Answer:

(-1,-2)

Step-by-step explanation:

Generally, the absolute value function can be expressed like so:

f(x) = y = a|x-h|+k, where vertex: (h,k)

Rewriting our function here ever so slightly gives us: y = 3|x-(-1)|+(-2)

So the vertex is at (-1,-2)

Suppose that y varies directly with x and y=10 when x=20. What is y when x=15

Likurg_2 [28]

Answer:

y=kx

subst y=10 and x=20 into the above

10=k20

k=10/20

k=1/2

therefore relationship: y=1/2x

subst x=15 into the relationship

y=1/2(15)

y=7,5

Step by step explanation:

Step 1: when they say y varies directly with x they mean y is proportional to x
step 2: so y=kx where k is the constant
step 3: is to substitute y=10 and x=20 into the above equation y=kx
step 4: you will end up with 10=k20 then divide both sides by 20 so that k becomes the subject of the formula 
step 5: your answer from the above will be k=10/20 so the relationship is y is directly proportional to 1/2 x what you did here is that you substituted k for 1/2 in the equation in step 3
step 6: is to finally substitute x=15 into the equation y=1/2x to finally get your answer y=7,5.

The snowboard Hannah wanted originally cost $109.It had been marked down 10% and then another 12%. A tax of 6% was added to the

lara [203]

Take 10% of the snowboard price.

10% = 0.1

109 * 0.1 = $10.90 (10% discount)

109 - 10.9 = $98.10 (Price with discount).

Take 12% of the new snowboard price.

12% = 0.12

98.1 * 0.12 = 11.772 (Round to 11.77)

98.10 - 11.77 = $86.33 (Final discounted price)

Take 6% tax on the new snowboard price.

6% = 0.06

86.33 * 0.06 = 5.1798 (Round to 5.18)

86.33 + 5.18 = $91.51
