2. Fran invested $700 in two funds that pay 6% and 5.5% annual interest. Fran’s combined annual interest is $40.50. How much of the $700 was invested in each fund? 3. Label the variables. Let x represent: Let y represent:
4. We know that Fran invested a total of $700, i. e. “total amount invested = 700”.
Translate this statement into an algebraic equation: Now translate the statement “total interest = 40.50” into an algebraic equation. (Keep in mind that interest comes from interest rate times amount invested) 5. Write the two equations below and solve the system. 6. Use your solution to the system to answer the question you wrote in #1. (In English!) Fran invested

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

it's d
