Answer:
y < 1
Step-by-step explanation:
graphing with inequality
quadratic formula:
x = <u>-b ± √(b² - 4ac)</u>
2a
7x² - x = 7
subtract 7 from both sides:
7x² - x - 7 = 0
plug values into the quadratic formula:
x = <u>-(-1) ± √((-1)²- 4(7)(-7))</u>
2(7)
simplify:
x = <u>1 ± √(197)</u>
14
Yes what is the four question
Answer:
1. Binomial 2. Trinomial 3. Trinomial 4. Polynomial 5. Polynomial 6. Polynomial 7. Trinomial 8. Binomial 9. Polynomial 10. Monomial
Step-by-step explanation:
For future references, you can use this to find out what the expression (number of its terms) is...
Monomial > One term = 2x^5
Binomial > Two terms = x^2 + 5
Trinomial > Three terms = 3x - 8 + 4x^5
Polynomial > Four terms (or more) = -7a^2 + 9b - 4b^3 + 6
Answer:
I take it you mean the average gallons lost an hour, in which case you would do 58,432.4 - 56,475.2 to get 1,597.2 to which you divide by 2 getting your final answer of 978.6
