Determine by inspection whether the lines in each system below intersect, coincide, or are parallel. Do not actually solve the systems. Justify your reasons. (y=MX+B) C.) y=13x+2 D.) y=13x-2

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Plot a point at the y-intercept of the following function on the provided graph. 3y=-5x+7 20 points

The scatter plot shows the number of animal cells clara examined in a laboratory in different months: plot ordered pairs 1, 20 and 2, 60 and 3,100 and 4, 140 and 5, 180 what is the approximate predicted number of animal cells clara examined in the 9th month?
