Six times a number is 45 greater than the the product of the number and -3. Find the number.

blagie [28]

Let us try to formulate the expressions one by one.

let the number be x.

Step 1:

six time the number is 6*x = 6x

Step 2:

product of the number and -3 is -3x

Step 3:

now let us make equation for it:

$6x = -3x +45$

adding 3x on the left side,

$6x+3x = 45$

$9x = 45$

dividing right side by 9

x=45/9 = 5

So the number is x=5

Put the following equation of a line into slope-intercept form, simplifying all fractions.

Inessa [10]

Answer:

$y=\frac{3}{5} x-3$

Step-by-step explanation:

Slope-intercept form: y = mx+ b

m = slope

b = y-intercept

Rearrange the equation:

$-20y=-12x+60$

Divide each side by -20:

$\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}$

$y=\frac{3}{5} x-3$

$y=\frac{3}{5} x-3$ is your simplified, slope-intercept form equation.
