Answer:

2/x

Step-by-step explanation:

The easy way:

take point (2,1) on graph g

subst the values into g(x)=a/x

1=a/2

a=2

thus -> 2/x

The value of a is 2 for the transformed function g(x) = a/x.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The value of a is calculated as,

Take point (2,1) on graph g and substitute the values into g(x)=a/x

1=a/2

a=2

Therefore, the value of a is 2 for the transformed function g(x) = a/x.

Answer:

x = 8

Step-by-step explanation:

Base angles of isoceles triangle are equal

5x + 10 = 50

5x = 40

x = 8

Answer:

Step-by-step explanation:

3ln(4) = 2ln(x)

ln(4³) = ln(x²)

4³ = x²

(2²)³ = x²

2⁶ = x²

x = ±√2⁶ = ±2³ = ±8

However, the argument of a logarithm must be positive, so x=8.

The solution set of the equation is {8, -8}, but we can discard the negative solution as it is not physically meaningful in this context. So, the final solution set is {8}. Option D is correct.

To solve the equation, we can use the logarithmic identity that states:

n * log(a) = log(aⁿ)

Using this identity, we can rewrite the equation as:

In(4³) = In(x²)

Simplifying both sides using the natural logarithm properties, we get:

In(64) = In(x²)

Taking the exponential of both sides, we have:

[tex]e^{In 64} = e^{In x^2}\\64 = x^2[/tex]

Taking the square root of both sides, we get:

x = ±8

However, we must check if either of these solutions makes the argument of the natural logarithm negative, which is not allowed. Since the argument of the natural logarithm is positive for both x = 8 and x = -8, both solutions are valid.

Therefore, the solution set of the equation is {8, -8}, but we can discard the negative solution as it is not physically meaningful in this context. So, the final solution set is {8}.

Simplifying

2x2 + 6x + 4 = 24

Reorder the terms:

4 + 6x + 2x2 = 24

Solving

4 + 6x + 2x2 = 24

Solving for variable 'x'.

Reorder the terms:

4 + -24 + 6x + 2x2 = 24 + -24

Combine like terms: 4 + -24 = -20

-20 + 6x + 2x2 = 24 + -24

Combine like terms: 24 + -24 = 0

-20 + 6x + 2x2 = 0

Combine like terms: -5 + 5 = 0

0 + -1x = 0 + 5

-1x = 0 + 5

Combine like terms: 0 + 5 = 5

-1x = 5

Divide each side by '-1'.

x = -5

Simplifying

x = -5

Answer:

Set the factor '(-5 + -1x)' equal to zero and attempt to solve:

Jamila need's 375g of butter

Step-by-step explanation:

12 biscuits , but she wants to make 36,

12x3 = 36 so times to rest of the ingredients by 3

250x3=750g Oats

125x3=375g Butter

100x3=300g Sugar

2x3= 6 tablespoons of syrup

Jamila needs 375 g of butter to make 36 biscuits.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If the recipe makes 12 biscuits and Jamila wants to make 36 biscuits, she needs to triple the recipe.

To triple the amount of butter, we can multiply 125 g by 3:

125 g x 3 = 375 g

Therefore,

Jamila needs 375 g of butter to make 36 biscuits.

Answer:

YeS, it is a solution

Step-by-step explanation:

Here, we want to check if -6 is a solution to the question

What we have to do is to replace x by -6

If what we have on the left equals that on the right, then -6 is a solution

Thus, we have it that;

3(2(-6) -8)

= 3(-12-8)

= 3(-20) = -60

for the right hand side

-4 (15) = -60

This means both sides are equal and that -6 is a solution

Answer:

The length and width of the patio are 18¹/₃ feet and 6²/₃ feet respectively.

Step-by-step explanation:

Let L and W be the length and width of the patio respectively. Since the patio is a rectangle, its perimeter, P = 2(L + W). This perimeter equals the length of string of lights which is 45 ft.

Now, the length of his patio, the side along the house, is five feet longer than twice its width implies that L = 2W + 5.

Substituting L into P, we have

P = 2(L + W)

= 2(2W + 5 + W)

= 2(3W + 5)

= 6W + 5

Since P = 45 feet,

6W + 5 = 45

6W = 45 - 5

6W = 40

W = 40/6

W = 20/3 feet

W = 6²/₃ feet

Since L = 2W + 5, substituting W = 20/3 into L, we have

L = 2W + 5

= 2(20/3) + 5

= 40/3 + 5

taking the L.C.M, we have

= (40 + 15)/3

= 55/3 feet

= 18¹/₃ feet

So, the length and width of the patio are 18¹/₃ feet and 6²/₃ feet respectively.

Answer:

7.5 laps

Step-by-step explanation:

First, you wanna figure out how many yards is in one lap

to do this, you would multiply 100 and 4 (four because there's four equal sides  in one lap)

100 x 4 = 400

You know their speed is 5 yards per second, so you wanna find out how many seconds they will be running

to do this, you multiply 60 (sixty because there's sixty seconds in one minute) and 10 (ten because that's the given amount of minutes)

60 x 10 = 600 seconds

now to found out how much they will run in 10 minutes you will multiply 600 by 5

600 x 5 = 3000 yards

now to find how many laps this is, you can divide 3000 yards by 400 yards

3000 ÷ 400 = 7.5 laps
