Answer:
- 439
Step-by-step explanation:
evaluate f(- 7) and substitute the value obtained into s(x)
f(- 7) = 3(- 7) = - 21 , then
s(- 21) = 2 - (- 21)² = 2 - 441 = - 439
ANSWER: 4. Step-by-step explanation: divide number of students by the 22 students in a class to get your answer.
75 degrees warmer.
If you subtract -39 by -114, you get 75 which is the distance between the two temperatures
Answer:
<h2>(a) 5,050 psi.</h2><h2>(b) 5,051.3 psi.</h2><h2>(c) 5,180 psi.</h2><h2>(d) 4,920 psi.</h2>
Step-by-step explanation:
The given function is

Where
represents the accelerated strength in psi, and
represents 28-day standard-cured strength in psi.
Part a is about finding the y-value for 

Therefore, the expected value of 28-day strength when accelerated strength is 2,500, is 5,050 psi.
Part b is about the y-value for 

Part c is about the y-value for 

Part d is about the y-value for 

Answer:
r = -1/2
Step-by-step explanation:
3(5 + 4r) = -18r
15 +12r = -18r by distributive property
15 = -12r - 18r
15 = -30r
r = - 1/2r
