NEED HELP ASAP, PLEASE HELP!! Graph the equations to find the solution(s) to the system.

y=x−1y=13(x+2)(x−4)

Use the Line tool to graph the line.

Use the Parabola tool to graph the parabola. Choose maximum or minimum point first and then a point on the parabola.

step-by-step explanation:

because of the levels

were is the equation

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

the answer is d

hope this
