The total that Robert had to pay for the car will be $1,575.
The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Robert bought a used car for $1,500. If the sales tax is 5%.
Let 'x' be the total price that he paid. Then the equation is calculated as,
5% = [(x - 1500) / 1500] x 100
Simplify the equation, then we have
0.05 = (x - 1500) / 1500
75 = x - 1500
x = 1500 + 75
x = $1575
The total that Robert had to pay for the car will be $1,575.

thank you!!!!!
The equation, 9x-6y=-72 in slope-intercept form is .
An equation is a mathematical statement that shows that two mathematical expressions are equal.
The standard form of equation in two variable is y= mx+b,
where y is the dependent variable
x is the independent variable
a is the intercept term
b is the slope
Given the following equation:
9x-6y=-72.......................1
Convert it into standard format y=mx+b,
Divide the equation by 6,
On multiplying the equation by -1.
On solving, to represent it into standard form:
On comparing it with standard equation,
Slope, m=3/2 and Intercept, b=12
Thus, slope-intercept form is .

an even function has symmetry about the x axis
this means that if you fold the graph over the y axis, the function will map over itself
in number terms, if f(x) is an even function, then f(x)=f(-x)
an example is f(x)=x²
an odd function has symmetry about the origin
it is kinda confusing, but if g(x) is an odd function, g(-x)=-g(x)
an example is g(x)=x³
the first one (f(x)) seems to be neither
h(x) one, notice for x=2 and -2, the values are negative of each other, this tells us that it's an odd function
g(x), replacing x with -x gives us -|-2x|+3=-|2x|+3, same function, even function
