there was a saline solution in a container. its concentration was 10% at first. when 60g of salt was added, the concentration became 25%. find the weight of 10% saline solution at first

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

the answer is (-8,-5)

step-by-step explanation:
