The time taken by Jill and Cheryl to double their money is 12 years and 18 years respectively.
<h3>What is Algebra?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
Jill invested $500 in an account with a compound interest rate of 6%.
Cheryl invests $600 in an account with a compound interest rate of 4%.
The number of years each doubles their money. Using the relation of 72.

where r is the interest rate and t be the time
The time for the Jill will be

The time for the Cheryl will be

Answer:
275.
Step-by-step explanation:
The gradient of the graph is 70/2 = 35 and it passes through the origin so we can write its equation as
y = 35x.
The gradient of the function represented by the the table is
(240-180) / (4-3) = 60
Ehen x = 3 y = 180 so when x = 0 y = 180 - 60 - 60 - 60 = 0 and the equation of this function is
y = 60x.
For the first equation when x = 11, y = 35*11 = 385.
For the second it is 60 * 11 = 660
So our answer is 660 - 385
= 275
Answer:
7
Step-by-step explanation:
(f + g)(n) = f(n) + g(n) = n - 3 + n - 2 = 2n - 5 , thus
(f + g)(6) = 2(6) - 5 = 12 - 5 = 7
<u>Answer:</u>
Supplement of 84° is 96°
Complement of 54° is 36°
<u>Step-by-step explanation:</u>
1<u>) A supplementary angle is two angles that add up to 180°</u>
so to find the supplement of 84° ⇒ 180°- 84° = 96°
2) <u>A complementary angle is two angles that add up to 90°</u>
so to find the complement of 54° ⇒ 90°- 54° = 36°
<u>Answer:</u>
the function f(x) = 2x - 1 indicates:
a downward shift of 1 unit
as the y-intercept: (0, -1)
