<h3><em><u>The equation to find the number of hours for which the total cost will be the same for the two services is:</u></em></h3><h3>12 + 5h = 18 + 3h</h3>

<em><u>Solution:</u></em>

Let "h" be the number of hours

Given that,

<em><u>Derrick's Dog Sitting charges $12 plus $5 per hour</u></em>

Cost : 12 + 5(number of hours )

Cost : 12 + 5h ---------- eqn 1

<em><u>Darlene's Dog Sitting charges $18 plus $3 per hour</u></em>

Cost: 18 + 3(number of hours)

Cost: 18 + 3h ---------- eqn 1

<em><u>For eqn 1 = eqn 2,  the number of hours for the total cost will be the same for the two services</u></em>

Therefore,

12 + 5h = 18 + 3h

Thus option A is correct

144 students enter a spelling bee, but only 1/6 of the group will make into the semi-final round, and only 2 /3​ that group will
DerKrebs [107]

Answer:

16 students

Step-by-step explanation:

144 students enter a spelling bee contest.

Step 1

For the semi final round we are told that only 1/6 of the group will make it into that round.

This is calculated as

1/6 × 144/students = 24 students.

This means that only 24 students would make it into the semi final rounds.

Step 2

We are also told in the question that only 2/3 of THAT group would make it into the final round.

" THAT" group been referred to in the question means the number students that made it to the semi final round

This is calculated as

2/3 of that group( the group that made it to the semi finals)

= 2/3 × 24 students

= 16 students.

Therefore, the number of students that will enter the final round of the spelling bee is 16 students.

Choice a:
<span>c + 7 ≤ 3
</span><span>c ≤ 3-7
</span><span>c ≤ -4
Choice a is a wrong choice

Choice b:
</span><span>c - 3 > 1
</span><span>c > 1+3
</span><span>c > 4
Choice b is a wrong choice

Choice c:
</span><span>c - 7 < 3
</span><span>c < 3+7
</span><span>c < 10

Plz help me find answer. what are the coordinates of slope when y= x/1–x² when dy/dx=1​
vova2212 [387]

Step-by-step explanation:

dy/dx

= d/dx [x / (1 - x²)]

= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²

= (1 + x²) / (1 - x²)².

When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.

=> 1 + x² = 1 - x²

=> 2x² = 0, x = 0.

Also when x = 0, y = (0) / [1 - (0)²] = 0.

Hence the coodinates is (0, 0).
