Answer:
2
Step-by-step explanation:
ok so let's start
were starting off with -3/4 and were adding 2 3/4 to that and it's equal to 2 3/4 subtract 3/4
-3/4 + 2 3/4 = 2 3/4 - 3/4
2 3/4 - 3/4 = 2
-3/4 + 2 3/4 = 2
it's 2 my dude or girl i don't know
Answer: 
Step-by-step explanation:
For this exercise it is necessary to remember the following:
1) The Distributive Property states the following:
2) The multiplication of signs:
Knowing this, and having the following expression given in the exercise:
You can apply the Distributive property multiplying 
and 
, which are inside the parentheses, by 
.
So, you get the following result:
E Value of the Expression a. 50 times the sum of 64 and 36. 50 x(64+36)
After the 2 angles the third and fifth line are great
Answer:
y = (-16t-2)(t-1)
To find the zeros, let's set y = 0 and separate these two expressions in parenthesis with the zero product property.
0 = -16t-2
0 = t-1
Now let's solve for t and get two zeros.
0 = -16t-2
2 = -16t
<u>t = -1/8</u>
0 = t-1
<u>t = 1</u>
1. Our two zeros are t = -1/8 and t = 1.
2. The two zeros are not both meaningful! Remember that this is modeling time, and we don't really care about -1/8 seconds. We don't need that negative time measurement, so we just want to know what's happening at 1 second. And at one second, the ball is on the ground. Great, so we know that height of ball = 0 after 1 second.
