Answer:

Step-by-step explanation:

23x + xy - y + 3y + 5 - 20x + 6xy = 23x - 20x + xy  + 6xy -y + 3y + 5

                                                     = 3x + 7xy + 2y + 5

Errors:1) The combined coefficients of the x terms should be 3x, not 43x

2) The coefficients of the y terms have been multiplied.

3) The constant was left off.

Answer:

16

Step-by-step explanation:

Apply the arithmetic series formula, with A=4, d=3 and n=5 as n represents the number of terms.

An = A+(n-1)d

This shows that: A5 = 4+ 4(3) = 16.

Fifth term of the arithmetic sequence is 16.

"Arithmetic sequences are ordered sets of numbers that have a common difference between each consecutive term."

Given

First term a1 = 4

Common difference d = 3

n = 5

Formula to find fifth term in the arithmetic sequence

[tex]a_{5} = a_{1} +(n-1)d[/tex]

[tex]a_{5}= 4+(5-1)3[/tex]

[tex]a_{5}= 4+(4)3[/tex]

[tex]a_{5}= 4+12[/tex]

[tex]a_{5}= 16[/tex]

Hence, fifth term of the arithmetic sequence is 16.

Answer:

Below.

Step-by-step explanation:

[tex]y=x^2[/tex] is also [tex]y = x*x[/tex]

It will differ for any x besides 1 and 0 because you're multiplying x by itself, which makes the answer greater.

But, it's the same for 1 and 0 because they equal each other when you square them.

Answer:

d; below; y = −2x + 2

Step-by-step explanation:

the equality  ≤  means left to right that y is equal or less than. We see that 2 is equal or less than 3.

We check the resulting equation also and see that if we +3 it = 1 and if we +2 it equals 0 so we know +2 in answer format can be less than also. But with questions we are measuring the units and +2 is less than +3.

[tex]\fbox{\begin{minipage}{10em}Option C is correct\end{minipage}}[/tex]

Explanation:

A circle whose center is [tex](a, b)[/tex] and radius [tex]r[/tex], has equation:

[tex](x - a)^{2} + (y - b)^{2} = r^{2}[/tex]

The center of circle is  given as origin [tex](0, 0)[/tex], therefore:

[tex]a = 0\\b = 0[/tex]

This circle passes [tex](3, 0)[/tex], then the radius of circle is the distance [tex](d)[/tex] between origin [tex](0, 0)[/tex] and [tex](3, 0)[/tex]

[tex]d = \sqrt{(0 - 3)^{2} + (0 - 0)^{2} } = \sqrt{3^{2} } = 3[/tex]

=> [tex]r = d = 3[/tex]

Substitute [tex]a[/tex], [tex]b[/tex], and [tex]r[/tex] back into original equation:

[tex](x - 0)^{2} + (y - 0)^{2} = 3^{2}[/tex]

or

[tex]x^{2} + y^{2} = 9[/tex]

Answer:

-4,8

Step-by-step explanation:

If vertex A is located at (-1, 2) then the coordinates of A' is

A translation only moves a shape up, down, or from side to side; it has no effect on how it appears. One illustration of a transformation is translation. A transformation is a technique for moving or repositioning a shape. Every point in the shape is moved in the same direction and by the same amount.

We have,

The triangle is translated 6 units up and 3 units left.

If vertex A is located at (-1, 2).

To Translate 6 units up we have to add 6 to the y coordinate.

and, to translate 3 units left we have to subtract 3 from the x coordinates.

So, the coordinates after translation is

A (-1,2)  -->  A' (-4,8)

B (1,5)  -->  B' (-2,11)

Answer:

the answer is A

Step-by-step explanation:

i went but the all the other answers in and it was left to  A

Option A is the correct answer.

What is the cost of one item if the cost of m items is x?

The cost of one item is obtained by dividing the total cost of m items by the number of items.

Given

The total amount spent by Sal > $24,

cost of 3 tennis balls = $2.

Cost of n tennis balls

Divide the cost of three tennis balls by 3 to get the cost of one tennis ball, which is $2/3.

Let the number of balls bought by Sal be n, and P be the cost of n tennis balls.

Total amount spent by him, P = cost of one ball × number of balls bought = ($2/3) × n = $(2/3)n.

Obtain the inequality

Since the total amount spent by him > $24, using the above value of P we obtain,

$(2/3)n > $24.

The inequality to be used to find n is (2/3)n > 24.

Answer:

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a rectangular prism in the form of a bathtub.

Given data

depth of bathtub= 24 in

width of bathtub= 24 in

length of bathtub= 60 in

the volume of water in the bathtub is a function of the depth of water in relation with the dimension of the bathtub.

the depth of water is 3 in below the the top

hence the depth of water (24 in- 3 in)= 21 in

the expression for the volume of water is given as

[tex]volume= length* width*depth\\volume= 60*24*21=30,240in^3[/tex]

Step-by-step explanation:

Both iscocoles and right angled triangles are very similar. They both measure differently and are not the same,

Answer:

point - slope form: y+1 =2(x+2)

slop - intercept form:  y =2x +3

standard form : 2x -y = -3 or -2x+y = 3

Step-by-step explanation:

find slope from given points using slope formula y₂ -y₁ / x₂ -x₁

slope m =5-(-1)/1-(-2) =6/3 =2

point - slope form is y - y₁ =m (x - x₁) where x₁ and y₁ are coordinates of one of the given points so

y - (-1) = 2(x -(-2))

y+1 =2(x+2)

slop - intercept form is y =mx +b where m is a slope and b is y intercept

now if you rearrange y+1 =2(x+2) as y =......

y+1 =2(x+2) → y+1=2x+4 → y = 2x+4-1 → y =2x +3

standard form is Ax +By = C where A,B,C are numbers; then by rearranging the equation again, it will be

2x -y = -3

graphing is done by using  slop - intercept form:  y =2x +3

The reason I'd decide to let these vehicles drive through the park is because, well, you never know if someone is in critical danger and needs urgent assistant. If the shortest route to get to the person is through the park, it'd be reasonable and understandable because you don't want that person do get hurt do you?

Answer:

Ishmail will  jog 7 1/2=7.5 miles if he completes 6 laps around the track if the track is pentagon.

Ishmail will  jog 9 miles if he completes 6 laps around the track, if the track is hexagon .

Step-by-step explanation:

length of one side of pentagon = 1/4 miles

we know that number of sides of pentagon = 5

thus, total length of pentagon = number of sides * length of one side of pentagon = 5* 1/4 = 5/4

If anyone takes 1 lap of pentagon he will travel 5/4 miles

then,If anyone takes 1*6 lap of pentagon he will travel (5/4)*6 miles

thus, in 6 laps 15/2 miles will be traveled.

Ishmail will  jog 15/2 ( 7 1/2 )miles if he completes 6 laps around the track.

_______________________________________

we know that number of sides of hexagon = 6

thus, total length of hexagon = number of sides * length of one side of hexagon = 6*( 1/4) = 3/2 miles

If anyone takes 1 lap of hexagon he will travel 3/2 miles

then,If anyone takes 1*6 lap of hexagon he will travel (3/2)*6 miles

thus, in 6 laps, 9 miles will be traveled.

Ishmail will  jog 9 miles if he completes 6 laps around the track.

Answer:

Sarah.

Step-by-step explanation:

Do not be fooled by how sharp the incline is, all of these graphs are labeled at different increments on both the x and y axes.

We will now solve this problem by figuring out each student's words per minute by dividing their words read (y-axis) by their time (x-axis).

Since the graphs are all linear, meaning they are constant and will never change. No matter what point we use on either graph we will come to the same words per minute for that student. For the sake of this explanation I will use the last point on each graph.

Charlie: Charlie read 1,750 words in 10 minutes, meaning he read at 175 words per minute. 1,750 / 10 = 175

Riley: Riley read 10,000 words in 50 minutes, meaning she read at 200 words per minute. 10,000 / 50 = 200

Sarah: Sarah read 1,300 words in 6 minutes, meaning she read at 216.67 words per minute. 1,300 / 6 = 216.67

Mason: Mason read 1,000 words in 5 minutes, meaning he read at 200 words per minute. 1,000 / 5 = 200

In conclusion, Sarah reads the fastest at 216.67 words per minute!

Therefore, the two ratios do form a proportion. Both are equivalent to [tex]\frac{1}{3}[/tex] when in simplest form.
