Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = 
← k is the constant of variation
y = - 
x ← represents direct variation with k = -
Answer:
x has a greater change
Step-by-step explanation:
Answer:
look up the distributive property and solve the problem.
Step-by-step explanation:
(1)
10(1+3x)=-20
Cross multiply.
10+30x=-20
Isolate x on one side. So you would subtract 10 on each side. and one side will cross each other out. leaving you with,
30x=-20-10
Subtract 10 from -20.
30x=-30
Divide each side by 30 to get x.
30x÷30=-30÷30
Therefore,
x=-1
(2)
-5x-8(1+7x)=-8
Cross multiply -8(1+7x)
-5x-8-56x=-8
Isolate all x's on one side. So you would add 8 on each side. and one side will cross each other out. leaving you with,
-5x-56x=-8+8
Add 8 to -8.
-5x-56x=0
Subtract -56x from -5x
-61x=0
Divide each side by -61
-61x÷-61=0÷-61
Therefore,
x=0
Answer:
y=-3x+4
Step-by-step explanation:
im assuming that you need the equation of the table
to find slope, y2-y1/x2-x1 10-4/-2-0
6/-2=-3 slope=-3
y=mx+b just sub in the numbers from a point in the table
10=-3(-2)+b
10=6+b
b=4
y=-3x+b
