Witch expression are equivalent to 4(4x + 2y + x - y) 4(5x + 3y) and 20x + 12y

4(5x+y) and 20x +4y

4(3x + y) and 12x + 4y

4(3x + 3y) and 12x + 12y​

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

i would need to see the dot plot : )

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

vertical=18cm horizontal=18cm hypotenuse=25.5
