[tex]4x - 1 - 3(1) - 3( - x) = 10 \\ 4x - 1 - 3 + 3x = 10 \\ 4x + 3x - 1 - 3 = 10 \\ 7x - 4 = 10 \\ 7x = 10 + 4 \\ 7x = 14 \\ \frac{7x}{7} = \frac{14}{7} \\ x = 2[/tex]

ATTACHED IS THE SOLUTION

Answer:

E. [tex] a = 5-2b [/tex]

Step-by-step explanation:

how to find the value of a, we need to subtract 2b from both side to single out the variable

a + 2b = 5

subtract 2b from both sides

a + 2b - 2b = 5 - 2b

a = 5 - 2b

Therefore, Option E is the correct answer

A fraction, which also symbolizes a piece of a whole, is a mathematical symbol for any number of equal parts. A fraction, such as one-half, eight-fifths, and three-quarters, denotes the number of components of a specific size when used in conversational English.

By converting the incorrect fraction, produce an appropriate fraction.

Jocab travels 5 miles in 1 1/2 hours; therefore, 1 1/2 hours is 3/2 hours in minutes, or 3/2 x 60 minutes.

Robert: Three miles in seventy-five minutes = forty-five minutes.

If Robert runs 3 miles in 45 minutes, he completes 6 miles, as opposed to Jocab's 5 miles in 90 minutes.

Robert thus moved more quickly than Jocab.

The correct point slope form is  y - 1 = 2 ( x - 9).

What is the point slope form?

The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

The amount Bennet will have when he turns 18 will be equal to $3020.

Compound interest is the type of interest charged by banks or institutions on individuals in which the amount after 1 year becomes the principle for the next year. It can be calculated daily, monthly or yearly etc. The formula for compound interest compounded daily will be

A = P(1 + r/n) ^nt, where A is the amount, P is the principle, which is equal to $2000, r is rate of interest which is 3.2% or 0.032, n is compounding frequency which is equal to 365 and t is the time which is equal to 13 years. Now, the amount will be

A = 2000(1 + 0.032/365) ^365×13

A = 2000(1.51)

A = $3020 which is the required amount.

The term that best describe the quadrilateral formed by the points A(2, 3), B(4, 6), C(8, 9), and D(5, 5) is option D. Kite

Quadrilateral:

A quadrilateral is the closed shape and a type of polygon that has four sides, four vertices and four angles.

The distance of the tow points can be calculated by using the formula,

d = √(x₂ - x₁)² + (y₂ - y₁)²

Where

(x₁, y₁) and (x₂, y₂) represents the coordinates of the two endpoints on the side

Given,

Here we have the points  A(2, 3), B(4, 6), C(8, 9), and D(5, 5) that forms the quadrilateral.

And we need to find the shape of the quadrilateral.

Let us consider the coordinates of the vertices of the quadrilateral are A(2, 3), B(4, 6), C(8, 9), and D(5, 5),

To find its shape, we have to calculate the length of the sides of the quadrilateral can be found using the distance formula.

For side AB, we have the distance of

d1 = √(6 - 3)² + (4  - 2)²

d1 = √13

For side BC, we have the distance of

d2 = √(9 - 6)² + (8 - 4)²

d2 = √9 + 16

d2 = √25

d2 = 5

Now we have to take side CD,

d3 = √(5 - 9)² + (5 - 8)²

d3 = √16 + 9

d3 = √25

d3 = 5

Finally, side DA, we have;

d1 = √(3 - 5)² + (2  - 5)²

d1 = √13

Therefore, the given quadrilateral has two pairs of equal adjacent sides and the angles are equal at the meeting point of the two squares, it is best described as a kite.

Answer:

x = 5

Step-by-step explanation:

Take your starting equation:

5x - 6 = 2x + 9

Your first step should be to isolate the variable, X, by having it on only one side of the equation. This can be done by subtracting one of the X values (either 5x or 2x) from either side, but I recommend the side with 2x since it's a smaller value and won't result in a negative.

(This is the right side of the equation)

2x + 9

- 2x

= 9

We need to do the same thing on the other side of the equation too, to balance both sides:

(This is the left side of the equation)

5x - 6

- 2x

= 3x - 6

This is our equation now:

3x - 6 = 9

The next step is to isolate X further by removing any constants (regular numbers) from the side with X. Since the constant on that side is -6, we need to add 6 to that side so that it's cancelled out, and do the same on the other side to balance.

(This is the left side of the equation)

3x - 6

+ 6

= 3x

And now for the other side:

(This is the right side of the equation)

9

+ 6

= 15

This is our current equation:

3x = 15

The final step is to get X completely isolated. X is being multiplied by 3, so we need to divide both sides of the equation by 3 to finally get the value of X.

(This is the left side of the equation)

3x

÷ 3

= x

And now for the other side:

(This is the right side of the equation)

15

÷ 3

= 5

Our final equation:

x = 5

We can check our answer by taking the final X value, 5, and inserting it into our beginning equation.

This is the beginning equation, as a reminder:

5x - 6 = 2x + 9

Replace all instances of X with its value, 5:

(5 · 5) - 6 = (2 · 5) + 9

After simplifying, the result is:

19 = 19, which means the X value is correct.

The equation of the given line in the diagram above is expressed as: b. y = 2/3x.

For a line that passes through the origin (0, 0) of a graph, the equation that represents the line can be written in slope-intercept form as y = mx, where the slope of the line is represented as m.

The y-intercept of this type of line is zero, that is why we have the equation expressed as y = mx. Where the y-intercept is not equal to zero, the equation of the line would be expressed as y = mx + b, where b is the y-intercept and m is the slope of the line.

Find the slope of the line using two points on the line, (0, 0) and (3, 2):

Slope of the line (m) = (2 - 0)/(3 - 0)

Slope of the line (m) = 2/3.

To write the equation of the line, substitute m = 2/3 into y = mx:

y = 2/3x.

The equation is: B. y = 2/3x.

⇒ BC = 5 miles and AC = 9 miles

We need to find the distance from Jessica's school to her house in miles.

i.e., we need to find AB

Using Pythagoras theorem,

AC² = AB² + BC²
