Answer:
the angle of ABC is 90 and the height of C is6.5
Answer:
p=2
Step-by-step explanation:
(3+6i) and (4+pi) is (7+8i)
3+4 = 7
6i+pi = 8i
Subtract 6i from each side
pi = 8i-6i
pi = 2i
That means p = 2
Keep in mind, the <em>d</em><em>o</em><em>m</em><em>a</em><em>i</em><em>n</em> is a set of <em>x-</em><em>values</em><em> </em>so determined by x-axis, the horizontal one.
In your case the domain appears to be any x less than or equal to zero, so third option.
Hope this helps.
Answer:
f(- 7) = - 57
Step-by-step explanation:
To evaluate f(- 7) substitute x = - 7 into f(x) = 7x - 8, since condition is
f(x) = 7x - 8 for x ≥ - 7, thus
f(- 7) = 7(- 7) - 8 = - 49 - 8 = - 57
Answer:
85%oforiginal price=selling cost
selling cost=85/100×$57=$48.45
