I know the answer to a but not to b please help.. will give brainliest

Answer for b- At 10 weeks they will both have $300 in their bank account.

Step-by-step explanation:

Since Olivia starts with $200 in her savings account and adds $10 per week, we can plug the equation y=200+10x into the calculator (use y= button). For Evelyn's equation, we can plug in 25x+50. Now press 2nd, graph on your calculator and scroll until the two columns on the right are equal. (Picture for help)

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
