Answer:
Step-by-step explanation:
Yes it is a quadratic equation
5x^2 + 40x = -7
5x^2 + 40x + 7 = 0
a = 5
b = 40
c = 7
-40/10 <u>+</u> (sqrt(1600 - 4(5)(7)))/10
-4 <u>+</u> (sqrt(1600-160))/10
-4 <u>+</u> (sqrt(1440))/10
-4 <u>+</u> 12(sqrt(10))/10
-4 <u>+</u> 6/5(sqrt(10))
Average change would be : -24/6
simplified, would be : -4......so the temperature changed -4 degrees every week for 6 weeks
Answer:
No
Step-by-step explanation:
This is not an equation since it does not contain an equal (=) sign and instead contains a less than (<) sign making it an inequality.
