While David was solving the equation 100x + 300 = 500, he wondered if he could first change the equation to x + 3 = 5. What do you think? a. Solve both equations and verify that they have the same solution. b. What could you do to the equation 100x + 300 = 500 to change it into x + 3 = 5? This problem is a checkpoint for operations with rational numbers

answer: 2/4

step-by-step explanation:

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
