√(x²+13)=2+x
[√(x²+13)]² = (2+x)²
x²+13=4+4x+x²
x²-x²-4x=4-13
-4x=-9
x=-9/-4
x=9/4
To check:
√(x²+13)=√(81/16 +13)=√[(81+208)/16]=√(289/16)=17/4.
2+x=2 + 9/4=(8+9)/4=17/4
Answer:
3.3 years
Step-by-step explanation:
Let the price of the house when it is being sold be = x
The Annual return received from the fund after a year that house is being sold is : A - P
where ;
P = current market price
A = price after one year
A is given by the formula:

where ; P = x
r = 8.5% = 0.085
n = 12
t = 1


A = 1.08839 x
The annual return is A - P = 1.08839 x - x
= 0.08839x
However, the house should be sold when this return is equivalent to the annual increase in value of the house
∴ 0.08839x = 31250

Thus , the current price (x) = $353546.78
Profit till that time = Current price - Initial Price
= (353546.78- 250000)$
= $103546.78
The time taken for this much profit to accumulate = 
= 
= 3.3135
≅ 3.3 years ( to one decimal place)
Answer:
=15.4
Step-by-step explanation:
6^2+(3.4)-24 = 36+3.4−24
36+3.4−24
39.4−24
=15.4
The value of z is zero
Step-by-step explanation:
The slope is the steepness of the line.
The formula for slope is given by:

Here
(x1,y1) = (1,z)
(x2,y2) = (2,8)
So,

The value of z is zero
