Answer:
f(x) = sqrt(x + 6)
y = sqrt(x + 6)
x = sqrt(y + 6)
Stx^2 = y + 6
x^2 - 6 = y
red line: f(x) = sqrt(x + 6)
green line: f^-1(x) = x^2 - 6
70) perpendicular means you take the number in from of the x and flip it and switch the sign. that number will become your slope (m).
y=mx+b. plug in slope and point
-5=(7/9)(-4)+b. multiply
-5=(-28/9)+b. add over -28/9
b= -17/9. plug b and slope into original equation
y=(7/9)x+(-17/9) get rid of frac by multi by 9
(y=(7/9)x+(-17/9))*9
9y=7x+-17. subtract over 7x
-7x+9y=-17. answer
Same goes for the rest. number 72 the perp slope will be (1/3) and for 74 the answer will be x=-5 (that is a weird case)

the correct answer is 25.07 X 5.4= 135.378
Answer:
The ordered pair is a solution of the linear equality.
Step-by-step explanation:
Whenever you have an equation like that—it's always helpful to remember x come before y in an ordered pair. (x, y). So, from there plug the numbers into the inequality and solve.
