Solve for p and C by replacing x with 2 then multiply p and c
c = 50 + 5x = 50 +5(2) = 50+10 = 60
p = 80 - 2x = 80-2(2) = 80-4 = 76
p x c = 76 x 60 = 4560
since c = 60
the answer would be B
Answer:
you will need 6 $5 bills
Step-by-step explanation:
Best not to use "x" to denote multiplication. "x" is usually a variable name in algebra.
3 times 3/5 comes out to 9/5, which is equivalent to 1 4/5.
You'd need to draw not one but two circles and divide each circle into 5 equal "slices." Then you'd shade one circle completely and shade 4 of the 5 slices of the other circle. 9 fifths (9 slices) would be shaded in all.
We have that
F(x)=x²<span>-10x+44
</span><span>Group
terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete
the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
