Question 5 (4 points) (06.07 HC) Which expression is equivalent to 8x − 2x + 4 and why? (4 points) a 4 + 6x, because (8x − 2x) + 4 = 6x + 4 = 4 + 6x b 10x, because 8x − 2x + 4 = 6x + 4 = 10x c 8x + 2x, because 8x − (2x − 4) = 8x + 2x d 14x, because 8x − 2x + 4 = 8x + 6x = 14x

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
