D. Inequality
An expression would just contain simple arithmetic without any symbols relating two things to another.
An equation must contain an equals sign.
A fraction will have a bar representing division.
An inequality contains a sign representing a comparison of magnitude, in this question less than <.
Hope this helps!!
D.
slope = -3
passing thru(4,3)
y = mx + b
3 = -3(4) + b
b = 15
equation
y = -3x + 15
E.
(4,5)(6,9)
slope = (9-5)/(6-4) = 4/2 = 2
passing thru (4,5)(6,9)
y = mx + b
5 = 2(4) + b
b = -3
equation
y = 2x - 3
Answer:
Step-by-step explanation:
If we choose chairs having odd number in the row
no of chairs from which selection is made = 10
no of chairs to be selected = 5
no of ways = 10C₅
similarly if we choose hairs having even numbers only ,
similar to above , no of ways
= 10C₅
Total no of ways
= 2 x 10C₅
= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1
= 504 .

Answer:
Jada walked 
Elena walked 
Lin walked 
Step-by-step explanation:
Let
x----> total miles walked by Jada
y----> total miles walked by Elena
z----> total miles walked by Lin
we know that
-----> equation A
-----> 
------> equation B
------> equation C
Substitute equation C and equation B in equation A and solve for x
Find the value of y
Find the value of z
therefore
Jada walked
Elena walked
Lin walked
