<span>7r²+9=1
</span><span>the equation is contradictory, just to prove
7r</span>² + 9 = 1
7r² + 9 -1 = 0
7r² + 8 = 0
<span>We write the equation in the form of products of
</span>
7 * (r² + 8/7) = 0
<span>the product is equal to 0 when one of the factors is zero
</span>
7≠0 ∨ (r² + 8/7) = 0
r² ≠ - 8/7
<span>any number squared is not negative.
</span><span>We proved that none of the factors is not equal to zero , so the right side of the equation is not equal to the left . The equation is contradictory</span>
You just divide 26 by 60 and you get .4333 repeating. To make the decimal a percent you just move the decimal place two places to the right and get about 43%.

The reflection of the triangle across <span> y = -x</span><span> is the new triangle.</span>
Step-by-step explanation:
A flagpole is 53 feet tall. Most of the time, this will be a vertical side of the triangle.
The flagpole and the ground are perpendicular to each other so they should form the legs of the triangles, this the triangle will be a right angle.
The rope will be the hypotenuse, the side opposite of the right angle.
