Which of the following is the correct graph of the solution to the inequality −8 greater than or equal to −5x + 2 > −38? (1 p
Svetlanka [38]

The inequality should read:

-8 \geq -5x + 2 > -38

Subtract 2 from all the terms:

-10 \geq -5x > -40

Divide all the terms by -5 to get x by itself (note that you flip the inequality signs as you divide by a negative):

\boxed{2 \leq x < 8}

The inequality is 2 ≤ x < 8.

A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.

The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.

I need to help my child do division but I don't know how to do it myself
Sedaia [141]
Well this is a hard question to answer, but this is how i would put it.

 You would take a number (lets use 15) and the second number (lets use 5) would determine how many times it would go into 15. In other words, 5 time x would equal 15 (5x=15). 5, being a factor of 15, would evenly fit into 15 three times.

Find the area to the nearest square foot of the shaded region below, consisting of a square with a circle cut out of it. Use
Simora [160]

Answer:

the area is 10 feet by 10 feet, 100 feet²

subtract the area of the circle from this.

you get it by A = r² * pi

so 5² * 3.14159...

=78.5398163397

100-78.5398163397

is roughly 21.46 square feet

ohaa [14]

Answer: The answer is (D) prevent the passge of certian molecules into the cell.

Step-by-step explanation: We have four option out of which one describes the functions of protein present in the phospholipid bilayer in the cell membrane.

Phospholipid bilayers are critical components of cell membranes. Its function is to act as a barrier to the passage of molecules and ions into and out of the cell. It allows selective substances and molecules to come in and go out of the membrane.

Thus, the correct option is (D).

How would you solve this problem 2/6×3= would you divide or multiply
Rainbow [258]
In the order of operation, multiplying or dividing don't take preference over the other. So with them, you work from left to right.

This means for this question, you first divide, then multiply.
