-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
The correct answer is: -tan 32degrees
If Connie and her two friends are completing the relay, this means that there are three people.
If they each rode an equal part of the race this means that we must divide the 10 miles (the distance ridden) by 3 (the number of racers).
As a fraction this equals 3 and 1/3 and in a decimal this equals approximately 3.33
300? Sorry if I’m wrong but that’s what i would’ve put
Answer:
a.
b.
Step-by-step explanation:
We are given that
a.Substitute z=0
...(1)
..(2)
Subtract equation (1) from equation (2)
Substitute y=0 in equation(1)
The point (6,0,0) lie on a line.
Let 
Therefore, the vector 
Line is parallel to vector a' and passing through the point (6,0,0).
The parametric equation is given by
Using the formula
The parametric equation is given by
Angle between two plane
and 
Using the formula
