180/480 =0.375
0.375 = 37.5%
so 37.5% of kids are in 9th grade
Answer:
m = slope
(x_1, y_1) = coordinates of first point in the line
(x_2, y_2) = coordinates of second point in the line
Answer:
Step-by-step explanation:
Given the expression 
, we will use laws of indices to get the equivalent expression as shown below;
According to one of the law of indices,
This gives the required expression
Let’s say we have 1 and 3.
3-1=2
Thats an even number, so false, but lets check some more just to be sure:
27-3=24 (even)
13-5=8 (even)
75-3=72 (even)
So, the answer is false.
Answer:
2x^{2}-3x-5 = 0
use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x= 5/2, -1
