Why is isolating the y-variable to graph is important
dusya [7]

Answer:

It is the easiest way to graph an equation.

Step-by-step explanation:

Isolating the y variable is also slope-intercept form.

Slope intercept form is the easiest form to use when graphing.

y = mx + b

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

it makes it way easier to graph an equation when it is in slope intercept form.


I hope that helps! =)

Please Explain/Show your work!
Zigmanuir [339]

Answer:

They are both proportional.

Tank A = .00375 minutes/gallon

Tank B = 2/600 or ~0.003 minutes/gallon

Step-by-step explanation:

They are both proportional because as time increases, the amount of gallons increases.

Tank A unit rate

Tank B unit rate

Rate = rise / run

Choose points on the graph that has definite points.

Tank A = (1.5 mins - 0.75 mins) / 200 gallons

Tank A = .00375 minutes/gallon

Tank B = (2 mins - 0 mins) / 600 gallons

Tank B = 2/600 or .003 minutes/gallon

Step-by-step explanation:

\angle AOB and \angle BOC are linear pair angles.

\therefore m\angle AOB + m\angle BOC = 180° \\  \therefore  \: 3x + 124 \degree + 6x + 29 \degree  = 180° \\  \therefore  \: 9x  + 153 \degree  = 180°  \\ \therefore  \: 9x  = 180°  - 153 \degree   \\ \therefore  \: 9x  = 27 \degree   \\ \therefore  \:x =  \frac{27 \degree }{9}  \\  \huge \pink{ \boxed{\therefore  \:x =3 \degree }} \\  \\  \because \: m\angle BOC =6x + 29 \degree   \\ \therefore \: m\angle BOC =6 \times3 \degree + 29 \degree   \\ \therefore \: m\angle BOC = 18\degree + 29 \degree    \\ \\   \huge \red{ \boxed{\therefore \: m\angle BOC = 47 \degree   }}

How does algebra affect how people can learn from each other?
pantera1 [17]

Algebra is Faster And Better Than “Basic” Math

Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
