Answer:

8x^3+2x^2-3x+4

Step-by-step explanation:

8x³ +2x² -3x+4 is the standard form of the  (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

An expression is combination of variables, numbers and operators.

The given expression is  (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

7x³ + 7x² – 4+x³ – 5x² – 3x + 8

In the given expression x is the variable

Plus and minus signs are the operators of the given expression.

Add the like terms in the given expression

8x³ +2x² -3x+4

Hence, 8x³ +2x² -3x+4 is the standard form of the  (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = [tex]\frac{1}{5}x + 2[/tex]

Find two points

When x = 0 ,  y = 0 + 2 = 2

D(0 , 2)

When x = 5;

    [tex]y=\frac{1}{5}*5+2= 1 + 2 = 3[/tex]

E(5, 3)

Plot (0, 2 ) and (5 , 3) in the graph and join the points. This will be the line for the equation y =(1/5)x + 2

y = -x + 8

When x =4 ,  y = -4 + 8 = 4

A(4 , 4)

When x = 6 ;   y = -6 + 8 = 2

B(6 , 2)

Plot (4,4) and (6, 2) in the graph and join the points. This will be the line for the equation y = - x + 8.

This lines will intersect at  point (5,3) and  that point will be the solution of the equation.

Step-by-step explanation:

The sides that correspond to each angle in triangle ABC are:

Angle XYZ corresponds with side length YZ

Angle ZXY corresponds with side length XZ

Angle YZX corresponds with side length YX

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Since, We know that;

The corresponding sides are segments located at the same relative position of an angle.

So, the corresponding sides of the angles are:

Side YZ & angle XYZ,

Side XZ & angle ZXY,

And, Side YX and angle YZX

Thus, The sides that correspond to each angle in triangle ABC are:

Angle XYZ corresponds with side length YZ

Angle ZXY corresponds with side length XZ

Angle YZX corresponds with side length YX

Answer:

Quadratic function, None of the above, and ?

Step-by-step explanation:

So remember what I told you about earlier, lets look at that first one.

So we can see that x is increasing by 1 and y is decreasing by 3...And then it increases by 3! And after that another 9! Well, that seems like it is reversing, as it changes from decreasing to increasing in y coordinates. So knowing that is reverses from decreasing to increasing in y, it must be a quadratic function!

Next we have a increase in 1 and a decrease by 17...then 12...then 7 in y. This isnt decreasing by a constant amount like a linear function. It doesnt seem like a obvious exponential decrease either, and it isnt reversing like a quadratic function does. I am going to use something called logarthms, which you don't even need to think about yet, just to make sure that it is not an exponent.  Althouhg the difference in the exponent was only 0.0018, it is a differnece. So this must be a none of the above, sicne none of the functions apply. (If this is incorrect, and it is exponential, then the test is wrong. While the method I used is something found in mid algebra 2, it is still a method of finding a exponent of a number.)

Now we finish up with a change in x of 1, and a change of y by...-11, -11, -11!

Well, what do you think this is, thinking back on what I have said so far.

It is a constant change of -11y and 1x. Remember, a CONSTANT CHANGE.

What do you think it is :)

If you cannot figure it out, let me know in comments.

Answer:

A dot plot generally shows the data for a specific value, it is just like how you would need each individual's score. A histogram shows data for a range of values. The best one to use here is a histogram.

Step-by-step explanation:

Answer:   The answer is C

Step-by-step explanation:   Histograms show ranges and the table shows ranges and scores.  A dot plot would not fi this situation as well as histograms because histograms are best when it comes to ranges.

Answer:

7cm=7×3ft=21ft

4cm=4×3ft=12ft

here

length=21ft

breadth=12ft

now

area= l×b

=21ft×12ft

=252ft^2

Answer: 252 ft²

Step-by-step explanation:

The drawing's dimensions are given to be 7 cm in length, and 4 cm in width. Those values are multiplied by 3 to get the scaled drawing. This gives us 21 feet and 12 feet. When you multiply 21 feet by 12 feet, you get 252 ft². DO NOT FORGET to put the ² in the final answer.

Answer:

5.5 is the median

Step-by-step explanation:

Answer:

y = x + 2.5

Step-by-step explanation:

slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points

slope = (2.5-1.5)/(0+1) = 1

equation = y-y1 = m(x-x1)

y - 2.5 = x

y = x + 2.5

Answer: B. 65

Step-by-step explanation:

Choose any point on the number line with natural numbers for both coordinates. For this case, let's use (4, 260).

To find the constant of proportionality, divide the Y coordinate by the X coordinate. 260 ÷ 4 = 65. While optional, it is reccomended to use two points to confirm your answer. Let's do that with (2, 130). Since 130 ÷ 2 = 65, this confirms that the constant of proportionality is 65.
