Students were asked to choose their favorite food. If 4/10 the students chose pizza and 4/10 chose tacos,
what fraction chose either pizza or tacos?

4/5

Step-by-step explanation:

Simply add the two fractions together

4/10 + 4/10 = 8/10

Then simplify

8/10 = 4/5

4/5 students chose either pizza or tacos

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
