Answer:

y=5x+4

Step-by-step explanation:

Hi!

They want you to use the slope-intercept form

slope-intercept form is y=mx+b

m=slope

b=y-intercept

So, since m=5 and b=4 you just replace the values in y=mx+b

Therefore, y=5x+4

I hope this helps!!! :)

PLEASE HELP ASAP AND THANKS Find x

Answer:

The value of x is 2.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denorminator the same :

$\frac{x}{x - 2} + \frac{1}{5}$

$= \frac{5x}{5(x - 2)} + \frac{x - 2}{5(x - 2)}$

$= \frac{5x + x - 2}{5(x - 2)}$

$= \frac{6x - 2}{5(x - 2)}$

Then you have to do cross multiplication :

$\frac{6x - 2}{5(x - 2)} = \frac{2}{x - 2}$

$(6x - 2)(x - 2) = 5(2)(x - 2)$

$6 {x}^{2} - 12x - 2x + 4 = 10x - 20$

$6 {x}^{2} - 14x + 4 = 10x - 20$

$6 {x}^{2} - 14x + 4 - 10x + 20 = 0$

$6 {x}^{2} - 24x + 24 = 0$

$6( {x}^{2} - 4x + 4) = 0$

${x}^{2} - 4x + 4 = 0$

${x}^{2} - 2x - 2x + 4 = 0$

$x(x - 2) - 2(x - 2) = 0$

$(x - 2)(x - 2) = 0$

$x = 2$

Answer:

3. $\displaystyle y = \frac{2}{5}x + 1\frac{2}{5}$

2. $\displaystyle y = -\frac{5}{7}x + 2$

1. $\displaystyle y = -2x + 4$

Step-by-step explanation:

3. 2x - 5y = −7

- 2x - 2x

__________

$\displaystyle \frac{-5y}{-5} = \frac{-2x - 7}{-5} \\ \\ y = \frac{2}{5}x + 1\frac{2}{5}$

2. 5x + 7y = 14

- 5x - 5x

__________

$\displaystyle \frac{7y}{7} = \frac{-5x + 14}{7} \\ \\ y = -\frac{5}{7}x + 2$

1. 6x + 3y = 12

- 6x - 6x

__________

$\displaystyle \frac{3y}{3} = \frac{-6x + 12}{3} \\ \\ y = -2x + 4$

I am joyous to assist you anytime.

Hey guys ( or gals ) I have no idea what to do please help me.

Answer:

Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.

You would have to find a GCF (greatest common factor) and multiply it out of the radical.

ex.

$\sqrt{6}$ = 2 x 2 x 2

when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2

2 $\sqrt{2\\}$

so $\sqrt{6}$ would be closest to the positive 2 on the number line and 2 notches.

$\sqrt{11}$

is an irrational number, so it might fall into 3.3 if turned into a decimal.
