So, this is pretty simple actually.
3^c2 * 8^c6 * 1 = 84
We have the following:

solving for x

The solution of x is equal to 28, therefore 12 is not a solution of the equation
What does gas cost answer then I will give you the answer
If the height is h, then h/65=sin70, so h=65sin70=61.08m approx.
<u>Answer-</u>
<em>The statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.</em>
<u>Solution-</u>
It solely depends on b, whether the function will have one or two or zero x intercept.
This plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e V shape, with vertex translated to (-a, b), instead of origin.
1- If b is zero, the graph will have exactly one x-intercept, at x= -a
2- If b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.
3- If b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.
∴ The statement is sometimes true.
