Answer:
C = 50p +900
Step-by-step explanation:
Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).
Equation: C = 900 +50p
__
The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.

Edgenuity’s sample response for this question:
Sublimation occurs because the atoms in a solid must gain enough energy to form a gass without passing through the liquid state. Low air pressure and large amounts of energy, often in the form of heat, allow the atoms to move fast enough to overcome the attractive forces between them.
If you need an original response here’s my take!!:
Sublimation happens when a solid turns directly into a gas. For this to happen, there must be low air pressure and immense heat energy. This allows atoms to quickly move and perform sublimation.

Answer:
#6 is 17 days
Step-by-step explanation:
This is how I answered it
1) 2750 = 550 + 125x
2) subtract 550 from each side
2750-550=2200
so the left over equation is:
2200 = 125x
3) divide each side by 125 to get x by itself
2200÷125= 17.6
4) you are left with: x = 17 days
Briefly explain how to convert a fraction to its decimal
form.
Answer:
you just divide
Step-by-step explanation:
Just divide the top of the fraction by the bottom, and read off the answer!
Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem
Step-by-step explanation:
Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

What is the greatest common factor 12x^5 and 8x^3
Hey there! I'm happy to help!
Let's see what makes 12x^5.
3·2·2·x·x·x·x·x
And for 8x^3...
2·2·2·x·x·x
We see that both of these have two 2s and 3 xs, so our GCF is 2·2·x·x·x which is 4x^3.

We know that 6x(-7) is -42 and we also know that 6+(-7) is -1.
So we can write

[tex](x-7)(x+6)[/tex]
So our solutions are [tex]x=7,-6[/tex]

A point lies on AB¯¯¯¯¯ and is located 3/7 the distance from A to B. What are the coordinates of the point? (4, 3) (7, 3) (9, 3) (12, 3)
Answer:
(4,3)
Step-by-step explanation:
This doesn't even take any math really, just deductive reasoning :)
We know the line segment stretches from one to 15, meaning there are 14 points on the line as there is (1,2,3, etc.)
14/2 obviously equals 7, so just plug it in from there.
12 is too far up on the line to be less than half, so (12, 3) is wrong
^ this goes for (9, 3) as well
7 is literally the halfway marker, so there is no way it could be (7, 3)
Making the answer (4, 3) because not only is it the last one remaining but it makes the most sense, being less than one half of the segment

Cheryl wants you find the number of hours 7th graders do work at home each week. There are 297 boys and girls in 7th grade, Cheryl random surveyed 50 girls in the entire school to find a number of our 7th graders do homework each week described why she would get a biased sample
Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)
Answer:
Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.
The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.
The results would not be a representative sample of the population.
