Answer:
-14c+10
Step-by-step explanation:
add the -8c and -6c together and add 7 and 3 together. number comes after the variable
300/ 15 = 20
divide bar graph into 20 equal sections
each section represents one week
algebra
number of weeks = x
15x = 300
x = 300/15
x = 20
Know the answer again it 10 2/3 its easy like the last one.
Y= 5x-45
On your graph go by 5's
On the y go down 9 which going by 5 makes it -45
Then go up 5 and one to the right and plot points keep going. 25/5=5
