20y-10x=5 in slope intercept form can you explain the steps
Studentka2010 [4]

Given:

The equation is

20y-10x+5

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

y=mx+b

Where, m is slope and b is the y-intercept.

We have,

20y-10x=5

We need to isolate y. Add 10x on both sides.

20y-10x+10x=5+10x

20y=5+10x

Divide both sides by 20.

\dfrac{20y}{20}=\dfrac{5+10x}{20}

y=\dfrac{5}{20}+\dfrac{10x}{20}

y=\dfrac{1}{4}+\dfrac{x}{2}

y=\dfrac{1}{2}x+\dfrac{1}{4}

Therefore, the slope intercept form of the given equation is y=\dfrac{1}{2}x+\dfrac{1}{4}.

how do I figure out the weight loss of tina? she lost 3 pounds on the first week of her diet. she gained a pound on the second w
hram777 [196]
1st week - Lost 3 pounds = +3 
2nd week - Gained 1 pound = -1    
3+13 = + 22       

So 22+3 = 25                 25-1 = 24 

So Tina lost 24 pounds in 13 weeks.

Karolina [17]
To start off, Chang has already saved $45. $125 - $45 = $80. Therefore, he owes $80. $80 ÷ 7 = 11.4285714286, so he needs to work 12 full hours to pay for his trip.
