Answer:
The unknown number is greater than equal to 12
Step-by-step explanation:
If we need to solve the equation will be
let the number be x
4+3x 40
3x 40-4
3x 36
x 36/3
x 12
This means x is greater or equal to 12
Given the equation y = 3x + 5 , write the equation of a new line that would have the same y-intercept but would be steeper.
1 answer:
Answer: y = 4x + 5
Step-by-step explanation:
The general equation of a line is y = mx + d ,
m = slope
d indicates the y-intercept, when x=0 , Y=5 => (0,5)
In the given line m = 3 , so that is the slope.
This slope has an angle = arctan(3) = 71.56º
If we need a steeper line, we have to increase m,
By example y = 4x + 5 , would have the same y-intercept but would be steeper.
This new line has a greater slope, with an angle = arctan (4) = 75.96º
