What is -4x-5=6-11x? Please show work

First, you would add 11x to both sides, because you are trying to separate the variable pieces and the constants (integers).

If performed correctly, you would get the equation
7x-5=6

Then, you would add 5 to both sides, to get the 7x alone.

This results in the equation 7x=11

Then, to get x alone, without a coefficient, you would need to divide both sides by 7.

x=11/7

3. Jalen is a lifeguard at a public swimming pool and is planning to string

m_a_m_a [10]

Answer:

$Flag = 55.90m$

Step-by-step explanation:

Given

$Length = 50m$

$Width = 25m$

Required

Determine the length of the flag

Because the flag crosses through opposite diagonals of the pool. Its length is the length of the diagonal of the pool.

This is calculated using Pythagoras theorem.

$Flag^2 = Length^2 + Width^2$

Substitute values for Length and Width

$Flag^2 = 50^2 + 25^2$

$Flag^2 = 2500 + 625$

$Flag^2 = 3125$

Take positive square root of both sides

$Flag = \sqrt{3125$

$Flag = 55.90m$

<em>Hence, the length of the flag is approximately 55.90m</em>

What is the equation for the points (-2,3) (1,9) on a graph

Over [174]

9514 1404 393

Answer:

y -9 = 2(x -1) . . . point-slope form
y = 2x +7 . . . . slope-intercept form
2x -y = -7 . . . . standard form

Step-by-step explanation:

Perhaps you want the equation of the line that goes through these two points.

The slope of the line can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

m = (9 -3)/(1 -(-2)) = 6/3 = 2

We can use one of the points to write the equation in point-slope form:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

For slope 2 and point (1, 9) the equation is ...

y -9 = 2(x -1) . . . . equation in point-slope form

__

We can eliminate parentheses and get y by itself to put the equation into slope-intercept form.

y -9 = 2x -2

y = 2x +7 . . . . . . equation in slope-intercept form

__

With a little further rearranging, we can put this into standard form. We can get that by adding -7-y to both sides of the equation.

2x -y = -7 . . . . . equation in standard form
