solving for the inverse of y = x² + 12x

Line 1:    x = y² + 12 x.      

Line 2    y² = x - 12 x.  

Line 3 is y²= - 11 x.

Line 4 is y = √(- 11x)  for x ≥ 0.

The error lies in Line 1. All x's have to be switched with y's and vice versa for the method to work.

As such Line 1 should be  x = y² + 12y  NOT (x = y² + 12 x)

Since Line one is wrong, it messes with all the other lines.

Answer:

x=-4

Step-by-step explanation:

2(x+6)=4

2x+12=4

2x=4-12

2x=-8

x=-4

Answer:

x = -4

Step-by-step explanation:

First distribute 2 among everything in the parentheses. So now you'll have 2x + 12 = 4

Next subtract 12 on both sides to get -8.

Lastly divide 2 on both sides to get x = -4

Hope this helps :)

Answer:

$12.33

Step-by-step explanation:

Since the bill is $68.50, and Jim wants to tip 18%, it will be $80.83 in total

18% = 0.18

since you don't want to DECREASE the bill, it's 1.18

1.18 x 68.5 = 80.83

hope this helped :)

Just subtract the original number from the new number, then you get the volume of the object that was put in the liquid!

new - original = volume of object

Answer:

-6√3 - 9√2

Step-by-step explanation:

So you distribute like normal:

-3√3 times 2 is -6√3

-3√3 times √6 is -3√18

You can simplify -3√18 into -9√2

(because 9 can be squared into 3 and you can multiply the 3 with the current 3 into 9)

(Also you have to divide 9 out of 18 since you are simplifying)

So the answer will be -6√3-9√2

Hope this helps!

Step-by-step explanation:

Using Pythagoras theorem,

Let the ratio of the sides be x

B²=H²-P²

B²= (25x)²-(21x)²

B²=625x²-441x²

B²=184x²

B=13.56x.

Answer:

A.make calculation easier

Relationship Equation between time and shrimps cleaned : S = 4T; Relationship is inversely proportional; Unit rate of change = 4

Given : 4 Shrimps cleaned every minute.

So, Shrimps cleaned 'S' = 4 times minutes taken 'T' ; S = 4T

The relationship between variables is proportional, as the dependent variable (shrimps) is constant multiples times the independent variable (time), & their ratio remains constant.

Unit rate of change denotes constant magnitude of change in a variable with other variable. It is 4 in this case, as time increases the shrimps.

Answer:

10. put a dot on the number 10

Step-by-step explanation:

3-(-5)-(-2)

when subtracting negatives, you actually end up adding

so

3+5+2=10

3 - (5) - (-2) = 10.

The solution will be positive 10 on the line.

Answer: perpendicular

Step-by-step explanation: You can do this (of course, you have to know the equations of the pairs of lines under consideration);

For each equation, put in form y = mx + b and compare their slopes (values of m).

If the m's are equal, the two lines are parallel;

if the product of the two m's equals -1, the two lines are perpendicular.

Answer:

$27.72

Step-by-step explanation:

The information that we have its

The cost gas its ​$3.60 per gallon

Irene​'s car had 5.3 gallons

Irene's car tank is 13 gallons

so now for the know, How much did Irene spend on gas?

First

The gas that its necessary for filled de tank its

13gallons-5.3gallons=7.7 gallons

The cost for 7.7 its

7.7g*$3.60/g= $27.72
