Grouping,
looking at the coefficients (2,-7,-4, and 14)
you notice that 2,-4, and 14 are all factors of 2,
however you also notice that -7 and 14 arefactors of 7, so you want to group the terms containing -7 and 14 up (and 2 and -4 together)

so rearranging stuff
2x^3 -4x -7x^2+14

grouping
(2x^3-4x) + (-7x^2+14)

factoring stuff, (reverse distribution process)
notice you can factor out a 2x from the first group, and a -7 from the 2nd group, hence you will get

2x(x^2-2) -7(x^2-2)

you can factor out the (x^2-2) from both terms, hence you are left with

(2x-7)(x^2-2)

If you apply the changes below to the absolute value parent function, f(x) = |Xl,

TiliK225 [7]

Answer:

• Shift 5 units to the left >>> f(x) = |x+5|

• Shift 4 units down >>> f(x) = |x| - 4

Step-by-step explanation:

If we have the parent function:

f(x) = |x|

<u>For horizontal translations:</u>

|x-a| means horizontally translated a units right
|x+a| means horizontally translated a units left

<u>For Vertical translation:</u>

|x| + b means vertically translated b units up
|x| - b means vertically translated b units down

From the translation rules, we can say:

Shift 5 units left would be:

|x+5|

and

Shift 4 units down would be:

|x| - 4

Harry owes the bank money. To repay his debt, he paid \$150$150dollar sign, 150 back to the bank each month. After 101010 months

Sonja [21]

$8,400
Explanation:
Amount repaid each month = $150
Number of Periods for which amount was paid = 10 months
Amount left after 10 months payment = $6900
The total amount paid = $150 × 10 = $1500
Amount left = $6900
Total debt amount:
(Total Amount left + total amount paid )
$(6900 + 1500)

So me 3 ways you get to 100

In-s [12.5K]

10 x 10 = 100
20 + 20 + 20 + 20 +20 = 100
4 x 25 = 100

Yvette is considering taking out a loan with a principal of $16,200 from one of two banks. Bank F charges an interest rate of 5.

umka21 [38]

Hi there
First find the monthly payment of each offer to see which monthly payment is lower
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value
PMT monthly payment
R interest rate
K compounded monthly 12
N time
Solve the formula for PMT
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]

Bank F
PMT=16,200÷((1−(1+0.057÷12)^(
−12×8))÷(0.057÷12))
=210.53

Bank G
PMT=16,200÷((1−(1+0.062÷12)^(
−12×7))÷(0.062÷12))
=238.21

From the above the monthly payment of bank f is lower than the bank g
And since the lifetime of bank g is lower than bank f the answer is
b. Yvette should choose Bank F’s loan if she cares more about lower monthly payments, and she should choose Bank G’s loan if she cares more about the lowest lifetime cost.

Good luck!
