9 + 15 / 5 x 13 =
9 + 3 x 13 =
9 + 39 = 48
Y=|x-7| because in order to go to the right you have to subtract the amount from x
3n=27+3
you can do anything as long as you do it to both sides
3n=27+3
add like terms
27+3=30
3n=30
divide both sides by 3
n=10
You add all the sides together for perimeter
Answer: See attached
Step-by-step explanation:
[1] Looking at the function, this will be a parabola.
[2] We know that the x-intercepts, where the line hits the x-axis, will be -1 and 2 because of the factored part given
-> (x + 1)(x - 2)
-> (x + 1) gives us -1 and (x - 2) gives us 2
[3] We will graph the given function.
-> See attached
-> <em>I kept the scale the same as the screenshot you gave (which is 5 to -5 for both the y-axis and the x-axis)</em>
