Answer:
Step-by-step explanation:
<u>As per graph, using the points (-6, 0) and (0, 3) we determine that:</u>
- the y-intercept is 3 and
- the slope is m = (3-0)/(0 - (-6)) = /3/6 = 1/2
<u>So the equation is:</u>
450,000 is your answer:) hope I helped
Answer:
1 and −1 are the only solutions to the equation x^2 = 1.
Step-by-step explanation:
We shall proceed as he suggests
Given
substitute a+bi in x, we get
Rewriting the both sides in standard form for a complex number
Equating the real parts on each side of the equation, and equating the imaginary parts on each side of the equation.
and
So either a=0 or b=0. If a=0 then
. has no real solution.
If b=0 then
. or
Hence proved.
Answer:
830 cents
5n + p
Step-by-step explanation:
Given that :
Number of nickels = 140
Number of pennies = 130
Total coins :
140 nickels + 130 pennies
1 nickel = 5 cent
1 penny = 1 cent
Hence,
140(5) + 130(1)
700 + 130
= 830 cents in total
If :
number of nickels = n
Number of pennies = p
Tot coins :
5n + 1p
5n + p
