Ok so
distance from (m,-3) to (2,-3) is 7 units
since the y value is the same, we don't even need to use distance formula
see how far 7 units from 2 is
-5 or 9
m can be -5 or 9
the point can be (-5,-3) or (9,-3)
Answer:
B
Let total number of students be x.
Ratio of boys to girls= 5:7
=5x:7x
According to question,
5x =95
Or x=95/5
x=19
Now,
Number of girls =7x
=7*19
=133
Answer: 173.82cm^2
Step-by-step explanation:
Answer:
b = -8
Step-by-step explanation:
crossmultiply
The discriminant explains how many solutions the quadratic function has. It is found using this formula:

Using the formula, there are three rules. Let's say the discriminant=d:
d<0 - No solution ø
d=0 -ONLY 1 solution
d>0 -2 solutions
In the following graph, there are no solutions as the graph does not hit the x-axis at any point.
Thereafter, the discriminant MUST be less than zero. Let's view the options check which one agrees with our answer.
A - Discriminant is greater than 0, which means two solutions. This is WRONG.
B - Discriminant is less than 0, which means no solutions. CORRECT!C- Discriminant is equal to 0, which means one solution. WRONG!
Your answer is B.
