Completing the square
7/2=3.5
3.5^2=12.25
add that to both sides
x<span>²-7x+12.25+3=12.25
factor perfect square
(x-3.5)</span><span>²+3=12.25
minus 3 both sides
(x-3.5)</span><span>²=9.25
square root both sides
x-3.5=+/-√9.25
add 3.5 to both sides
x=3.5+/-√9.25
x=3.5+√9.25 or 3.5-√9.25</span>
Answer:
Volume of a in z = 876 ounces
Step-by-step explanation:
For z, the ratio of x and y is 3 : 11
x : y = 3 : 11 , which means in 14 parts of solution z : x will be 3 parts and y will be 11 parts
So, in 2520 ounces solution of z ,
Volume of a in z = { Volume of a in x + Volume of b in x }
Therefore,
So, Volume of a in z = 876 ounces
Answer:
If the graphs of the equations intersect, then there is one solution that is true for both equations.
Step-by-step explanation:
Midpoint = ((x1+x2)/2 , (y1+y2)/2) = (2+14)/2), (1+(-8)/2) = (8,-3.5)
Plug in -2 for x and evaluate.
<span>f(-2) = (-2)^4 + 3(-2)^3 - 6(-2)^2 + 3
f(-2) = 16 - 24 - 24 + 3
f(-2) = -29
-2 is not a zero of the polynomial.
