Answer:
A. x<18
B. Given
Step-by-step explanation:
Citizens under the age of 18 are not allowed to vote. This means that 18 is included within the ones that can vote.
let x = the citizens under the age of 18
x < 18 is your inequality (Part A)
For the solution, because it does not include 18, you'll use an open dot (a non-filled in circle) placed on 18, and going to the left (less than).
Answer:Roxana hourly paid is $12
Step-by-step explanation:
overtime pay=p
normal hourly rate=r
p=1.5r
72/4=18
p=$18/hr
p=1.5r
18/1.5 =1.5r /1.5
12=r

<span>(x-4)^2 -28 = 8
</span>(x-4)^2 = 8 + 28 = 36
<span>(x-4) = +/-6
x = 6 + 4 or -6 + 4
x = 10 or -2
2.
Mistake in </span><span>Step 5: x – 3 = 16
</span><span>Step 4: (x – 3)² = 16
</span><span>Step 5: (x – 3) = +/-4
Step 6: x = 4 + 3 or -4 + 3

</span><span>quadratic eqn x = [-b +/- sqrt(b^2-4ac)]/2a
where in this case
a = 1, b = -4, c = 3
x = </span> [-(-4) +/- sqrt((-4)^2-4*1*3)]/2*1
= [4 +/- sqrt(16 - 12)]/2
<span>= [4 +/- sqrt(4)]/2
= [4 +/- 2]/2
= 6/2 or 2/2
= 3 or 1
