geniusboy [140]3 years ago
6 0

Answer:

Equation have Unique solution i.e x=-20

Step-by-step explanation:

Given Equation:

-6(x+7)=-4x-2

Solving the Equation for 'x'.

           -6(x)-6(7)=-4x-2\\\\-6x-42=-4x-2

Adding '4x'  both sides:

             -6x+4x-42=-4x+4x-2\\\\-6x+4x-42=-2\\\\-2x-42=-2

Adding '42' both sides:

               -2x-42+42=-2+42\\\\-2x=40

                        x=\frac{40}{-2} \\\\x=-20

The equation have Unique solution with the value of x=-20

Erin is flying a kite. She knows that 260 feet of the kite
lianna [129]

Answer:

100 ft high

Step-by-step explanation:

We know that Erin, the kite, and her friend create a right triangle since the friend is standing directly under the kite and in front of Erin.  

Thus, we can use the Pythagorean theorem to find the height of the kite.

We can let the side the distance be at represents Erin and the kite's distance be EK (aka the hypotenuse), the side that represents Erin and her friend's distance be EF and the side that represents the kite and the friend's distance be KF.

The theorem says that a^2 + b^2 = c^2, where a and b are the two shortest sides and c is the hypotenuse.

We already have the measure of the hypotenuse (260 ft) and one of the shorter sides (240), so we have:

KF^2+240^2=260^2\\KF^2+57600=67600\\KF^2=10000\\\sqrt{(KF^2=10000)} \\KF=100
