<h3>
Therefore they are perpendicular.</h3>
Step-by-step explanation:
A equation of line is
y =mx +c
Here the slope of the line is m.
Given equations are
x - 2y = 18
⇔-2y = -x +18
............(1)
and 2x + y = 6
⇔y = -2x +6 ............(2)
Therefore the slope of equation (1) is
= 
Therefore the slope of equation (2) is
= -2
If two lines are perpendicular, when we multiply their slope we get -1.
therefore,
=. (-2) = -1
Therefore they are perpendicular.
3 eggs for brownies, 2 eggs for cookies.
Because the total count went up 2 for one more batch of cookies, you know that 1C(ookies) = 2 eggs
3C = 6 eggs
15 - 6 = 9 eggs
3B(rownies) = 9 eggs
1B = 3 eggs
Answer:
100 grams.
Step-by-step explanation:
600-(10*50). You're subtracting the weight of 10 mangoes (50 grams for each mango) from 600 grams, which will give you the weight of the basket.
Slope is change in y over change in x.
Change in y is -9
Change in x is +12
So -9/12 or -2/3
Answer -2/3
