Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.
So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.
You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.
You get 3/1 × 1/1 = 3
It equals to 3
Then, 4(2.6) = 4 × 2.6 = 10.4
2(-3) = +2 × (-3) = -6
When you multiply a positive number for a negative one, you'll always get a negative number.
Sum all the results.
3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4
Final answer: -13,4
Answer:
C. Both Functions Have a y-intercept of -2
Step-by-step explanation:
In Function F it shows us that it has a y-intercept of -2, and in the equation of Function G it shows us that you would subtract 2 out of what the initial value would be:
(3 x 0 = 0)
0 - 2 would be -2 so it would have a y-intercept of -2.
Answer:
( 8 , - 8) => x² - 55 = 9
( 4 , - 4) => 2x² - 32 = 0
(5 , - 5) => 4x² - 100 = 0
(11 , - 11) => x² - 140 = -19
( 3, - 3) => 2x² - 18 = 0
Step-by-step explanation:
1)
x = ( 4 , - 4)
2)
x = ( 5 , - 5 )
3)
x= ( 8 , - 8)
4)
x = ( 11 , -11)
5)
x = ( 3 , - 3)
Answer:
See below in bold.
Step-by-step explanation:
Total = A(1 + r/n)^nt where A = initial amount , t = number of years, r = the rate (as a decimal fraction) and n = number of payments a year. So:
Total after 1 year = 8000(1 + 0.09/2) ^ 1*2
= RS 8736.20.
Compound interest = RS 736.20
its 1200 i think i work it out but i could have done it wrong
