Given:
For every 3 seeds Lara planted, only 2 seeds grew.
Altogether, 12 seeds grew.
To find:
The number of total seeds planted by Lara.
Solution:
It is given that for every 3 seeds Lara planted, only 2 seeds grew. It means the ratio of total seeds planted to seeds grew is 3:2.
Altogether, 12 seeds grew.
Let x be the number of total seeds planted by Lara. Then,




Therefore, the total number of seeds planter by Lara is 18.
Answer:
Option A:
is the correct answer.
Step-by-step explanation:
Given that:
Slope of the line = 
Let,
m be the slope of the line perpendicular to the line with slope 
We know that,
The product of slopes of two perpendicular lines is equals to -1.
Therefore,

Multiplying both sides by 

m = 
is the slope of the line perpendicular to the line having slope
Hence,
Option A:
is the correct answer.
Answer:
dy/dx = 
Step-by-step explanation:
-y + 2x²- x = -5y³
2x² - x = y - 5y³
4x - 1 = dy/dx - 15y².dy/dx
dy/dx(1 - 15y²) = 4x - 1
dy/dx = 
You would need one because you arent yet to 20 so it takes one tenth for example;
1.7 or 7/10
Thats my guess tho man if it is more complicated than that, SORRRYYYY
As tgose lines are parallel then,
a = 140° ( by alternate interior angles)
then,
tha angle just below "a" on the other paralle line would also be 140° by corresponding angles,
using exterior angle property of triangle
66° + b = 140°
b = 140° -66
= 74°
