In which quadrant is the point(-5, 2/3) located?________ Identify the coordinate of the points: By showing the resulting identity or contradiction, determine, yes or no, if the given point is a solution of the equation: -3a +4b = 13 (3, -1) (-2, 2) (0, 13/4) In which quadrant is the point: (35, -18) located? ______ Plot (and label on the graph above, the points: B(-3, 2) C: (4, 5) D:(3, -4) E: (-5, 2) Kitchen Design. Kitchen designers located? recommend that a refrigerator be selected on the basis of the number of people n in the household. The Identify the coordinates of the points: appropriate size S, in cubic feet, is given by S = 3/2 n +13 Determine the recommended size of a refrigerator if there are 7 people in the household.

Solution

Only one mistake that i could spot was in 3A, so here goes...

You got the answer as -14, when infact it was -13 on the left

Here it is

3a)
(3 , -1)
-3a + 4b = 13

-3(3) + 4(-1) = 13

-9 - 4 =13

-13 = 13

Not true

So, not a solution

All the rest were all correct

Well done!
