Answer:

Step-by-step explanation:

Put x = 5 and y = 7 to the equation ax - 2y = 1 and solve for a:

(a)(5) - (2)(7) = 1

5a - 14 = 1       add 14 to both sides

5a - 14 + 14 = 1 + 14

5a = 15        divide both sides by 5

5a : 5 = 15 : 5

a = 3

The only correct statement that identifies the right angle is:

Option A: ∠DEF is a right angle

To identify the true statements of the diagram, we will need to look at each of the options to get:

Option A: ∠DEF is a right angle:

We see that the line FA is a straight line and we also see that the line DE is perpendicular to FA and as such we can say that:

∠DEF = ∠DEA = 90°

Option B: m∠DEA = m∠FEC:

This is not true because we can clearly see that m∠DEA is a right angle while  m∠FEC is an acute angle.

Option C: m∠BEA = m∠BEC:

To fill a rectangular prism with dimensions 9in. by 4in. by 1.5in. using half-inch cubes, you need to divide the volume of the prism (54in.^3) by the volume of a cube (0.125in.^3), resulting in 432 cubes needed.

To determine how many half-inch cubes are needed to fill the rectangular prism, we must first calculate the volume of the prism and then the volume of a single cube. Next, we divide the volume of the prism by the volume of a cube to find the number of cubes needed.

Calculating the Volume of the Rectangular Prism

The volume of a rectangular prism is found by multiplying its length by its width by its height. Volume of the prism = length × width × height = 9in. × 4in. × 1.5in. = 54in.3.

Calculating the Volume of a Cube

The volume of a cube is found by raising the length of an edge to the third power. Volume of a cube = edge length3 = (0.5in.)3 = 0.125in.3.

Number of Cubes Needed

To find the number of cubes needed to fill the prism, divide the volume of the prism by the volume of a cube. Number of cubes needed = Volume of the prism / Volume of a cube = 54in.3 / 0.125in.3 = 432.

Therefore, 432 half-inch cubes are needed to fill the rectangular prism.

Replace x with  [tex]y^{1/4}[/tex]

Step-by-step explanation:

The general  form of a quadratic equation is  [tex]ax^{2}[/tex] + bx + c.

To  find a substitution  we have to think of a way of substituting ‘x’ to make it have a power of 2,

Here, we will use [tex]y^{1/4}[/tex]  

[tex]x^{8}[/tex] - [tex]3x^{4}[/tex] +2 = 0

let x = [tex]y^{1/4}[/tex]

so it gives

([tex]y^{1/4}[/tex])^8 – 3( [tex]y^{1/4}[/tex] )^4 +2 = 0

[tex]y^{2}[/tex] – 3y + 2 = 0

Solving the equation

[tex]y^{2}[/tex]  - 2y – y + 2 =0

([tex]y^{2}[/tex] – 2y) -1(y – 2) = 0

y(y - 2) -1(y - 2) = 0

(y-1) (y-2)

:- y = 1 or y = 2

Since x = [tex]y^{1/4}[/tex]  

When y = 1

X = [tex]1^{1/4}[/tex]

X = [tex]4\sqrt{1}[/tex]

X = 1

and when  y = 2

X = [tex]2^{1/4}[/tex]

X = [tex]4\sqrt{2}[/tex]

Valerie's monthly income tax payment is $235.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, Based on Valerie's annual salary of $24,000, her monthly salary would be,

$24,000 / 12

$2,000

Hence, To calculate her income tax, we first need to determine how much of her earnings are over $944.

⇒ $2,000 - $944

⇒ $1,056

Thus, Valerie's earnings over $944 are $1,056.

Next, we'll calculate the income tax on that amount.

$1,056 x 0.15 = $158.40

So Valerie pays $158.40 in income tax each month.

Additionally, she pays a fixed amount of $76.60 each month, which brings her monthly total to:

⇒ $158.40 + $76.60 = $235.

Therefore, Valerie's monthly income tax payment is $235.

Hey there!

Let's start by solving for x.

Take the first equation, y = -3x - 7, and substitute in the second equation, y = x + 9, for y.

We now have:

x + 9 = -3x - 7

Add 3x to both sides.

4x + 9 = -7

Subtract 9 from both sides.

4x = -16

Divide each side by 4.

x = -4

Let's use the second equation, y = x + 9, to solve for x.

Put in the value we just solved for.

We now have:

y = -4 + 9

Simplify.

y = 5

Let's check our answer, starting with the first equation, y = -3x - 7.

Put in the values for x and y.

5 = -3(-4) - 7

5 = 12 - 7

5 = 5

Do the same with the second equation, y = x + 9.

5 = -4 + 9

5 = 5

The solution to the system of equations is (5, -4).

Hope this helps!

Answer:

(-4, 5)

Step-by-step explanation:

Since y = -3x - 7 in the first equation, substitute y of the second equation with -3x - 7:

-3x - 7 = x + 9

Subtract x from both sides. Add 7 to both sides.

-4x = 16

Divide both sides by -4.

x = -4

Now, substitute -4 for x in the second equation.

y = -4 + 9

y = 5

The solution is:

x = -4; y = 5

Final answer:

Using the GCF of 10 and 15, which is 5, we cross-cancel the fractions 5/15 and 5/10 to reduce them to 1/3 and 1/2 respectively. Multiplying these reduced fractions, we obtain the final answer of 1/6.

Explanation:

To solve the fraction 5/15 × 5/10, we first identify the Greatest Common Factor (GCF) of the numerators and denominators. The GCF of 10 and 15 is 5. Using this GCF, we cross-cancel to reduce the fractions before multiplying.

Firstly, we divide both 10 and 15 by the GCF, which gives us:

10 ÷ 5 = 2

15 ÷ 5 = 3

Applying cross-cancellation to the original expression, we get:

(5 ÷ 5) / (15 ÷ 5) × (5 ÷ 5) / (10 ÷ 5)

1/3 × 1/2

Multiplying these reduced fractions gives us:

1/3 × 1/2 = 1/6

Thus, the result of multiplying 5/15 by 5/10, after cross-cancelling the common factors, is 1/6.

y=mx+b where m is the slope and b is the y intercept.

Final answer:

Linear equations are written as y = mx + b or y = a + bx, where 'm' or 'b' in the first form and 'b' in the second represents the slope and 'b' in the first form and 'a' in the second represents the y-intercept. The equation can model relationships where 'y' changes at a constant rate with 'x', forming a straight line graph.

Explanation:

Understanding Linear Equations

Linear equations represent relationships between variables that result in a straight line when graphed on a Cartesian plane. These equations are typically written in the form y = mx + b or in a statistical context as y = a + bx. Here, 'y' is the dependent variable and 'x' is the independent variable. The constant 'm' or 'b' in the first equation and 'b' in the second represents the slope of the line, which indicates the rate of change of 'y' with respect to 'x'. The constant 'b' in the first equation and 'a' in the second equation represents the y-intercept, which is the point where the line crosses the y-axis, at which point 'x' equals zero.

Graphically, the slope denotes the steepness and the direction of the line, while the y-intercept gives us the starting point of the line on the graph. For example, in the equation y = 6x + 8, the slope is 6 and the y-intercept is 8. This means that for every one unit increase in 'x', 'y' will increase by 6 units, and when 'x' is 0, the value of 'y' is 8.

Different scenarios can be modeled using linear equations, such as calculating the total number of hours required based on the square footage (y = x + 4), determining the total payment based on the number of students (y = 100(x) + 2,000), or finding the total cost of attendance over a number of years (y = 3,000(x) + 500).

The linear equation is also applicable in understanding real-world issues, such as tracking the number of flu cases over the years, where the number of cases depends on the year.

Final answer:

It will take 72 minutes to fill the pool using only 3 taps.

Explanation:

To find out how many minutes it will take to fill the pool using only 3 taps, we can set up a proportion.

If it takes 120 minutes to fill the pool using 5 taps, then the rate at which water flows from the taps is 1 pool/120 minutes/tap.

Using this rate, we can set up the proportion:

5 taps / 3 taps = 120 minutes / x minutes

Cross-multiplying and solving for x gives us:

x = (3 taps * 120 minutes) / 5 taps = 72 minutes

So, it will take 72 minutes to fill the pool using only 3 taps.

Step-by-step explanation:  

2x-7+x-11= 3x-11

2x+x-7-11=3x-11

3x-18=3x-11

3x-18+11=3x

3x-7-3x=0

-7=0

Impossible

We combined like terms on both sides to solve 2x - 7 + x - 11 = 3x - 11. However, this led to the false equation -18 = -11, indicating a potential error in the given problem.

The equation to solve is 2x - 7 + x - 11 = 3x - 11. The goal is to find the value of x.

The first step is to combine like terms on the left side of the equation. We combine 2x and x to get 3x and -7 and -11 to get -18. So, the problem becomes 3x - 18 = 3x - 11.

From here, we subtract 3x from both sides to isolate x on one side. This gives us -18 = -11. This equation is, however, incorrect.

This discrepancy could arise from a mistake in the original problem, notably, the content loaded 2x - 7 + x - 11 = 3x - 11.

The answer is (D) ⇒ a = 11.71 , b = 15.56

Step-by-step explanation:

* In ΔABC

∵ m∠A = 45°

∵ m∠B = 110°

∴ m∠C = 180 - 45 - 110 = 25°

By using the sin Rule

∵ a/sin(A) = b/sin(B) = c/sin(C)

∵ c = 7

∴ a/sin(45) = b/sin(110) = 7/sin(25)

∴ a = (7 × sin(45)) ÷ sin(25) = 11.71

∴ b = (7 × sin(110)) ÷ sin(25) = 15.56

Let x and y be the two numbers whose difference is 6 and whose sum is also 6.

We can write it in the form of the equation:

[tex]x - y = 6\\x+y =6\\\\\text{Adding the two equations}\\(x-y) + (x+y) = 12\\2x =12\\x = 6\\\\\text{Putting this value of x in one of the equations}\\6 + y = 6\\y = 0[/tex]

Hence, the only possible numbers are 6 and 0.

It is possible as the numbers are 0 and 6.

Let the numbers be a and b.

Based on the question, the equation to solve the question will be:

a - b = 6 ........ i

a + b = 6 ........ ii

From equation i, a = 6 + b

Put the above into equation ii

a + b = 6

(6 + b) + b = 6

6 + 2b = 6

2b = 6 - 6.

2b = 0

b = 0/2

b = 0

Therefore, the value of a will be:

a = 6-0 = 6.
