Answers

The right answer for the question that is being asked and shown above is that: "a. reflection." After the square undergoes an isometric transformation, its new vertices are Q'(0,0), U'(4,0), A'(4,-4), and D'(0,-4). The option that best describes the type of transformation that maps QUAD onto Q'U'A'D' is that a. reflection

Giselle works as a carpenter and as a blacksmith. She earns $20\$20 $20 dollar sign, 20 per hour as a carpenter and $25\$25 $25 dollar sign, 25 per hour as a blacksmith. Last week, Giselle worked both jobs for a total of 3030 30 30 hours, and earned a total of $690\$690 $690 dollar sign, 690 . How long did Giselle work as a carpenter last week, and how long did she work as a blacksmith? Giselle worked as a carpenter for hours and as a blacksmith for hours last week.

Answers

c = # of carpenter hrs , b = # of blacksmith hrs

c + b = 30...c = 30 - b
20c + 25b = 690

20(30 - b) + 25b = 690
600 - 20b + 25b = 690
-20b + 25b = 690 - 600
5b = 90
b = 90/5
b = 18 <== hrs worked as blacksmith

c + b = 30
c + 18 = 30
c = 30 - 18
c = 12 <== hrs worked as carpenter

Answer:

Carpenter: 12 hours and Blacksmith: 18 hour

The surface of Grand Lake is at an elevation of 648 ft. During the current drought, the water level is dropping at a rate of 3 inches per day. If this trend continues write an equation that gives the elevation in feet of the surface of Grand Lake after x days.

Answers

Final answer:

The equation representing the elevation of Grand Lake after x number of days, given a decrease of 3 inches per day, is Elevation = 648 - 0.25x, where 0.25 is the daily loss rate in feet and x represents the number of days.

Explanation:

The subject of this question is the application of linear equations to real-world problems, specifically in the context of environmental changes. Given the initial elevation of Grand Lake and the daily rate of water level decrease, we can write an equation that represents the elevation of the lake's surface after x days.

The initial height of the lake is 648 feet. Every day, the lake elevation drops by 3 inches. However, our rate is given in inches and the initial elevation is in feet. We should convert the rate from inches to feet. Since there are 12 inches in a foot, 3 inches is equal to 3/12 = 0.25 feet.

So after one day, the lake would be at 648 - 0.25 = 647.75 feet. After two days, the lake would then be at 648 - 2(0.25) = 647.50 feet, and so on. In general, after x days, the elevation of the lake would be 648 - x(0.25)

Therefore, the equation we are looking for is: Elevation = 648 - 0.25x

Which properties should you use to solve the equation4x+2= 18 ?

Answers

x=4

4x+2=18

x has to be alone, so you dived both sides by 2

4x=18-2

4x=16

divide both sides by 4

x=4

Answer:

Addition property of equality and multiplication property of equality

Step-by-step explanation:

Addition Property of Equality: This property states that you can add or subtract the same value to both sides of an equation without changing its solution.

Here's the step-by-step solution, emphasizing the properties used:

Start with the equation:

4x + 2 = 18

Use the Addition Property of Equality to isolate the variable "x." Subtract 2 from both sides to move the constant term to the other side of the equation:

4x + 2 - 2 = 18 - 2

Simplify both sides by applying the Addition Property of Equality:

4x = 16

To further isolate "x," use the Multiplication Property of Equality, which states that you can multiply or divide both sides of an equation by the same nonzero value. Divide both sides by 4 to solve for "x":

(4x) / 4 = 16 / 4

Simplify both sides using the Multiplication Property of Equality:

x = 4

So, in solving the equation 4x + 2 = 18, you primarily used the Addition Property of Equality and the Multiplication Property of Equality to isolate and solve for "x."

y=x^2+6x
Apply the value of y into the equation below:
4x-y=-24
4x-(x^2+6x) = -24
4x-x^2-6x = -24
x^2+2x-24=0
(x+6)(x-4)=0
Therefore x can be -6 or 4
If x = -6
Then y = (-6)^2+6(-6) = 36 -36=0
If x = 4
Then y = (4)^2 + 6(4) = 16 + 24 = 40

A certain forest covers an area of 2,000 square kilometers. Suppose that each year this area decreases by 6%. What is the function that bestrepresents the area of the forest each year and how much area remains after 12 years? Round your answer to the nearest square kilometer.Hint: Use the formula, f(x) = P(1 + r)x.

Answers

The question gives you the formula to use, but it's printed wrong.
The 'x' is an exponent after the (1 + r).

All you have to do is take the formula, and write the numbers into it
that are also given.

The key thing to spot is that the forest is decreasing, so the 'r' is negative,
just as if you had money in a savings account and every year the bank took
6% out of it.

So the formula to use is    f(x) = P (1 + r) ^x

P = 2000
r = -0.06
      f(x) = 2000 (1 - 0.06)^x
         = 2000 (0.94)^x

The amount left after 12 years is

   2000 (0.94)¹² =

   2000 (0.476) = 951.8 square kilometers.
