B. CPI %age = 82.4 - 29.6 = 52.8 / 29.6 * 100 = 178%
0.14 * 178/100 = $0.249 / $0.25 hence answer is B

X^2-3x=7/4 <br> Solve by completing the square
padilas [110]

Answer:

Step-by-step explanation:

X^2-3x=7/4 should first be rewritten in standard form, which here would be:

x^2 - 3x - 7/4 = 0.

1.  Identify the coefficient of the x term and take half of that number:

    -3/2

2. square this result:  (-3/2)^2 = 9/4

3.  add this last result, 9/4, between the -3x term and the -7/4 term, and then      subtract it as shown:

     x^2 - 3x + 9/4 - 9/4 - 7/4 = 0

4.  Rewriting the first 3 terms as the square of a binomial, we get:

    (x - 3/2)^2  -  16/4 = 0, or    (x - 3/2)^2  =  16/4

5.  Take the square root of both sides, obtaining:

     x - 3/2 = ±√4/2 or ±√2

6.  Write out the two roots:  x = 3/2 + √2

     and                                   x = 3/2 - √2

To solve the equation 2x−3=3x−7 , Esin graphs the functions f(x)=2x−3 and g(x)=3x−7 on the same set of coordinate axes.
Alecsey [184]
We have that

<span>f(x)=2x−3
g(x)=3x−7

2x-3=3x-7-------------> 3x-2x=-3+7-------> x=4 
find the value of f(x) or g(x) for x=4
</span>f(x)=2x−3 ------->  f(4)=2*4-3------> f(4)=5
<span>the solution is the point (4,5)

using a graph tool
see the attached figure

</span><span>statement

case a) </span><span>The solution of the equation cannot be found graphically. Esin should solve the equation algebraically.
this is not correct

case b) </span><span>The solution of the equation is the y-intercept of the linear equations.
</span>this is not correct

case c)<span>The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.
</span>this is correct

case d) <span>The solution of the equation is the y-coordinate of the ordered pair where the graphs of the two functions intersect
this is not correct

the answer is 
</span>case c) The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.

What is the quotient of Negative 3 over 8 and Negative one-third?
a_sh-v [17]
-3/8 divided by -1/3

Do the reciprocal of -1/3 and change the division sign to a multiplication sign.

-3/8 x -3/1

Multiply the numerators and denominators

-3 X -3 = 9
8 X 1 = 8

As an improper fraction, it is 9/8.
As a mixed number it s 1 1/8
