can someone help me with part A please??

Answer:

The answer is option c

Step-by-step explanation:

Product means we have to multiply

[tex](3x - 4y) \times ( - 2x + 5y - 6) \\ 3x( - 2x + 5y - 6) - 4y( - 2x + 5y - 6) \\ - 6x {}^{2} + 15xy - 18x + 8xy - 20y { }^{2} + 24[/tex]

You then group like terms

[tex] - 6x {}^{2} + 15xy + 18xy - 20y {}^{2} + 24 \\ 6x {}^{2} + 23xy - 20y {}^{2} + 24[/tex]

And there's your answer

Let's focus on the figure on the left.

For any quadrilateral, the angles always add up to 360. We'll use this to find x.

105+80+75+x = 360

260+x = 360

x = 360-260

x = 100

Now notice that the pair of adjacent angles 105 and 80 add up to 105+80 = 185, which is not 180. Similarly, the adjacent angles 80 and 75 add to 155 which is not 180.

This is enough to show that we don't have any parallel lines here. If we did have parallel lines, then adjacent angles would add to 180.

Since none of the lines are parallel, this figure is not a trapezoid

Any trapezoid has exactly one pair of parallel lines.

-------------------------------------------------------------------------------------

Move onto the figure on the right

We'll follow the same ideas mentioned in the last section.

x+110+92+88 = 360

x+290 = 360

x = 360-290

x = 70

Note how the adjacent angles 70 and 110 add to 70+110 = 180. This shows they are supplementary angles and that we do have a set of parallel lines (top and bottom). In contrast, the angles 110 and 92 do not add to 180, so that helps us see we only have one pair of parallel lines.

Therefore, the figure is a trapezoid

Step-by-step explanation:

[tex]\sqrt{2} = 1,414213562 = 1,41\\[/tex]     ( with calculator )

[tex]\sqrt{3} = 1,732050808 = 1,73[/tex]     ( with calculator )

Sow , you need 2 irrationale numbers between 1,41 and 1,73

What is a irrationale number ?

Irrational number, any real number that cannot be expressed as the quotient of two integers. ... For example, there is no number among integers and fractions that equals the square root of 2.

An example : 1.234343 , [tex]\sqrt{9\\}[/tex] , π ...

In the file you can find some more info.

Sow we can say 1,583909 and 1,683738 is a Irrationale number between

1,41 and 1,73 = between [tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex]

Answer:

81x^2 sq cm

Step-by-step explanation:

Area formula: length × width

Squares are the same size on all 4 sides, which means because 1 side is 9x cm, all other sides will also be 9x cm.

Area: 9x cm × 9x cm = 81x^2 cm^2

sq = ^2

Answer: 54

Step-by-step explanation:

Total votes: 240

Votes for the winner: x

Votes for candidate 1: x - 8

Votes for candidate 2: x - 13

Votes for candidate 3: x - 15

Equation to find the amount of votes of the winner (x) is:

240 = x +  x - 8 + x - 13 + x - 15

Combine x and x to get 2x.

240=2x−8+x−13+x−15

Combine 2x and x to get 3x.

240=3x−8−13+x−15

Subtract 13 from −8 to get −21.

240=3x−21+x−15

Combine 3x and x to get 4x.

240=4x−21−15

Subtract 15 from −21 to get −36.

240=4x−36

Swap sides so that all variable terms are on the left hand side.

4x−36=240

Add 36 to both sides.

4x=240+36

Add 240 and 36 to get 276.

4x=276

Divide both sides by 4.

x= 4/276  

Divide 276 by 4 to get 69.

x=69

Votes for the winner: 69

Votes for candidate 1: 69 - 8 = 61

Votes for candidate 2: 69 - 13 = 56

Votes for candidate 3: 69 - 15 = 54

The candidate that had the lowest number of votes received 54 votes.

Step-by-step explanation:

The zero is the value of x where the line crosses the x- axis

The line crosses the x- axis at x = - 5 ← zero

Answer:

-5

Step-by-step explanation:

The zero of a function is the x-value of the location where the function intersects the x-axis.

Here I read at (-5,0), the function intersects the x-axis, so the zero of the functiion is x = -5

Answer:

6580 approx

Step-by-step explanation:

Given data

Population= 5000

Rate= 4%

Time = 7years

We are going to apply the compound interest formula

A=P(1+r)^t

substitute

A= 5000(1+0.04)^7

A= 5000(1.04)^7

A=5000*1.3159

A= 6579.5

Hence the population after 7 years is 6580 approx

Answer:

yes you are

Step-by-step explanation:

Answer:

5 is 35 and 6 is 50

Step-by-step explanation:

To solve 5, you need to know how many degrees is the line, which is 180 because lines are 180 degrees. You then subtract 110 from 180 which equals to 70. What you have left now is 2k. A number times 2 will equal to 70, so k=35.

For 6, if you ever see two lines intersecting each other, it means that it is 360 degrees. We already have one angle, which is 120. The other angle is d+70 degrees, and any angle that is reflecting the other angle will have the same value. So, d equals 50

Answer:

375

Step-by-step explanation:

Lily paid $750 each month for 36 months to pay off her car loan.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the amount that Lily paid each month, we can divide the total cost of the car by the number of monthly payments:

So,

Amount paid each month

= Total cost / Number of payments

In this case,

The total cost is $13,500 and the number of payments is 36:

Amount paid each month = $13,500 / 36

We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor of 13,500 and 36, which is 18:

Amount paid each month = $750

Therefore,

Lily paid $750 each month for 36 months to pay off her car loan.

Answer:

x = - [tex]\frac{3}{2}[/tex], x = 3

Step-by-step explanation:

To find the zeros let p(x) = 0 , that is

2x² - 3x - 9 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 9 = - 18 and sum = - 3

The factors are - 6 and + 3

Use these factors to split the x- term

2x² - 6x + 3x - 9 = 0 ( factor the first/second and third/fourth terms)

2x(x - 3) + 3(x - 3) = 0 ← factor out (x - 3) from each term

(x - 3)(2x + 3) = 0

Equate each factor to zero and solve for x

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]

x - 3 = 0 ⇒ x = 3

Answer:

B

Step-by-step explanation:

The 45 45 90 triangle means that the hypotenuse is just one of the two legs multiplied by rad2. This means that leg s is 10.

The length of the leg is 10.

Option B is the correct answer.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Sin 45 = Opposite face to angle 45/ Hypotenuse

1/√2 = s / 10√2

s = 10√2 / √2

s = 10

Thus,

The length of the leg is 10.

I'll do the first one (on the left) to get you started.

Pick any two rows you want from the table. I'll pick the first and third rows.

These rows say that (2,-1) and (4,4) are points on the line.

Use the slope formula to get...

m = (y2-y1)/(x2-x1)

m = (4-(-1))/(4-2)

m = (4+1)/(4-2)

m = 5/2 is the slope

Answer:

4 1/12 yards of fabric left.

Step-by-step explanation:

First things first: convert the mixed numbers so they have the same denominator

The least common multiple of 4 and 3 is 12, so the common denominator will be 12.

So Jenna has 10 9/12, and uses 6 8/12.

Now subtract:

10 9/12 - 6 8/12 = 4 1/12

So there is 4 1/12 yards of fabric left.
