Answer:
7(2 + y)
Step-by-step explanation:
2 more than y:
2 + y
Product... and 7
2 + y × 7
Simplify it.
7(2 + y)
Answer: 9/15 is sinP
Tangent= opp/adj
Step-by-step explanation:
This system will have 1 solution <==
** if it were to end like 0 = 4, or 2 = -3....no variables and numbers that dont equal....this means no solutions.
** if u were to end up with 5 = 5, or -9 = -9...no variables and numbers that do equal, then u will have infinite solutions
** but if u end with y = -2 or x = 5...a variable equaling a number, then u will have 1 solution
Part A
The starting amount of water is 95 cubic meters or m^3 for short. This is the y intercept because it handles the starting amount.
Then the pool is filled at a rate of 4 m^3 per minute. This is the slope, i.e. the rate of change. Because this rate of change is constant, we have a linear equation.
We go from y = mx+b to y = 4x+95
Replace x with t to get the answer.
<h3>Answer: 4t + 95</h3>
==============================================
Part B
Plug in t = 17 and compute
V(t) = 4t + 95
V(17) = 4*17 + 95
V(17) = 163
<h3>Answer: 163</h3>
===============================================
Part C
We go in reverse compared to the previous part.
This time we don't know the t value, but we are given the V(t) value instead.
V(t) = 231
4t+95 = 231
4t = 231-95
4t = 136
t = 136/4
t = 34
<h3>Answer: 34</h3>
