Answer:
C. ≥
Step-by-step explanation:
Values of y on or above the line are "greater than or equal to" those on the line. The inequality will have the form ...
y ≥ (expression for the line)
1 Simplify 7x+16+47x+16+4 to 7x+207x+20<span> 7x+20=x<span>7x+20=x</span></span>
2 Subtract 7x from both sides<span> 20=x-7x<span>20=x−7x</span></span>
3 Simplify <span>x-7x<span>x−7x</span></span> to <span>-6x<span>−6x</span></span>
<span>20=-6x<span>20=−6x</span></span>
4 Divide both sides by −6 -20/6=x
5 Simplify 20/6 to 10/3 -10/3=x
6 Switch sides
x=-10/3<span><span><span> </span></span></span>
Step-by-step explanation:
P = height of Paul.
S = height of Steve.
t = height of Theresa.
P = 1 1/2 t - 16 = 3t/2 - 16
S = 1 1/3 t - 6 = 4t/3 - 6
because Paul and Steve have the same height, we can say
P = S
3t/2 - 16 = 4t/3 - 6
3t/2 - 10 = 4t/3
9t/2 - 30 = 4t
9t - 60 = 8t
t = 60
so,
Theresa is 60" tall.
Paul and Steve are 4×60/3 - 6 = 240/3 - 6 = 80 - 6 = 74" tall
Step-by-step explanation:
inverse = √((x-10)/4)
