8. the graph shows the relationship between temperature in degrees celsius and
temperature in degrees fahrenheit,
degrees celsius
20
40
60
80 100 120 140 160 180 200 220 240
degrees fahrenheit
a. mark the point on the graph that shows the temperature in celsius when it is 60
degrees fahrenheit
b. mark the point on the graph that shows the temperature in fahrenheit when it
is 60 degrees celsius.
c. water boils at 100 degrees celsius. use the graph to approximate the boiling
temperature in fahrenheit, or to confirm it, if you knew what it is.
d. the equation that converts celsius to fahrenheit is c = (f - 32). use it to
calculate the temperature in celsius when it is 60 degrees fahrenheit. (this
answer will be more exact than the point you found in the first part.)

d) 140/9 or alternately 15 5/9 or 15.5

Step-by-step explanation:

Follow the line on the graph with the given number either in Fahrenheit or in Celsius until it meets up with the line of conversion. Where it meets on the line, mark the graph

hope this helps

i would need to see the dot plot : )

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
