Answer:
4xy + 11x
Step-by-step explanation:
6xy - 2xy + 13x - 5x ( taking like terms together )
4xy + 11x
Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x
If there are 3x-2 trees planted in each row, and we have a total of 24x-16 trees, this means that the number of trees multiply the number of rows will give us the answer of 24x-16
let r=number of rows
(3x-2)*r=24x-16
to find r we will divide both side by 3x-2
r=<u>24x-16
</u> 3x-2
<u>
</u>we see that 8 is a common factor for the numerator
r= 8(3x-2)/3x-2=8
we have 8 rows
