Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis
Answer:
2.7 hours or 2 hrs, 42 min
Step-by-step explanation:
to find the total number of sentences remaining we can multiply 130 sentences times 20 pages remaining to get
2,600 sentences
if we divide that number by 16 we'll get the number of minutes he needs to finish the novel
2600/16 = 162.5 minutes which, when divided by 60, is 2 7/10 hours
7/10 = 42/60 so it comes out to 2.7 hours or 2 hrs, 42 min
Answer:
X=-1
Y=-9
Step-by-step explanation:
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
18 line segments also for faster and better u can 6 times 3 since there is already three in a triangle.
