Answer:

x = -4

Step-by-step explanation:

3(x-5) becomes 3x-15

5x-(3-x) becomes 6x-3

3x - 15 = 6x - 3

    + 15        + 15

3x = 6x + 12

-6x  -6x

-3x = 12

    divide -3 on both sides

X = - 4

Answer:

x = -4.

Step-by-step explanation:

3(x-5) = 5x-(3-x)

3x - 15 = 5x - 3 + x

3x - 5x - x = -3 + 15

-3x = 12

x = -4.

The coordinates of the second end point of the line is (8, -12).

For the given question;

The end point of the line segment is (0,0).

The mid-point of the line segment is at  (4,-6).

Thus,

(x₁, y₁) = (0,0)

(x₂, y₂) = ?

(xₐ, yₐ) = (4,-6)

Thus, the formula for finding the mid point is;

xₐ = (x₁ + x₂)/2

Put the values;

4 = (0 + x₂)/2

On simplification;

x₂ = 8.

For y coordinate;

Thus, the formula for finding the mid point is;

yₐ = (y₁ + y₂)/2

Put the values;

-6 = (0 + y₂)/2

On simplification;

x₂ = -12

Thus, the coordinates of the second end point of the line is (8, -12).

Step-by-step explanation:

A number squared cannot be negative. It is a trick question.

the Algebraic representation of the expression "product of 2 and the cube of a number" is 2x³

Algebra is the system for computation using letters or other symbols to represent numbers, with rules for manipulating these symbols.

The product of 2 and the cube of a number

So,

product of 2 and the cube of a number

= 2 × x³

= 2x³

For instance, if x = 2

2x³

= 2×(2)³

= 2 × (2 × 2 × 2)

= 2 × 8

= 16

Therefore, the expression "product of 2 and the cube of a number" can be written as 2x³

What is mean by proportion?

A proportion is a fraction of a total amount, in which two ratios are set equal to each other.

Given that;

For incomes from $38,701 up to $82,500, you need to pay 22% in taxes.

And, No federal taxes up to $9,525, 12% for income from $9,526 up to $38,700, 22% for income from $38,701 up to $82,500.

Now,

An income of $57,890 is in this range, hence the amount paid is given by;

Amount paid = 57890 x 22%

                    = 57890 x 0.22

                    = $12,735.8.

So, Paid amount for the tax = $12,735.8

Using properties of exponents, the simplified expression for 5³ x 5^(-5) is given by:

A. 1/(5²).

The exponent property applied to multiply the terms with the same base but different exponents is that we keep the bases and then add the exponents.

For this problem, the expression is given as follows:

5³ x 5^(-5)

Hence:

Adding the exponents, we have that:

3 + (- 5) = 3 - 5 = -2.

Hence the simplified expression is:

5³ x 5^(-5) = 5^(-2).

When a number has a negative exponent, we can move it to the denominator, then the exponent becomes positive, hence:

5^(-2) = (1/5)² = 1/5² = 1/25.

Meaning that option A is correct.

The expression in this problem is 5³ x 5^(-5), and the correct options are given by the image at the end of the answer.

After 2.57 hours, the distance between Steve and Elsie will be 25 miles.

So, let t (hours) represent the amount of time Elsie needs to travel before they are 25 miles apart.

Steve takes longer because he is 2 hours earlier, so his time is t + 2.

So, according to the formula the distance between Steve and Elsie will be:

Solve for t as follows:

[tex]\begin{aligned}&(2(t+2))^2+(2.5 t)^2=25^2=625 \\&4(t+2)^2+6.25 t^2=625 \\&4\left(t^2+4 t+4\right)+6.25 t^2=625 \\&10.25 t^2+16 t-609=0 \\&t=\frac{-b \pm \sqrt{t^2-4 a x}}{2 a} \\&t=\frac{-16 \pm \sqrt{(16)^2-4 *(10.25) *(-109)}}{2 *(10.25)} \\&t=\frac{-16 \pm 68.74}{20.5}\end{aligned}[/tex]
