Write the equation of a linear function for which f=(-4)=0 and f=(0)=-2
densk [106]

Answer:

y = -0.5x - 2

Step-by-step explanation:

equation: f(x) = mx + b

f(-4) : -4m + b = 0  ...(1)

f(0):   0m + b = -2            b = -2   ... plug in (1)

-4m - 2 = 0

m = - 1/2 = - 0.5

linear equation: y = -0.5x - 2

What is the interest on Rr 20,000 if the interest rate is 15%?
Basile [38]

Answer: Rr.3,000

Step-by-step explanation:

The interest is the amount that accrues on a principal that was invested or a cost that was incurred.

It is based on a certain interest rate which in this case is 15%.

The principal is Rr. 20,000.

Interest = Principal * Interest rate

= 20,000 * 15%

= Rr.3,000

Are these correct? Please help with #12
BartSMP [9]
All of them seem pretty correct.
Also the answer to 12 is this...

Remove unnecessary parentheses
-6x2/3p^8x3

Then reduce the #’s with the greatest common divisor 3

-6x2p^8

Calculate the product

-12p^8

And that’s your answer:)))
