The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
199•25%=49.75
49.75+199=248.75
248.75•7.5%=18.65625
18.65625+248.75=267.40625
therefore the answer is $248.41
Answer:
i know b only Sorry hope this helps tho
Step-by-step explanation:
its 4 because each space is 25% no matter how big or small it is. so if you land on -9 to -5 thats 25% and to -2 thats another 25% total 50% its asking for 75% so you go one more which lands on 4 making it 75%
I believe C. The temperature is -23 degrees.
This is because, a negative (absolute value) becomes positive
Which would lead for |-23| to end up being |23|
Anytime a negative absolute value is placed, it becomes a positive and a positive stays positive.
So the smallest would be C then B later D and at last A
