A student found the solution below for the given inequality. Which of the following explains whether the student is correct? The

student is completely correct because the student correctly wrote and solved the compound inequality. The student is partially correct because only one part of the compound inequality is written correctly. The student is partially correct because the student should have written the statements using “or” instead of “and.” The student is completely incorrect because there is “ no solution “ to this inequality.

The statement which best explains whether the student is correct is: D. the student is completely incorrect because there is "no solution" to this inequality.

<h3>What is an inequality?</h3>

An inequality refers to a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

Since |x-9| is greater than or equal (≥) to zero (0), we can logically infer that this student is completely incorrect because there is "no solution" to this inequality.

Which absolute value function has a graph that is wider than the parent function, f(x) = |x|, and is translated to the right 2 u
Mariulka [41]
Case 1:  If we multiply f(x) = |x| by a fraction greater than zero and less than 1, the width of the resulting graph will increase.  If the vertex of the original function is moved 2 units to the right, then we'd replace |x| with |x-2|  Only the coefficient (3/4) satisfies the "wider graph" requirement here.

Next time you list answr possibilities, please type them in only one per line, or separate them with commons, semicolons or the like.

Today Zack sold twice as many bags of popcorn at the ball game as he sold last Saturday. In the 2 days he sold a total of 96 bag
Alexeev081 [22]

Answer:

s=32\\t=64

Zack sold 32 bags of popcorn last Saturday, and 64 bags of popcorn today.

Step-by-step explanation:

Start by determining what information the question gives us, and what we need to find.

Given:

Zack sold <em>twice</em> as many bags of popcorn as he sold last Saturday

He sold <em>96 bags</em> altogether in the 2 days

Find:

s, number of bags he sold last Saturday

t, number of bags he sold today

Equation/System of Equations:

t=2s (OR "number of bags he sold today = number of bags he sold last Saturday multiplied by 2, or twice the amount he sold last Saturday)

t+s=96 (OR "number of bags he sold today + number of bags he sold last Saturday is equivalent to the amount of bag he sold altogether which is 96 bags as given by the question)

Solve:

We can solve this system of equations using substitution. In this case, we can substitute "2s" for "t" into the second equation giving us...

2s+s=96\\3s=96

Divide both sides by 3. Notice that the Division Property of Equality states that if you divide on side of the equation by something, you must divide the other side by the same quantity.

s=\frac{96}{3}\\s=32

Substitute 32 in for "s" to solve for "t"...

t=2s\\t=2(32)\\t=64

Answer:

Zack sold 32 bags of popcorn last Saturday, and 64 bags of popcorn today.

A scientist begins an experiment with a petri dish containing a culture of bacteria cells and records the cell growth every hour
olya-2409 [2.1K]
<span>A scientist begins an experiment with a petri dish containing a culture of bacteria cells and records the cell growth every hour. At 1 hour, the bacteria had grown to 880 cells, and at 2 hours, had grown to 3,520 cells. Which function can be used to represent the relationship between the number of bacteria cells, y, and the time in hours, x? 
y = 4 x
y = 220(4) x
y = 880(4) x
y = 880(0.25) x </span>
