Answer:
This is a help site, so I'll explain each property and see if you can match them yourself.
Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.
Commutative Property of Addition - same as the associative property but with 2 numbers.
Identity Property of Multiplication - Any number multiplied by one is itself
Multiplicative Property of Zero: x * 0 = 0
Associative Property of Multiplication - Same as that of addition, yet with multiplication.
Distributive Property: Factoring Out.
EX: (12 x 15) = 3(4 x 5)
Answer:
x: (-5.0)
y: (0, -17.5)
Step-by-step explanation:
The x-intercept of the line is when y=0. In the table is the point (-5,0). This is the x-intercept.
To find the y-intercept, find when x=0. Write an equation for the table in y=mx + b. Find the slope between two points first.

The slope is -3.5. So the equation is
y - 7 = -3.5(x--7)
y - 7 = -3.5 (x+7)
y - 7 = -3.5x - 24.5
y = 3.5x - 17.5
Since it is in y=mx+b, b= -17.5 and this is the y-intercept.
40= 1,2,4,5,8,10,20,40
48= 1,2,3,4,6,8,12,16,24,48
the gcf is 8.
