Betty has a checking account and a non-interest bearing savings account. The function C(x), shown below, represents her checking

account balance, where x is the number of months. The function S(x), shown below, represents her saving account balance.

C(x) = -2401 - 140 + 1,400

S(s) = 4503 + 100

Which function represents Betty's total account balance. T(x)?

T(x) or total account balance = C(x) + S(x)

Step-by-step explanation:

where = C(x) = -2401 - 140 + 1,400  

and

S(x) = 4503 + 100

This implies that:

C(x) = 3,661

S(x) = 4,603

Therefore, T(x) 3,661 + 4,603 = 8,264

T(x) is the total account balance or the addition of the balances of checking and saving accounts.

C(x) is the checking account balance.

S(x) is the saving account balance.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
