The solution of given system of linear equation is:
x=3 and y=10
Step-by-step explanation:
Given equations are:
-8x+5y=26 Eqn 1
9x-3y=-3 Eqn 2
Multiplying equation 1 by 9
-72x+45y=234 Eqn 3
Multiplying Equation 2 by 8
72x-24y=-24 Eqn 4
Adding Eqn 3 and 4

Dividing both sides by 21

Putting y=10 in equation 1

Subtracting 50 from both sides

Dividing both sides by -8

Hence the solution of given system of linear equation is:
x=3 and y=10

Answer:i.a)-x-3 b)5x+5 ii.b)-6x2-11x-4
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
The points on the graph :
(4, 180) ; (7, 135)
x1 = 4 ; y1 = 180
x2 = 7 ; y2 = 315
The number of soda bottles the machine can make in a minute is the gradient or slope :
Gradient = change in y / change in x
Gradient = (y2 - y1) / (x2 - x1)
Gradient = (315 - 180) / (7 - 4)
Gradient = 135 / 3
Gradient = 45
Hence, the machine can make 45 soda bottles in a minute.
