Determine the relationship between given lines

(a)

[tex]y = -\frac{2}{5}x + 3[/tex]

and

[tex]y = \frac{2}{5}x + 7[/tex]

An equation written in form: [tex]y=mx + b[/tex] has the slope:

[tex]m \to slope[/tex]

So, in both equations:

[tex]m_1 = -\frac{2}{5}[/tex]

[tex]m_2 = \frac{2}{5}[/tex]

For both lines to be parallel

[tex]m_1 = m_2[/tex]

This is false in this case, because:

[tex]-\frac{2}{5} \ne \frac{2}{5}[/tex]

For both lines to be perpendicular

[tex]m_1 * m_2 = -1[/tex]

This is false in this case, because:

[tex]-\frac{2}{5} * \frac{2}{5} \ne -1[/tex]

(b)

[tex]5y + 2x = -10[/tex]

and

[tex]-5x + 2y = 4[/tex]

Write equations in form: [tex]y=mx + b[/tex]

[tex]5y + 2x = -10[/tex]

[tex]5y = -2x +10[/tex]

Divide by 5

[tex]y = -\frac{2}{5}x +2[/tex]

[tex]-5x + 2y = 4[/tex]

[tex]2y = 5x + 4[/tex]

Divide by 2

[tex]y = \frac{5}{2}x + 2[/tex]

In both equations:

[tex]m_1 = -\frac{2}{5}[/tex]

[tex]m_2 = \frac{5}{2}[/tex]

For both lines to be parallel

[tex]m_1 = m_2[/tex]

This is false in this case, because:

[tex]-\frac{2}{5} \ne \frac{5}{2}[/tex]

For both lines to be perpendicular

[tex]m_1 * m_2 = -1[/tex]

This is true in this case, because:

[tex]-\frac{2}{5} * \frac{5}{2} = -1[/tex]

Cancel out 2 and 5

[tex]-1 = -1[/tex]

Answer:

y = -3/2 or -1.5

Step-by-step explanation:

-2/3 + y = -2 1/6

-2 1/6 = -13/6

So, our equation is

-2/3 + y = -13/6

Add 2/3 to both sides

y = -3/2

So, the answer is

y = -3/2 or -1.5

Answer:
Y= -3/2
in decimal form it is -1.5
in mixed number form it is -1 1/2

Therefore , the solution of the given problem of equation comes out to bem² + p² =z².

The Latin word equ has the meaning of equivalent. Many of the English language's changeable terms, including adequate, temperate, and equality, contain Latin roots in their base words. The Latin root word equ enters our lexicon rather easily because both sides of an equation are, by essence, "equal" to one another.

Here,

Given : a triangle of m,p,z of length of right triangle :

Answer:

o, we should add 16 on both sides in order to make it a complete square

Step-by-step explanation:

For making a perfect square we will add 16 on both sides of the given equation.

The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.

Given equation is:-

x² - 8x = 5

x² - 8x + 16  = 5 + 16

x² - 4x -4x + 16  = 5 + 16

x ( x - 4 ) -4 (x - 4 ) = 21

The flowers on the float would be 6.000 flowers. The result is obtained by using fraction multiplication.

Fraction represents the part of a set of objects. It has two parts separated by a dividing line, namely numerator at the top and denominator at the bottom.

For example:

It means one of four parts and two of five parts.

We have four thousand two hundred carnations on the float. It was 7/10 of flowers needed. Find the whole flowers on the float!

The carnations of a set of flowers is 7/10. It is 4200 carnations.

The carnations part is 7 and the whole part of flowers is 10.

Using fraction, the whole flowers would be

The == operator determines if two operands are equivalent in terms of value. The === operator determines if two operands are equivalent in terms of value and datatype.

The assignment operator = is straightforward. The left side operand receives values from the right side operands.

On the other hand, == determines whether or not the values of two operands are equal.

The Python is operator determines if two variables point to the same memory item as opposed to the == operator, which compares the value or equality of two objects. This implies that you should almost always employ the equality operators == and != Difference between == and = in Python.

Step-by-step explanation:

Let’s find the area of the shapes that in the net.

First, we can see two of the triangles have a base of 2 and a height of 13. The formula for surface area of a triangle is bh÷2. (13x2)÷2=13. Since there are two triangles, we multiply 13 by 2 and get 26.

Second, we can see two of the triangles have a base of 10 and a height of 12. (10x12)÷2=60. Since there are two triangles, we multiply 60 by 2 and get 120.

Third, we can see a rectangle has a base of 10 and a height of 2. The formula for surface area of a rectangle is bh. 10x2=20.

Last, we add up all the areas:

Answer:

A.   2w² + 8w

Step-by-step explanation:

rectangle:  A = w(w+4) = w² + 4w

triangle:  A = 1/2(2(w+4)(w)) = 1/2(2w+8)(w) = 1/2(2w²+8w) = w² + 4w

Total Area = w² + 4w + w² + 4w = 2w² + 8w

Answer: The length of each side of the triangle is; 

Equal sides, x = 21.02 = PQ = PR

QR = 28.03

Step-by-step explanation: The trusses made by the manufacturer have the shape of an isoscellestriangle and as such two congruent sides PQ ≅ PR) are equal and QR is the third side whose length is 4/3 of the congruent sides.

The perimeter of each truss is 70ft.

Let the length of each congruent side be x ft.

Therefore,

Perimeter = x + x + (4/3)x

Perimeter, p = 70 = 3.33x

x = 70/3.33

x = 21.02

Therefore, Length of QR is; QR = (4/3) x

QR = (4/3) × 21.02

QR = 28.03

Step-by-step explanation:

The way that you would multiply polynomials is pretty easy. Say we had a binomial and a trinomial and we wanted to multiply them. As an example, we will use (2x + 4) (x^2 + x + 4).

You have to multiply each number with each other number. For example, we would multiply 2x by x^2, 2x by x, and 2x by 4 to get the first part of the bigger equation. These come out to being 2x^3 + 2x^2 + 8x when multiplied and added.

Then, you have to do the same thing for the 4 in the binomial. Multiply 4 by x^2, 4 by x, and 4 by 4 to get the second part of the bigger equation. These come out as 4x^2 + 4x + 16 when added and multiplied.

After both of those are done, simply add the two parts together and simplify.

2x^3 + 2x^2 + 8x + 4x^2 + 4x + 16

2x^3 + 6x^2 + 12x + 16

That is your example answer, and that is how you multiply polynomials.

Answer:

The area of the shaded region is, [tex]24mm^{2}[/tex]

Step-by-step explanation:

First we have to calculate the area of ΔABC and ΔXYZ.

Area of ΔABC = [tex]\frac{1}2}[/tex]×[tex]Base[/tex]×[tex]Height[/tex]

Area of ΔABC = [tex]\frac{1}{2}[/tex]×[tex]5mm[/tex]×[tex]12mm[/tex]

Area of ΔABC =[tex]30mm^{2}[/tex]

and,

Area of ΔXYZ = [tex]\frac{1}{2}[/tex]×[tex]Base[/tex]×[tex]Height[/tex]

Area of ΔXYZ = [tex]\frac{1}{2} X3mmX4mm[/tex]

Area of ΔXYZ = [tex]6mm^{2}[/tex]

Now we have to calculate the area of the shaded region.

Area of the shaded region = Area of ΔABC - Area of ΔXYZ

Area of the shaded region = [tex]30mm^{2} - 6mm^{2}[/tex]

Area of the shaded region = [tex]24mm^{2}[/tex]

Therefore, the area of the shaded region is, [tex]24mm^{2}[/tex]

The effective annual rate of interest if you do not make any payments for a year is 35%.

Compound interest is the addition of interest to the principal sum of a loan or deposit. Mathematically -

[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]

where -

[A] = final amount

[P] = initial principal balance

[r] = interest rate

[n] = number of times interest applied per time period

[t] = number of time periods elapse

Given is that You just bought a new tablet computer for $500, including tax. There are no required payments for six months, but the company does charge 30% annual interest, compounded monthly, on any unpaid balance.

We can write -

A = 500(1 + 0.3/12)¹²⁽¹⁾

A = 500(1 + 0.025)¹²

A = 500 x (1.025)¹²

A = 675

Effective annual interest rate for a year is as follows -

A = 500(1 + r/1)⁽¹⁾⁽¹⁾

675 = 500(1 + r)

1 + r = 675/500

1 + r = 1.35

r = 0.35

r = 35%

Therefore, the effective annual rate of interest if you do not make any payments for a year is 35%.

Answer:

x = 14

Step-by-step explanation:

Vertical angles are congruent ( equal to each other )

If ∠A and ∠B are vertical angles

Then 5x + 2 = 6x - 12

                     ^ ( Note that we just created an equation that we can use to                                   solve for x )

The rest comes down to basic algebra

5x + 2 = 6x - 12

step 1 subtract 5x from each side

5x - 5x cancels out

6x - 5x = x

we now have 2 = x - 12

step 2 add 12 to each side

- 12 + 12 cancels out

2 + 12 = 14

we're left with x = 14
