Mathematics
1 answer:
Flauer [41]3 years ago
5 0
<span>Simplifying 49x^2 + -9 = 0
Reorder the terms: -9 + 49x^2 = 0
Solving -9 + 49x^2 = 0 Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation. -9 + 9 + 49x^2 = 0 + 9
Combine like terms: -9 + 9 = 0 0 + 49x^2 = 0 + 9 49x^2 = 0 + 9
Combine like terms: 0 + 9 = 9 49x^2 = 9
Divide each side by '49'. x^2 = 0.1836734694
Simplifying x^2 = 0.1836734694
Take the square root of each side: x = {-0.428571429, 0.428571429}

hope this helps!!</span>

The diagram shows , , and . Which statement can be proven true from the diagram?
tresset_1 [31]
What can be proven true in the diagram is the statement in letter C. angle CGB is complementary to angle AGD. It is because they both had the same vertex which is point G. Complementary angles are angles which are equal to 90 degrees wherein when you add both angles which are obviously 45 degrees, the sum is 90 degrees.

_____________________________________________
Given that "a" and "b" are positive integers; and that "x" is a real number greater than "zero"; 
____________________________________________
  If a <span>≥ b ,  then:

   x</span>ᵃ /xᵇ = x⁽ᵃ ⁻ ᵇ⁾ ;

Math question down below
Ganezh [65]
Now, remember, a negative number divided by a positive number gives you a negative sum. You would, simply, divide this like a normal equation and add a negative sign.
1.53 ÷ 0.17 = 9
-1.53 ÷ 0.17 = -9

Your answer would be -9. 

I hope this helps!
