Answer:
slope = 1/7
Step-by-step explanation:
7x+y=9 you should be in slope int form--> y=-7x+9
then the line is perpendicular so
the slope is 1/7
If a function can be written in y = mx + b form, it is linear.
The function given:
Taking "5" to the right hand side, we get:
This is in the form y = mx + b, with m = 5 and b = 5.
This is a linear function.
Answer:
Amount of B used = 276.6 millimeters
Step-by-step explanation:
A = A millimeters
B = A + 400 millimeters
Hence
Taking an overall balance
(0.16 x A) + (0.2)(A+400) = 476
0.16A + 0.2A + 80 = 476
A = 1100 millimeters
B = 1100 + 400 = 1500 millimeters
Hence using direct proportion
2600 --------------------476
1500 ---------------------X
X = 276.61538
Amount of B used = 276.6 millimeters
