The answer would be x=-14

first you want to get x by itself so you would divide by -2 on each side of the equation, therefore 28/-2 would be -14 is equal to the x value.

Factorize the following: <br>49x² - 25​
creativ13 [48]

Answer:

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

Polygon WXYZ is dilated by a scale factor of 3 with vertex W as the center of dilation, resulting in polygon W’X’Y’Z’. The coord
Lostsunrise [7]

Dilating polygon WXYZ will change the side lengths of the polygon

The true statement is <em>(b) the slope of WX is 3/4, and the length of W'X' is 15</em>

The coordinates are given as:

\mathbf{W = (3,2)}

\mathbf{X = (7,5)}

The slope of WX is:

\mathbf{m =\frac{y_2 - y_1}{x_2 -x_1}}

So, we have:

\mathbf{m =\frac{5-2}{7-3}}

\mathbf{m =\frac{3}{4}}

The length of WX is calculated using:

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

So, we have:

\mathbf{WX = \sqrt{(7- 3)^2 + (5- 2)^2}}

\mathbf{WX = \sqrt{25}}

\mathbf{WX = 5}

The scale factor is 3.

So, the distance W'X' is:

\mathbf{W'X' = 3 \times WX}

This gives

\mathbf{W'X' = 3 \times 5}

\mathbf{W'X' = 15}

Hence, the true statement is (b)

What is the equation of the line perpendicular to y = -4x + 3 that goes through (8, -3)?
maks197457 [2]
Perpendicular slope: opposite and reciprocal
-4 opposite and reciprocal = 1/4
Y = 1/4x + b
Plug in point
-3 = 1/4(8) + b
-3 = 2 + b, b = -5
Solution: y = 1/4x - 5
