Answer:
solution is (-2,4)
Step-by-step explanation:
Let’s graph both equations.
solve for y
Make a table to graph the equation
x y=-x+2
0 y=2
1 y=1
Graph the points (0,2) and (1,1) . then extend the line that connects two points
x y=(1/2)x+5
0 y=5
2 y=6
Graph the points (0,5) and (2,6) . then extend the line that connects two points
The graph is attached below
Both lies intersects at (-2,4)
Answer:
y=1x+-1
Step-by-step explanation:
y=mx+b
m=slope which is 1/1 because it is rise over run (rising 1, running 1)
b=y-intercept form which is -1 because that is where the line meets the y axis
Answer: 10 : 4 : 3
Step-by-step explanation:
According to the question,
For a medicine,
Water used = 1 liter = 1000 ml
Sucrose used = 400 ml
And, Saline used = 300 ml
Thus, the ratio of water, sucrose and saline water for making a medicine,
= 1000 : 400 : 300
= 10 : 4 : 3
Which is the required simplest form of the ratio of water, sucrose and saline water.
