What number should be added to both sides of the equation to complete the square x^2+3x=6

Take half of the coefficient of x: It is 3, and half that is 3/2.

Then <span>x^2+3x=6 becomes:

</span><span> x^2+3x + (3/2)^2 =6 + (3/2)^2, and

(x+3/2)^2 = 6 + 9/4

You were not asked to solve the equation, but why not do it for the practice?

</span>Solve (x+3/2)^2 = 6 + 9/4 for x. There will be 2 values.

If you add a zero at the end it is easier to understand. 0.20 > 0.18 because 20 is greater than 18

Solve each system using substitution.<br> 4. y = 1/x + 4<br> x-y=8

liubo4ka [24]

Answer:

$y=\frac{33}{8}$

Step-by-step explanation:

$y=\frac{1}{8} +4$

Use the slope-intercept form to find the slope and y-intercept.

Slope:

0

y-intercept:

$\frac{33}{8}$

To get the answer i used a graph

then i tried just evaluating the equation

Reduce the expression, if possible, by cancelling the common factors.

$y=\frac{33}{8}$

I got the same answer so i believe this should be your Answer

We are standing on the top of a 1200 feet tall building and launch a small object upward. the object's vertical position, measur

romanna [79]

Answer:

h = 1600 feet

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The projectile formula is

h(t) = a*t^2 + v*t + h0

Where,

v = initial vertical velocity of the object in feet per second

h0 = initial height of the object in feet

h(t) = −16t^2 +160t + 1200

If we look at the graph, we can find the point in which the height becomes maximum.

For this problem,

h = 1600 feet ,

at t = 5 seconds
