Answer:
-1
Step-by-step explanation:
Any variable without a visible coefficient means it has a coefficient of 1. Since it's negated, the coefficient is -1.
Answer:
a) (11/7, 9/7)
b) There's no point of intersection
Step-by-step explanation:
a) x - 2y + 1 = 0
2x + 3y - 7 = 0
To find the point of intersection, we need to solve the system of equations and the result will be the point of intersection (x,y)

Now we substitute x in the second equation:

Now we substitute y in our first equation.
.
The point of intersection is (11/7, 9/7)
b) x -2y +11 =0
-x + 2y - 13 =0
We are going to follow the same procedure:


Since this system of equations doesn't have a solution, the system has no point of intersection.
Answer:400 meters
Step-by-step explanation:
2000/5=400
Answer:
GCF would be 10
Step-by-step explanation:
GCF, aka <em>the greatest common factor</em> is the biggest number that can be multiplied to get that number. for example, in this situation it would be 1- because 10 can be multiplied to get any of those numbers. 1 x 10 = 10 ; 2 x 10 =20 ; 4 x 10 = 40. hope this helped!!
Answer:
9.93 liter approximately 10 liter
Step-by-step explanation:
3 days = 3/2 quart
3 week = 3/2/3 × 21 quarts
= 1/2×21
=21/2 quarts
now
1 quart = 0.946 liter
21/2 quart = 0.946×21/2 liter
21/2 quart = 9.93 liter
