b)-3x-2+6x=3x+4-2
c)-4x-2+3x=-1x+5
d)6x+3x-54=-9x-54

Answer: The answer is B

Step-by-step explanation:

The transformation applied to A'B'C'D' is rotating the quadrilateral by 90 degrees counterclockwise about the origin, then translating 3 units left

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the quadrilateral be represented as ABCD

Now , the transformed quadrilateral is A'B'C'D'

And , coordinates are A ( 1 , 5 ) , B ( 1 , 9 ) , C ( 5 , 9 ) and D ( 5 , 5 )

Now , the square is rotated by 90° counterclockwise and translated 3 units to the left

So , 90° counterclockwise rotation: (x,y) becomes (-y,x)

The coordinates are A' ( -5 - 3 , 1 ) , B' ( -9 - 3 , 1 ) , C' ( -9 - 3 , 5 ) and D' ( -5 - 3  , 5 )

The coordinates are A' ( -8 , 1 ) , B' ( -12 , 1 ) , C' ( -12 , 5 ) and D' ( -8  , 5 )

Hence , the quadrilateral is rotated by 90° counterclockwise and translated 3 units to the left

Answer:

quadratic

Step-by-step explanation:

Answer:

a. 0.25 km

Step-by-step explanation:

For an arithmetic sequence, the sum of all terms up to term n is

sum = n/2[2a + (n - 1)d]

We are given:

sum of first 6 terms = 18.75

sum of the first 10 terms = 36.25

6/2[2a + (6 - 1)d] = 18.75

10/2[2a + (10 - 1)d] = 36.25

3(2a + 5d) = 18.75

5(2a + 9d) = 36.25

2a + 5d = 6.25

2a + 9d = 7.25

4d = 1

d = 0.25

2a + 5(0.25) = 6.25

2a = 5

a = 2.5

The common difference is 0.25 km.

Answer:

Any negative number or decimal, for example, -1, or 0.5

Step-by-step explanation:

-1 multiplied by 40 turns into -40, which is less that 40

0.5 times 40 is 20, which is less that 40

For the given condition, the product should be less than 40 the value of x must be less than 1.

Given that,

40 is multiplied by a number to identify a number that will give a product less than 40, the number is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Let the number be x,

40 is multiplied by a number to identify a number that will give a product less than 40,
40 * x < 40
Dividing both sides by 40,

x < 40 / 40

x < 1

Thus, for the given condition, the product should be less than 40 the value of x must be less than 1.

Answer:

the answer is 7 candy bars

Step-by-step explanation:

theres two ways of doing this the equation way and the common sense way m(x) basically just means y so y= 3x -20 we can set y to 0 so 0 = 3x -20 next add 20 to the other side 20 = 3x then divide both sides by 3 you get x= 6.666 but you cant sell .666 of a chocolate bar so round to 7 and thats your answer. the other strategy is saying hey i get $3 per candy bar what number would put be at 21 since 21-20= $1 and we say 7*3 = 21 so 7 is the answer.

Answer:

Evan purchased 7 frozen dinners and 9 cans of soup.

Step-by-step explanation:

Since Evan went to the grocery store and purchased cans of soup and frozen dinners, and each can of soup has 150 mg of sodium and each frozen dinner has 550 mg of sodium, and Evan purchased a total of 16 cans of soup and frozen dinners which collectively contain 5200 mg of sodium, to determine the number of cans of soup purchased and the number of frozen dinners purchased the following calculation must be performed:

16 x 550 + 0 x 150 = 8800

8800 - 5200 = 3600

550 - 150 = 400

3600/400 = 9

7 x 550 + 9 x 150 = X

5200 = X

Therefore, Evan purchased 7 frozen dinners and 9 cans of soup.

Since, A city council poll revealed that 56% of the citizens want a fireworks display for the upcoming 4th of July celebration.

Hence, The number of people for the cities people want a fireworks display for the 4th of July is,

⇒ 56% of 9,525

⇒ 56/100 × 9525

⇒ 5,334

Thus, The number of people for the cities people want a fireworks display for the 4th of July = 5,334

Answer:

Step-by-step explanation:

Answer:

3x + 3 = 54 degrees

x + 2 = 19 degrees

Step-by-step explanation:

Since, both angles add up to 73 degrees, write these equation

X + 2 + 3x + 3 = 73

4x + 5 = 73

4x = 73 - 5

4x = 68

4x/4 = 68/4

x = 17

Substitute the value of x to x + 2 and 3x + 3

x + 2

17 + 2 = 19°

3x + 3

3(17) + 3

51 + 3 = 54°

Now add them

42 is an area

Step-by-step explanation:

The area of a trapezium.

= 1/2 x (a + b) x h

Where a and b are the two parallel sides.

The area of a semicircle.

Area of a circle = πr²

Area of the semicircle = 1/2 x πr²

The area of20mm 14mm 32mm is 521 mm²

A circle is a two-dimensional figure with a radius and circumference of 2 x pi x r.

The area of a circle is given as:

Area = πr²

We have,

Figure:

The figure is a combination of a trapezium and a semicircle.

The area of a trapezium.

= 1/2 x (a + b) x h

Where a and b are the two parallel sides.

a = 32 mm

b = 20 mm

h = 14mm

= 1/2 x (32 + 20) x 14

= 52 x 7

= 364 mm²

The area of a semicircle.

Area of a circle = πr²

Area of the semicircle = 1/2 x πr²

Diameter = 20 mm

Radius = 20 / 2 = 10 mm

= 1/2 x π x 10²

= 1/2 x 3.14 x 10 x 10

= 3.14 x 10 x 5

= 157 mm²

Now,

The area of the figure.

= area of trapezium + area of semicircle

= 364 + 157

= 521 mm²

Thus,

The area of20mm 14mm 32mm is 521 mm²

Answer:

x = 63

Step-by-step explanation:

This is a right angle, and we know that there are 90 total degrees in a right angle. Because of this information, we know that the degrees of both angles, added together, should come out to 90. This reasoning looks like this:

[tex]25+(x+2)=90[/tex]

Now, it's much easier to solve for x. I'll start by removing the parentheses and combining like terms.

[tex]25+x+2=90\\25+2+x=90\\27+x=90[/tex]

Now, let's remove 27 both sides to isolate x and figure out what it's equal to.

[tex]27+x=90\\x = 63[/tex]

So, the measure of x is 63 degrees. We can make sure this is correct by using our equation:

Is [tex]25+(63+2)=90[/tex]? Yes, because 63 + 2 is equal to 65, and 65 plus 25 is equal to 90. So our answer is correct.

If you need any more help, let me know! :)

Answer:

x = 63°

Step-by-step explanation:

(x + 2) + 25 = 90

x + 2 = 90 - 25

x + 2 = 65

x = 65 - 2

x = 63°

(x + 2) + 25 = 90

(63 + 2) + 25 = 90

65 + 25 = 90

90 = 90

If the output and input of a linear equation are proportional, the graph of the equation cross the x-axis at (0, 0).

In any function, the amount of one quantity is dependent on the amount of another. All proportional functions use a rate in the same way. We call the rate the constant of variation, or the constant of proportionality. It’s a constant because this number does not change within the function. Because the input and output are linked by a constant, changes in the independent variable cause the dependent variable to change in a proportional, steady way.

y ∝ x

⇒ y = kx

where k is the constant of proportionality.

For the graph of this function to cross x axis, y = 0

When y = 0  and k is some non zero constant value, x = 0

Thus, the coordinate at which the graph of the function crosses x axis is (0, 0).
