1 2/5m - 3/5 ( 2/5m + 1 )
Hunter-Best [27]

Answer:

1 4/25 - 3/5, or 29/25 - 3/5, or \frac{(29m - 15)}{25}

it doesn't really matter they all mean the same

Step-by-step explanation:

1 2/5m - 3/5(2/5m + 1)

multiply first

1 2/5m - 6/25m - 3/5

multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.

1 10/25m - 6/25m - 3/5

add/subtract

1 4/25m - 3/5

Write an equation of the line below.
Dafna11 [192]

Answer:

\large\boxed{y=4x+3}

Step-by-step explanation:

The slope-intercept form of an equation of aline:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfraxc{y_2-y_1}{x_2-x_1}

From the graph we have the points:

(-2, -5)

y-intercept (0, 3) → <em>b = 3</em>

Calculate the slope:

m=\dfrac{3-(-5)}{0-(-2)}=\dfrac{8}{2}=4

Put the value of the slope and the y-intercept to the equation of a line:

y=4x+3
