<span>y = 10x * sin(x)
y' = 10 * (x * cos(x) + sin(x))
x = pi/2
y' = 10 * ((pi/2) * cos(pi/2) + sin(pi/2)) = 10 * ((pi/2) * 0 + 1) = 10 * 1 = 10
y - 5pi = 10 * (x - (pi/2))
y - 5pi = 10x - 5pi
y = 10x</span>
Answer:
7(7x + 2)
Step-by-step explanation:
when distributed it will be 49x + 14
Let's say x is the amount of money Kelly saves. We do not know how many weeks she is saving. If she was saving for 2, then the equation would be x=5(2). However, she is saving by w weeks, so the equation is x=5w.
