4. E is between D and F. If DE = 3x + 2, EF = 18, and DF = 5x, find the value of x.

The angle x in the parallel line is 123 degrees.

In the diagram, l₁ and l₂ are parallel.

l₃ and l₄ are perpendicular to each other.

Since l₁ and l₂ are parallel lines, the line l₃ is a transversal that cut across the parallel lines.

Angle relationship are formed such as corresponding angles, alternate angles, vertically opposite angle etc.

Therefore,

57 + x  = 180°

x = 180 - 57

Therefore,

x = 123 degrees.

Answer:Explanation:

Option 1: Vertically compressed by a factor of 4, reflected across the x-axis, and shifted right 6 units and down 2 units.

iven the parent function:

If y is vertically compressed by a factor of 4, we have:

Next, a reflection across the x-axis will give:

If the result is shifted

Finally, a shift downwards by units gives:

Thus, the graph of g(x) is the graph of y vertically compressed by a factor of 4, reflected across the x-axis, and shifted right 6 units and down 2 units.

he firsyt option is correct.

Angle JKL has a measure of 24 degrees while angle LKM has a measure of 12 degrees

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following angles

From the attached figure, we can see that:

Angle 1 is twice the measure of angle 2

This is so because, the angle 1 is the vertex angle of an isosceles triangle

While the angle 2 is half of it

So, we have

Angle 1 = 2 * Angle 2

Substitute the known values in the above equation

So, we have

2 * 3x = 5x + 4

Evaluate the product

So, we have

6x = 5x + 4

Evaluate the like terms

x = 4

Substitute x = 4 in the equations JKL=5x+4 and LKM=3x

So, we have

JKL= 5 x 4 + 4

LKM = 3 x 4

Evaluate the equations

So, we have

JKL= 24

LKM = 12

Hence, the measures of the angles are JKL= 24 and LKM = 12, respectively

Answer: [tex]y=-((x-2)/\sqrt{2} )^{2} +4[/tex]

Step-by-step explanation:

This equation has it's parabola starting at (2,4)

So, we know that our equation will include (x-2) and +4

Next, we see the parabola is upside down, so we need a -

Next, we see the equation is wider than normal, so we need to divide x by something.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be A

The number A = 9³

The value of A = 729

Now , the number 9³ can be expressed as the power of 3

So , the equation will be

9³ = ( 3² )³

    = 3³ˣ²

    = 3⁶

    = 729

Therefore , the value of 9³ = 3⁶

Hence , The value of 9³ = 3ˣ and x = 6

9³ = 3 x 3 x 3 x 3 x 3 x 3

9³ = 3⁶

Step-by-step explanation:

The multiplicative inverse property states that any number multiplied by its multiplicative inverse (also called reciprocal) results in 1.

It is known that:

Therefore, 40 quarts in gallons is:

So to fill 40 quart bottles, atleast 10 gallons of oil will be needed.

Hence the tank of 12 gallons should be used since it has more than 10 gallons of oil.

The two gallon one does not have enough oil.

Option B that means the second option is correct.

The result of the addition of complex numbers 3+i and 2 - 3i will be 5-2i as the rule says "to add or subtract two complex numbers, just add or subtract the corresponding real and imaginary parts.".

Every complex number can be expressed in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element denoted I also known as the imaginary unit, and satisfying the equation i² = -1.

The complex plane in mathematics is the plane made up of complex numbers, with real and imaginary numbers making up the x-axis (also known as the real axis) and the y-axis (also known as the imaginary axis) of the Cartesian coordinate system.

Here,

To add the complex numbers,

To add or subtract two complex numbers, just add or subtract the corresponding real and imaginary parts.

Point C represents √11 on number line

A number line is a visual depiction of numbers on a straight line in mathematics. A number line's numerals are arranged in a sequential manner at equal intervals along its length. It is often displayed horizontally and can extend indefinitely in any direction. A number line is exactly what it sounds like—a horizontal, straight line with numbers spaced evenly apart throughout its length. Since it's not a ruler, the distance between each number is irrelevant; instead, the numbers on the line specify how it should be used.

The x and y intercepts of the given graph of the function are 3/2 and -1 respectively.

Intercepts of the line

The point where the line or curve crosses the axis of the graph is called intercept. If a point crosses the x-axis, then it is called the x-intercept. If a point crosses the y-axis, then it is called the y-intercept.

Given equation of the line:

y = (2/3)x - 1

To find the y -intercept, putting x = 0, we get,

y = (2/3)*0 - 1

y = 0 - 1

y = -1

Hence, the y - intercept is -1.

To find the x -intercept, putting y = 0, we get,

0 = (2/3)x - 1

1 = (2/3)x

x = 3/2

Hence, the x - intercept is 3/2.

Notice that in two steps we can solve the problem.

2) Thus the answer is

If the cafeteria ordered 400 paper plates. They used 226 at breakfast. They bought 100 more. Then, they used some plates for lunch. Now there are 78 plates. The number of  plates that was used at lunch is 196.

Given :

Paper plates ordered = 400 plates

Plates used for breakfast = 226

Additional plate bought = 100

Plate used for lunch = ?

Hence,

Let calculate the plate left after breakfast

Number of plates = Paper plates ordered - Plates used for breakfast

Number of plates = 400 plates - 226 plates

Number of plates = 174 plates

Now let determine the plates that were used for lunch

Pates used for lunch :

Pates used for lunch = (174 + 100) -78

Pates used for lunch = 274 -78

Pates used for lunch = 196 plates

Therefore we can conclude that the number of  plates that was used at lunch is 196 plates .

the area of the pie that Carol will bake will be equal to 249.51 inches².

We are given the circumference of the pie as = 56 inches.

As pie is in the shape of a circle, we will use the formula for circumference to find the radius of the circle.

2 π r = 56 inches

2 × 22 / 7 × r = 56

r = 56 × 7 / ( 22 × 2)

r = 8.91 inches.

Area of circle is given by:

π r²

Substituting the values in the formula, we get that

A = 22 / 7 (8.91)²
