Answer:
b= -18
Step-by-step explanation:
x=3, y= -6, m=4
y=mx+b
-6 = 4 x 3 + b Solve for b
-6 = 12 + b
-6-12 = b
b= -18
Question 1:
c2=a2+b2
c2=5(squared)+7(squared)
c2= 25+49
c=74
c=
question 2:
c2=a2+b2
c2=24(squared)+18(squared)
c2=576+324
c=900
c=
9514 1404 393
Answer:
- arithmetic: 130
- geometric: ±50
Step-by-step explanation:
<u>Arithmetic sequence</u>
The terms of an arithmetic sequence have common difference. If the missing term is x, then the difference between terms is the same:
x -250 = 10 -x
2x = 260 . . . . . . add 250+x to both sides
x = 130 . . . . . . . . divide by 2
The missing term of an arithmetic sequence is 130.
(the common difference is -120)
__
<u>Geometric sequence</u>
The terms of a geometric sequence have a common ratio. If the missing term is x, then the ratios between terms are the same:
x/250 = 10/x
x^2 = 2500 . . . . . . . multiply both sides by 250x
x = ±√2500 = ±50 . . . take the square root
The missing term of a geometric sequence is +50 or -50.
(the common ratio is ±1/5)
