Since we're starting with a negative we're going to disregard the negative sign and add the numbers together: $10.28 + $39.89 = $50.17. :)
(x + 3) ( x + 1 )
because 3 x 1 = 3 and 3 + 1 = 4 , which gives you 4x.
Substituting the given information into the formula gives
0 = 48t - 16t²
Factoring, this becomes
0 = 16t(3-t)
The ball is at ground level when t=0 or t=3.
The ball hits the ground after 3 seconds.
-k-5k=-5k-4
Combine -5k and -k = -6k
-6k=-5k-4
add 5k to -6k which equals -1k
divide -1 by -4
answer k=4
Given:
1st letter : 2.9 ounces
2nd letter: 4.1 ounces
f(1) = 0.42 + 0.20(x-1)
f(1) = 0.42 + 0.20(2.9-1)
f(1) = 0.42 + 0.20(1.9)
f(1) = 0.42 + 0.38
f(1) = 0.80
f(2) = 0.42 + 0.20(4.1-1)
f(2) = 0.42 + 0.20(3.1)
f(2) = 0.42 + 0.62
f(2) = 1.04
0.80 + 1.04 = 1.84 last choice
