98-x2=0 solve this with the quadratic formula

Mars2501 [29]

Answer:

x∈{-7√2, 7√2}

Step-by-step explanation:

$98-x^2=0\\\\-x^2+98=0\\\\a=-1\,,\ \ b=0\,,\ \ c=98\\\\x_1=\dfrac{-0-\sqrt{0^2-4\cdot(-1)\cdot98}}{2\cdot(-1)}=\dfrac{-\sqrt{4\cdot49\cdot2}}{-2}=\dfrac{-2\cdot7\sqrt{2}}{-2}=7\sqrt2\\\\x_2=\dfrac{-0+\sqrt{0^2-4\cdot(-1)\cdot98}}{2\cdot(-1)}=\dfrac{2\cdot7\sqrt{2}}{-2}=-7\sqrt2$

Which inequality can be used to represent this problem? (HELP ASAP, IM TIMED)

Nadya [2.5K]

Propane costs $3.50 per hundred pounds,

and there is a $6 monthly delivery fee.

A family has budgeted $85 for their propane this month.

Let 'x' hundreds of pounds can the family use without going over budget

Here family has budgeted $85 for their propane.

So the cost for Propane = $ 3.5x

One month delivery fee $6

Therefore cost + delivery charge not exceed $85

So 3.5x + 6 ≤ 85

3.5x=85-6 =79

x = 22.57

Therefore 22 hundreds of pounds can the family use without going over budget
