Answer:
7x^2+4x-8=14
can be rewritten as
0=7x²+4x-22
everything divided by 7 to normalize
0=x²+4/7x+22/7
now throw the pq formula on this. We can treat it as a function.
the x-intercepts would be on
wait. there are indeed no real-number-solution to satisfy the given equation.
no x-intercepts, no solution. no numbers to put in for x so that the equation gives true results.
no solution in real numbers.
Have a nice day

If there are questions left, feel free to ask them
p.s. is this about imaginary numbers at university level?
There is nearly 52 weeks in a year, so 9 x 52 would be 468
2 concerts at 40 each would be 80, so 468+80 would be 548
Valerie spends 548$ a year on music entertainment.
No it is not a prime number
Hi there!
Let's solve this equation step by step!
First we collect terms on the left side. Subtract the 44x from the 5x.
Now subtract 7 from both sides of the equation.
And finally divide both sides of the equation by -39, in order to isolate the variable x.
The answer is about -33.4
