Answer:

substitute x = -23 into equation

Step-by-step explanation:

f(x) = 3x2-6x-1

this i interpret as 3 multiplied by 2. So, if you have inputted it wrong , not my fault, so here goes:

f(x) = 6 -6(x) -1

substuting x = -23 ito f(x) , we get

f(-23) = 6 - 6 (-23) -1

f(-23) = 6 + 138 -1

f(-23) = 6 + 137

f(-23) = 143

Ariane borrows $200 on a 2−year loan. She is charged 5% simple interest per year. How much interest is she charged for 2 years?
il63 [147K]

Answer:

Interest charged over two years: $20

Total amount: $220

Step-by-step explanation:

The formula for simple interest is A = P ( 1 + rt ).

A = 200 ( 1 + (0.05 * 2))

A is the total amount ( interest + principle )

A = 220

P is the principle ( initial amount deposited )

P = 200

R refers to rate (in percent)

R = 0.05

T = time period (in years)

T = 2

How do you solve and graph inequalities
Goshia [24]

Well, there can be three different steps.

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
