First step is to factorize the given expression as follows:
2x^2 + 7x - 15 = (2x-3)(x+5)
This means that the two roots of the equation are 3/2 (or 1.5) and -5
Now, we will get r and s:
we are given that the value of r is greater than the value of s, since 1.5 is greater than -5, therefore:
r = 1.5
s = -5
Answer: No he is not correct.
Step-by-step explanation: The absolute value of 5 is 5. The absolute value of -5 is also 5.
The temperature starts at 85 degrees.
t = 85
After 1 minute, it loses 3.5 degrees.
t = 85 - 3.5
After 2 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 2
After 3 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 3
etc.
After 12 minutes, it loses another 3.5 times 12 degrees.
t = 85 - 3.5 * 12
Answer:
• If h(x) is 17, equate the whole function to 17
