If 5x + x² > 100, then x is not 10 8 7 9

Answers

Answer 1
Answer: We will solve the equation:
x^2+5x-100≥0 x_(12) = (-5\pm √(25+400) )/(2)= (-5\pm20.6)/(2)      x1≈-12.8   x2≈ 7.8
It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).
Answer: C) x ≠ 7
Thank you.

Answer 2
Answer:

If inequality 5x + x² > 100, then x is not equal to 7.

The given inequality looks like you have a quadratic inequality that we have to solve,

5x + x² > 100

To determine which values of x will not satisfy this inequality,

We can use algebraic manipulation.

We can rewrite the inequality as,

x² + 5x - 100 > 0

Then, we can use the quadratic formula to find the roots of the equation, which are x = (-5 ± √(425)) / 2.

x ≈ -12.8 or 7.8

It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).

Hence, x ≠ 7

Evaluate, 2 x (390 - [5 x (10 - 4 divided by 2)] + 15) x 2= ?

Answers

the answer is 1460 because use math equations to break it down
2 * (390 - [5 * (10 - (4)/(2))] + 15) * 2= x \n 2 * (390 - [5 * (10 - 2)] + 15] * 2 = x \n 2 * (390 - [5 * 8] + 15) * 2 = x \n 2 * (390 - 40 + 15) * 2 = 2 * (365) * 2 = x \n 730 * 2 = x \n 1460 = x

I just got confused with angle AED which I need to find the value of?

Answers

Answer:

you should find the value of 112°

Angles in triangle add to 180
So 180-79-73 =28 and 180 -37-96=47
Angles around a point add to 360 so
112 + 28 + 47 = 187 then 360 - 187 = 173
So angle AED = 173 degrees
