Answer:
- 9. B, 10. A, 11. A, 12. D
Step-by-step explanation:
<h3>Question 9</h3>
<u>The smaller number is x, the greater number is x + 4, their sum is 52:</u>
Correct choice is B
<h3>Question 10</h3>
<u>$8 and 9n should sum at least $80:</u>
- 8 + 9n ≥ 80 ⇒ 9n ≥ 72 ⇒ n ≥ 8
Correct choice is A
<h3>Question 11</h3>
<u>$43 and 3n should sum at least $70:</u>
- 43 + 3n ≥ 70 ⇒ 3n ≥ 27 ⇒ n ≥ 9
Correct choice is A
<h3>Question 12</h3>
<u>P books cost $10.01p and $9.96 for shipping, the total should be no more than $50:</u>
- 9.96 + 10.01p ≤ 50 ⇒ 10.01p ≤ 40.04 ⇒ p ≤ 4
Correct choice is D
Answer:1
Which of the following functions has a line of symmetry of x = 2?
Step-by-step explanation:
Here's the expression you can use to solve this:
let x = number of hooks Connor can make
5/6x <span>≤ 10
(6/5) 5/6x </span><span>≤ 10 (6/5) Now, multiply by the fraction's reciprocal to isolate x.
x </span><span>≤ 12 This means that Connor can make 12 hooks with 10 inches of wire.
</span>
10920 square inches, simply divide 720720/66 and you'll get your desired answer
