Answer:
26 units
Step-by-step explanation:
Using the formula above,
distance between (-10, 3) and (0, 27)
= 26 units
Answer:
4x + y = 1
Step-by-step explanation:
Start with the familiar format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
With a slope of -4, we can write:
y = -4x + b
We need to find a value for b that forces the line through point (1,-3). This is done by entering this point in the equation and solving for b:
y = -4x + b
-3 = -4*(1) + b
b = 1
The equation is y = -4x + 1, This can be rewritten as:
4x + y = 1
Se attached graph.
0.2x + 0.7(50) = 0.4(x + 50)
0.2x + 35 = 0.4x + 20
35 = 0.2x + 20
15 = 0.2x
75 liters = x
