Answer:
slope is the rate at which a function progresses. y intercept a point that passes through they x axis when it is 0. ex) (0,9)
equation written as y=ax +b
b = y intercept
ax = slope
ax = y2-y1/x2-x1
take 2 random points
(0,3) (-2,0)
slope : 0-3/-2=0 = -3/-2 = 3/2
y intercept = 3 because x = 0 and y =3
<u>equation = y =3/2x + 3</u>
Step-by-step explanation:
6. domain=age
range= number of pets
it is not a function because an x value repeats
7. domain=1,2,3,4,5
range= 50, 100, 150, 150, 200
it is a function because the lines don't connect
1 board that is 10 feet long and make that into 6 table legs. Take the amount we have over the amount we want, so 10 over 6 which is 1.6666667 feet which is the longest each leg can be for a 10-foot board.
Answer:
8cm and 9cm
Step-by-step explanation:
8cm and 9cm would be the two possible lengths for the triangle because for the triangle to work you need the other two other sides when added together needs to be greater then 13. Furthermore 5 + 8 = 13 and as 13 is the same length as the one side that is given, a triangle couldn't possibly be formed as it would just be a straight line. Moreover, this is the same with 6 + 7 which is also 13. 7 + 2 is 9 and because 9<13 a triangle couldn't possibly be formed. Finally, 8 + 9 which equals to 17 are the only two possible lengths for the triangle as 17 > 12.
