Which ones do you need help on?
Answer:
To earn profit : 50 < c < 150 is the expression that best expresses this situation.
Step-by-step explanation:
The minimum number of cattle Mr. Riley can raise = 50
The maximum number of cattle Mr. Riley can raise = 150
Let the number of cattle is represented as c.
So, according to the question:
To make profit,
Number of cattle > 50
and Number of cattle < 150
or, c > 50
and c < 150
Hence, on combining both the expressions, we get
To earn profit 50 < c < 150 is the expression that best expresses this situation.

Step-by-step explanation:
Answer:
x-2/x-5
Step-by-step explanation:
Step 1 {x^2+x-6}/{x^2-2x-15}
Step 2 (x-2)(x+3)/x^2-2x-15
Step 3 (x-2)(x+3)/(x+3)(x-5)
=x-2/x-5
Answer:
{0, 8/5}
Step-by-step explanation:
Please present this 5r2 - 8r =0 as 5r^2 - 8r = 0 or as 5r² - 8r = 0.
Factoring out the r, we get r(5r - 8) = 0.
Setting each factor = 0 separately and finding r in each case, we get:
r = 0 and
5r = 8, so that r = 8/5.
The roots of this polynomial equation are {0, 8/5}.
