The answer to this my friend is 5. If you ate one that means there are 10 left. Then if you split 10 in half that equals 5. hope this helps!
Answer: y=-2x+6 where the slope is -2/1 and the y intercept which is b is 6.
Step-by-step explanation:
A) first expand: (2(x+2) - 3(x-1)) x (2(x+2) + 3(x-1))
then distribute: (2x+4-3x+3) x (2x+4+3x-3)
add same terms together and subtract numbers: (-x+7) x (5x-1)
final answer: (-x+7) x (5x+1)
b) same steps as before
I. (5(x-2) - 4(x+3)) x (5(x-2) + 4(x+3))
II. (5x-10-4x-12) x (5x-10+4x+12)
final answer: (x-22) x (9x+2)
Answer:
45.35
Step-by-step explanation:
From the above question, we are told that the annual effective rate = 10% = 0.10
Note also that payment is been made every 2 years
Hence , we apply the formula of effective interest rate for a period of 2 years.
Effective Interest rate(j) = (1 + r)² - 1
= (1 + 0.10)² - 1
= 1.10² - 1
= 1.21
= 0.21
Present value of perpetuality = t/[j × j/(1 + r)²]
Where t = time in years = 2
r = 0.10
= 2/ [0.21 × 0.21/(1 + 0.10)²
= 54.87528
Present value at time t = 0
= 54.87528(1 + r)^-2
= 54.87528(1 + 0.10) ^-2
= 54.87528(1.10)^-2
= 45.35
Therefore, the present value at time (t) is 0 = 45.35
Answer:
275
Step-by-step explanation:
3(8×10)+5(20+2-15)
=3(80)+5(7)
=240+35
=275
