Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?

maxonik [38]

ANSWER

$2 \frac{1}{4}$

EXPLANATION

We want to find the constant that must be added to

${x}^{2} - 3x$

to form a perfect square.

Comparing the given expression to

$a{x}^{2} + bx + c$

we have

a=1 , b=-3 , and c=0.

We need to add

${( \frac{b}{2a} })^{2}$

We substitute the values to get,

${( \frac{ - 3}{2(1)} })^{2} = \frac{9}{4}$

We change this to mix numbers to get,

$2 \frac{1}{4}$

The last choice is correct.

half of an integer exceeds one _ third of the next integer by unity .Find the integer. please ask fast

gulaghasi [49]

9514 1404 393

Answer:

Step-by-step explanation:

If the integer is n, half of it is n/2. The next integer is (n+1) and 1/3 of it is (n+1)/3. You want ...

n/2 - (n+1)/3 = 1

n(1/2 -1/3) -1/3 = 1

n/6 = 4/3 . . . . . . . . add 1/3, simplify

n = 6(4/3) = 8

The integer is 8.

Consider the system of equations.

Harman [31]

The solution to the system of equations x + 2y = 1 and -3x-2y = 5 is:

x = -3, y = 2

The given system of equations:

x + 2y = 1............(1)

-3x - 2y = 5..........(2)

This can be written in matrix form as shown:

$\left[\begin{array}{ccc}1&2\\-3&-2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}1\\5\end{array}\right]$

Find the determinant of $\left[\begin{array}{ccc}1&2\\-3&-2\end{array}\right]$

$\triangle = 1(-2) - 2(-3)\\\triangle = -2+6\\\triangle = 4$

$\triangle_x = \left[\begin{array}{ccc}1&2\\5&-2\end{array}\right]\\\triangle_x = 1(-2)-2(5)\\\triangle_x = -2-10\\\triangle_x =-12$

$\triangle_y = \left[\begin{array}{ccc}1&1\\-3&5\end{array}\right]\\\triangle_y = 1(5)-1(-3)\\\triangle_y = 5 + 3\\\triangle_y =8$

$x = \frac{\triangle_x}{\triangle} \\x = \frac{-12}{4} \\x = -3$

$y = \frac{\triangle_y}{\triangle} \\y = \frac{8}{4} \\y = 2$

The solution to the system of equations x + 2y = 1 and -3x-2y = 5 is:

x = -3, y = 2
