Answer:
No, it's not.
Step-by-step explanation:
2b + y = 15 is not an expression because it's an equation containing an equal sign. An expression cannot include inequality signs or equal signs.
Step-by-step explanation you do the inverse which is subtraction and you get y
2-2=0 15-2=13 y=13
5/8
The sectors are labeled 1,2,3,4,5,6,7,8
Numbers less than 4: 1,2,3
Multiples of 4: 4,8
We are looking for 1,2,3,4,8 = 5 choices
P (1,2,3,4,8) = Number of choices/ total
= 5/8
B. y= -2x +2
the slope is negative 2 and the point where the line crosses the y-int is 2
the sign would probably be a negative. imagine this - - - - - - and then + + +, cancel out the negatives and plus then you are left with more negatives than positive so the sign will take the negative sign.
