Randa ate 3/8 of a pizza, and Marvin ate 1/4 of the same pizza. What fraction of the pizza did Randa and Marvin eat?

5/8 of the pizza

Step-by-step explanation:

1/4 is equal to 2/8, so if you add 1/4 and 3/8, it equals 5/8, which is the total fraction of the pizza eaten

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
