Answer:

Equation is true no matter what number you plug in for n.

Step-by-step explanation:

4n + 6 -2n = 2(n + 3)

First we can divide the equation by 2 on both sides.

2n + 3 - n = n + 3

n + 3 = n + 3

n = n

Since n = n, this equation is always true no matter what number you plug in for n.

The equation of a quadratic is =2^2+3−2and after you factorizing 2^2+3−2=0you got x = -2 and x = 1/2 and the curve crosses the y
Lelechka [254]

Given the next quadratic function:

y=2x^2+3x-2

to sketch its graph, first, we need to find its vertex. The x-coordinate of the vertex is found as follows:

x_V=\frac{-b}{2a}

where <em>a</em> and <em>b</em> are the first two coefficients of the quadratic function. Substituting with a = 2 and b = 3, we get:

\begin{gathered} x_V=\frac{-3}{2\cdot2} \\ x_V=-\frac{3}{4}=-0.75 \end{gathered}

The y-coordinate of the vertex is found by substituting the x-coordinate in the quadratic function, as follows:

\begin{gathered} y_V=2x^2_V+3x_V-2 \\ y_V=2\cdot(-\frac{3}{4})^2+3\cdot(-\frac{3}{4})-2 \\ y_V=2\cdot\frac{9}{16}+3\cdot(-\frac{3}{4})-2 \\ y_V=\frac{9}{8}-\frac{9}{4}-2 \\ y_V=-\frac{25}{8}=-3.125 \end{gathered}

The factorization indicates that the curve crosses the x-axis at the points (-2, 0) and (1/2, 0). We also know that the curve crosses the y-axis at (0,-2). Connecting these points and the vertex (-0.75, -3.125) with a U-shaped curve, we get:

Find the slope and​ y-intercept of the line whose equation is 2 x plus y equals 3 (2x+y=3).
jolli1 [7]
You can solve this equation by rearranging the 2x to the opposite side, but since it's a positive, you must change it to a negative. If the number was negative, it would've been a positive.
y=-2x+3
-2x is the slope and 3 is the y-intercept.
Hope this helped!

In a rectangle, one side is twice as long as another side. The perimeter of this rectangle is how many times as long as his shor
Ede4ka [16]

Answer: 6 times

Step-by-step explanation:

Let the Length of the rectangle be L and the Width be W

Also , let us pick the Length as the longest side , then from the statement

L = 2W

The perimeter of a rectangle is given as :

P = 2 ( L + W )

substitute L = 2W into the formula , we have

P = 2 ( 2W + W )

P = 2 (3W)

P = 6W

Therefore the Perimeter is 6 times as long as the Width
