x = √77</em></u></h2><h2><u><em>
or</em></u></h2><h2><u><em>
x = 8.77</em></u></h2>

Step-by-step explanation:
it's a right triangle
Pythagorean theorem
the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
x² = 9² - 2²
x² = 81 - 4
x² = 77
x = √77
or
x = 8.77

Hi
4x-y=5
3x-7=2
We need to solve 3x-7=2 for x
Let's start by adding 7 to both sides
3x-7+7=2+7
3x=9
Now just divide both sides by 3 so we can find the value for x
3x/3=9/3
x=3
Now substitute 3 for x in 4x-y=5
4x-y=5
(4)(3)-y=5
-y+12=5
Now add -12
-y=12-12=5-12
-y=-7
Divide both sides by -1 so we can eliminate the negative sign
-y/-1=-7/-1
y=3
The answer is A
(3,7)
