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
Hello!
So, we know that the length of the rectangular basketball court is 84 ft, and the width is 50 ft.
The formula for perimeter of a rectangle is:
P = 2l + 2w
This means that we need to multiply the length by two and the width by two as well.
Substitute:
P = 2(84) + 2(50)
P = 168 + 100
P = 268 ft
ANSWER:
The perimeter of the basketball court is 268 feet long.
Answer:
A
Step-by-step explanation:
The goal is to solve for y. Start by subtracting 2x from both sides. This gives you 8y=-2x+16. Now just divide both sides by 8, which gives you y=-2/8x+16/8. Finally, simplify this to y=-1/4x+2.
7x / 8 = 21
7x = 8*21
x = 24
