Answer:
2
Step-by-step explanation:
4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2. Please use
" ^ " to indicate exponentiation.
Rewrite 4x = 32 - x^2 in the standard form of a quadratic: x^2 + 4x - 32
Then the coefficients are a = 1, b = 4 and c = -32.
Find the discriminant. It is b^2-4ac.
Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.
Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.
So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."
Answer:
$(400+80x)
Step-by-step explanation:
We are required to find the total income on Friday Night
Ticket costs $5 each and they sold 80 tickets
Total ticket Sales = 80 X $5 =$400
There was a donation of $x per ticket, so for 80 tickets, there was a donation of $80x.
Total Income on Friday Night=Ticket Sale+Donations= $(400+80x)

Answer:
z = -4 1/2
Step-by-step explanation:
1. First change the mixed fractions to improper fractions so it's easier
2. Simplify
3. Cross multiply
4. Simplify again (distributive property)
5. Distributive property
6. Subtract 32 from both sides
7. Simplify
8. Subtract 80 from both sides
9. Simplify
10. Divide both sides by 16
11. Simplify
Sorry if it was too long but hope this helps! :)
And also try using symbolab cuz it gives step by step explanations it's really good!
