Answer: A) The x-intercept decreases.
Step-by-step explanation:
Hi, for the function f(x) = mx + b, if the value of b decreases, but the value of m remains the same, The x-intercept decreases.
For example
For b=2, m =1 and x =0 (since the y-value of a linear equation when it crosses the x-axis is 0 )
f(x) =0(1)+2 =2 (x-intercept)
For b= 1 (b decrease)
,m =1 and x =0
F(x) = 0(1) +1 = 1 (x_intercept also decreases)
So, the correct option is A) The x-intercept decreases.
Feel free to ask for more if needed or if you did not understand something.
2.80 is more than 2, i would round it.
So sorry if this is wrong :(
Based on the given above, the correct answer would be <span>x-30y=100 and 10y=x-20, the first option.
So how do we know that this is the correct option. So, let us check
0.01x - 0.3y = 1 <<multiply both sides by 100 (since there is 2 decimal places after the decimal point
The result for this would be x - 30y = 100 (So this is correct)
Next,
y = 0.1x -2 << multiply both sides by 10 since there are only 2 decimals places after the decimal point
The result would be 10y = x - 20 (So this is correct)
Hope that answer helps</span>
