Answer 1

Answer: $2v^2+12v-27=9v\ \ \ \ /-9v\n\n2v^2+3v-27=0\n\na=2;\ b=3;\ c=-27\n\n\Delta=b^2-4ac\n\n\Delta=3^2-4\cdot2\cdot(-27)=9+216=225\n\nv_1=(-b-\sqrt\Delta)/(2a);\ v_2=(-b+\sqrt\Delta)/(2a)\n\nv_1=(-3-√(225))/(2\cdot2)=(-3-15)/(4)=(-18)/(4)=-4(1)/(2)\n\nv_2=(-3+15)/(2\cdot2)=(12)/(4)=3$

$2v^2+3v-27=0\n\n2(v+4(1)/(2))(v-3)=0\n\nAnswer:v=-4(1)/(2)\ \vee\ v=3.$

Jamal has a plan to save money for a trip. Today, Jamal deposits $10.00 into the savings account. Each week, Jamal will add $5.00 to the amount that is deposited into the savings account. The table below shows the relationship between the number of weeks and how much money, in dollars, Jamal deposits into the savings account.Let f(x)represent the amount of money Jamal deposits into his savings account at the end of x weeks. Based on the table, what is f(10)?

Answer:

y = 5x + 10

Step-by-step explanation:

using the formula y = mx + b you can easily find the answer.

where

m = the rate of change

b = constant

x = the independent variable

Since he has the initial $10.00 added to the account, we know that is the constant since he won’t be adding that anymore.

Since he will be adding $5.00 to the account every month we know that this is the rate of change.

the variable x will change depending on the number of months passed.

Therefore we can create the equation:

y = 5x + 10
