Alexis opened a savings account with a $120 deposit. Each week she will put $20 into the account. The equation that gives the total amount t in her account is t 120 20w, where w is the number of weeks since she opened the account. How much money will Alexis have in her savings account after 5 weeks?

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Step-by-step explanation:

The equation that gives the total amount t in her account is t=120+20w, where w is the number of weeks since she opened the account.

To calculate the amount of money Alexis will have in her savings account after 5 weeks, you replace the number of weeks w since she opened the account by 5:

t=120+20*5

Solving, you get:

t=120+100

t=220

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
