F(5)=4(5)-11
f(5)=20-11
f(5)=9
This is all I have, I don't really understand that sry
<span>Part A:
The plant is 11.26 cm tall at the end. How many days?
We use 8(1.05)^n=(height of plant)=11.26
To find ‘n’ divide by 8: 8(1.05)^n=11.26 〖1.05〗^n=1.4075
</span>Hope this helps :)
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
Absolute value tells how many spaces the number is from 0. And opposite numbers are negative numbers on the left side of 0.
Answer:
-19 y^2 + 18 x y + 13 x^2
Step-by-step explanation:
Simplify the following:
16 x^2 + 15 x y - 19 y^2 - (3 x^2 - 3 x y)
Factor 3 x out of 3 x^2 - 3 x y:
16 x^2 + 15 x y - 19 y^2 - 3 x (x - y)
-3 x (x - y) = 3 x y - 3 x^2:
16 x^2 + 15 x y - 19 y^2 + 3 x y - 3 x^2
Grouping like terms, 16 x^2 + 15 x y - 19 y^2 - 3 x^2 + 3 x y = -19 y^2 + (15 x y + 3 x y) + (16 x^2 - 3 x^2):
-19 y^2 + (15 x y + 3 x y) + (16 x^2 - 3 x^2)
x y 15 + x y 3 = 18 x y:
-19 y^2 + 18 x y + (16 x^2 - 3 x^2)
16 x^2 - 3 x^2 = 13 x^2:
Answer: -19 y^2 + 18 x y + 13 x^2
