Through (-1,-1), slope of 4 what is the standard form equation of the line through the given point with a given slope

Vinvika [58]

Answer:

The equation of the line is -4x + y = 3

Step-by-step explanation:

Since we have the slope, we can use it and either point in point-slope form and solve for the standard form of the equation.

y - y1 = m(x - x1)

y - -1 = 4(x - -1)

y + 1 = 4(x + 1)

y + 1 = 4x + 4

-4x + y + 1 = 4

-4x + y = 3

Write an equation to represent the number puzzle. Use x as the

k0ka [10]

<h3>The equation is:</h3><h3> $x^2 - 7x + 12 = 0$ </h3><h3>The number is 3 or 4</h3><h3><em><u>Solution:</u></em></h3>

Given that,

7 added to the square of a number is equal to 7 times the number, minus 5

Let "x" be the unknown number

From given,

7 added to square of x = 7 times the x minus, 5

$7 + x^2 = 7x - 5$

Solve the above equation

$x^2 -7x +7+5 = 0\\\\x^2 - 7x + 12 = 0$

Split the middle term

$x^2 -3x - 4x + 12 = 0\\\\Group\ the\ expressions\\\\(x^2-3x) -(4x - 12) = 0\\\\Take\ the\ common\ factor\ out\\\\x(x -3) -4(x -3) = 0\\\\(x-3)(x-4) = 0$

We have two solutions

x - 3 = 0

x = 3

And

x - 4 = 0

x = 4

Thus number is 3 or 4

I need help on this

Viefleur [7K]

Answer:

See below

Step-by-step explanation:

Which is the closest to 6

$\sqrt{34}$

$\sqrt{39\\$

$\sqrt{35$

or $\sqrt{38}$

So, find the square root of each ( I suggest using a calculator)

$\sqrt{34} = 5.83\\\sqrt{39} = 6.24\\\sqrt{35} = 5.91 \\\sqrt{38} = 6.16$

Which is closest? Let's see.

6 - 5.83 = 0.17

6.24 - 6 = 0.24

6 - 5.91 = 0.09

6.16 - 6 = 0.16

Find the smallest #

0.09 is the smallest, so 5.91 is the closest. Square the #, we get $\sqrt{35}$

Hope this helps! =D
