Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
= k, that is
k = -
y = - x ← equation of variation
When x = 20, then
y = - × 20 = - 10
Answer:
JL = 54
Step-by-step explanation:
JL = JK + KL
JK = KL
8x+11 =14x-1
12 = 6x
x = 2
substitute for x:
8(2)+11 + 14(2)-1 = JL
JL = 16+11+28-1
JL = 54
100 and -100 are the two solutions for the square root of 10,000
Answer: % increase ≈ 3433%
Step-by-step explanation:
Step 1: work out the difference (increase) between the tow numbers you are comparing.
Increase = New Number - Original Number
Step 2: Divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number x 100
Step 3: Plug in known values
Increase = 6.18
Original Number = 0.18
% increase = 6.18 ÷ 0.18 x 100
% increase = 34.333... x 100
% increase ≈ 3433%
