Answer:
[0, ∞)
Step-by-step explanation:
The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).
If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).

Tell whether (-1,3) is a solution of the inequality whose graph is shown.
Answers
Answer: No.
Reason: (-1, -3) is (x, y) so, let's find -1 on the X scale first. Alright, -1 is in the blue, which is a great start. Now, it's -3 on the Y portion. And when you graph that, it's not in the blue shaded area, so no, it's not a solution. (TIP: Solution is the Shaded Area)

At a real estate agency, an agent sold a house for $396,000. The commission rate is 7.5% for the real estate agency and the commission rate for the agent is 20% of the amount the real estate agency gets. How much did the agency make on the house? How much did the agent earn in commission?
Answers
Answer:
$29,700 and $79,200
Step-by-step explanation:
Step one:
given
The selling price of the house is $396,000
The commission rate is 7.5% for the real estate agency
The commission rate for the agent is 20%
Step two:
1. How much did the agency make on the house?
This amount is 7.5% of $396,000
= 7.5/100*396,000
= 0.075*396,000
=$29,700
2. How much did the agent earn in commission?
This amount is 20% of $396,000
= 20/100*396,000
= 0.2*396,000
=$79,200

What is the result when 12x3 + 20x2 + 11x + 2 is divided by 3x + 2?
Answers
Answer: 3x + 2) 12x� + 20x� + 11x + 2
Divide the first term 12x� by 3x: %2812x%5E3%29%2F%283x%29=4x%5E2
and write 4x� above the 20x�:
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
Multiply the 4x� by the (3x + 2) getting 4x%5E2%283x%2B2%29=12x%5E3%2B8x%5E2 and
write it under the first two terms and draw a line underneath:
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
Subtract %2812x%5E3%2B20x%5E2%29-%2812x%5E3%2B8x%5E2%29=12x%5E3%2B20x%5E2-12x%5E3-8x%5E2=12x%5E2,
and write 12x� under the line under 8x�, like this:
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x�
Now bring down the next term + llx and write in next to the 12x�
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
Divide the first term on the bottom 12x� by 3x: %2812x%5E2%29%2F%283x%29=4x
and write + 4x above the 11x at the top, like this:
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
Multiply the 4x by the (3x + 2) getting 4x%283x%2B2%29=12x%5E2%2B8x and
write it under the first two terms and draw a line underneath:
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
Subtract %2812x%5E2%2B11x%29-%2812x%5E2%2B8x%29=12x%5E2%2B11x-12x%5E2-8x=3x,
and write 3x under the line under 8x, like this:
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x

Now bring down the last term + 2 and write in next to the 3x
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
Divide the first term on the bottom 3x by the 3x at the left:
%283x%29%2F%283x%29=1 and write + 1 above the + 2 at the top,
like this:
4x� + 4x + 1
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
Multiply the + 1 by the (3x + 2) getting 1%283x%2B2%29=3x%2B2 and
write it under the two terms at the bottom and draw a line
underneath:
4x� + 4x + 1
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
3x + 2
Subtract %283x%2B2%29-%283x%2B2%29=3x-3x=0,
and write 0 under the line under 2, like this:
4x� + 4x + 1
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
3x + 2
0
Now you are done and the answer is 4x%5E2%2B4x%2B1 and
since the remainder is 0 you do not have to put it over
the divisor 3x+%2B+2 and add it on like you do when
the remainder is not 0.

What value of m makes the equation true? 2(m+1.5)=m+10
Answers
Answer:
2(m+1.5)=m+10 m=7
Step-by-step explanation:
Distribute 2 to the m and the "1.5". You get 2m+3
You then drop the m+10 and the equation is 2m+3 = m+10
After that, you subtract the "m" over to the "2m" which becomes m+3 = 10
You then subtract the 3 over to the 10 which finally comes to m=7

Answer:
D
Step-by-step explanation:
The reason D is false is because it states that Sasha can make 2 bags per minute while she cant make 2 bags per minute. She can make half a bag per minute. D is wrong 100%
Answer:
Step-by-step explanation:
Distance covered = speed × time.
Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.
This means distance covered while running would be
3.8 × 1/2 = 1.9 meters
Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be
1.5 × 1/2 = 0.75 meters
Total distance that Sasha covered while running and walking in 60 minutes would be
1.9 + 0.75 = 2.65 meters
