Find the value of X in the triangle shown.
zalisa [80]
X = 12

Use the Pythagorean Theorem.
13^2 = 5^2 + x^2
169 = 25 + x^2
Subtract 25 from both sides.
144 = x^2
Take the square root.
12 = x

quadrilateral kstu has vertices at (7,0) (4,-6) (0,-2) and (0,0). rotate 180 degrees around the origin
solong [7]

Step-by-step explanation:

so basically for this on u have to draw this on graph every first number of the coordinate is on x axis e.g . (7,0) 7 is on x axis and 0 is on Y axis. you can use tracing paper for this which will be more helpful as u can trace the shape and move it half way.

As u rotate it around the origin so u just turn it half way. eg I drawn it on the picture.

hope this make sense :)

A walking path across a park is represented by the equation y = -4x + 10. A new path will be built perpendicular to this path. T
kodGreya [7K]

Answer:  y=\frac{1}{4}x-7

Step-by-step explanation:

The perpendicular slope of the line(m) = -\frac{1}{m}:

  • m = -4 ⇒ -\frac{1}{m} =-\frac{1}{(-4)} =\frac{1}{4}

The function formula is y = mx + b, where the y-intercept(b) is found by substituting in the values of a point on the line ⇒ (4, -6):

y=\frac{1}{4}x+b\\-6=\frac{1}{4}(4)+b\\-6=1+b\\b=-6-1=-7

<u>So the perpendicular equation is </u>y=\frac{1}{4}x-7<u>.</u>
