Answer:
x = 10.5
Step-by-step explanation:
3x - 30 = 1.5
3x = 31.5
x = 10.5
Yes, it is possible, Rhianna is right.
The x-intercepts are only points where the functions touchs the x-axis, this is the y-coordinate of the function is 0.
As long as the domain contains this point, there are infinite function with the same domain and range that satisfy the condition that the x-intercepts are equal.
Examples:
y = x + 5
y = 2x + 10
y = 3x + 15
For those three functions, when x = -5, y =0. Those the x-intercept is (-5,0).
Alright lets look at this problem the first step is to find out how far down she went in 4.5 minutes. so 7*4.5=31.5 ft next what you have to do is add 31.5 ft to 140 ft which is 171.5 ft next you need to subtract 112.2 ft from 171.5 ft which means that the divers current depth must be 59.3 Ft.
Plug in 0 for x in the equation:
y=5x-3
y=5(0)-3
y=0-3
y=-3
y=-3
Hey there,
Ok so we need to put this into slope-intercept form so we can find the slope eaisly, (y=mx+b)
If we move x to the right side we are left with,
2y=-x-3
Next we divide by 2 to free up the y,
y=-1/2x-3/2, this is now in y=mx+b form. Making the slope -1/2
Hope this helped!
