 8.94

14.6 units

Answer: Option B, 14.6 units
