Answer:

Step-by-step explanation:
Let the missing number be x
Quadruple means 4 times
So According to the question,
4x - 20 = 4 is your answer
Hope this helps
31) ($6 * 2) + $6.25 + $4.25 + $20 = $42.50
32) $50 - $8.25 - $4.25 -$4.25 - $20 = $13.25
33) 6 * 15.99 = 95.94 | $100 - $95.94 = $4.06
34) $10.50 * 8 = 84 | $100 - $84 = $16
Hope this helps! ^^
Point slope is nicer
y-y1=m(x-x1)
goes through the point (x1,y1) and has a slope of m
slope itnercept
y=mx+b
m=slope
b=y intercept
first find slope
slope between 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(7,82) and (4,18)
slope=(18-82)/(4-7)=-64/-3=64/3
point slope
point is (7,82) or you can do (4,18)
I'll do both
y-82=(64/3)(x-7) or
y-18=(64/3)(x-4)
those both work
slope intercept
slope is 64/3
y=64/3x+b
find b
input a point
(4,18)
18=64/3(4)+b
18=256/3+b
minus 256/3 from both sides
note: 18=54/3
-202/3=b
y=64/3x-202/3 is equation in slpe intercept
Answer:
c
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
P.s. Coefficient always goes before the variable
= 2b + 4
= 2(3) + 4 Substitute b for 3
= 6 + 4
= 10
