Compare Look at these equations. Do you think they are all linear equations? Can they
Georgia [21]

Answer:

Yes they can all be written in y = mx + b. You just have to move the terms around.

Step-by-step explanation:

y = 2x -3, this is already in slope-intercept form

Now, y - 2 = x + 2: We can add 2 on both sides to cancel out the one on the left side:

y - 2 = x + 2

y - 2 + 2 = x + + 2

y = x + 4 <-- This is in y = mx + b form

Now the last one, 3x = 9 + 3y

We can first divide all terms by 3,

3x = 9 + 3y

/3     /3   /3

x = 3 + y: Then we can subtract 3 from both sides:

x - 3 = 3 + y - 3

x - 3 = y

These are all linear equations because none of the x's have bigger powers than 1. x^2 is a quadratic equation and x^3 is cubic equation.

18 of the students in history class past a history test if the students are 75% of all the students in the class how many studen
BabaBlast [244]

Answer:

24 people in the history class.

Step-by-step explanation:

Let the total number of people in the class = x. I do this rather a long way because people often have trouble dealing with the division of fractions.

Equation

75/100 * x = 18              Multiply by 100

Solution

75x = 18*100

75x = 1800                     Divide by 75

x = 1800/75

x  = 24

There are 24 people in the class
