Can someone help me with this please?

Answer:

  f(x) = x³ -4x² -5x +20

Step-by-step explanation:

If the function is to have rational coefficients, each complex or irrational square root must have a matching conjugate. That is, both -√5 and +√5 must be roots. If there is a root p, then there is a factor (x -p). The factored form of the minimal polynomial is ...

  f(x) = (x -4)(x +√5)(x -√5)

  = (x -4)(x² -5)

  f(x) = x³ -4x² -5x +20

Answer:

y=4

Step-by-step explanation:

   y+2x=2

2(y+2x)=2(2)

 2y+4x=4

(2y+4x)-(y+4x)=4-0

                    y=4

Answer:

I think it's x=3 I think that's it

I think the answer is 3 because 4÷2=2. Hence, 6÷2=3

Answer:

Both of them are Non-Proportional since none are touching 0. I'm not sure if you're looking for Proportionality.

Answer:

B) y = 5x + 29

Step-by-step explanation:

A parallel line means it will have the same slope.

    So far our equation looks like this: y = 5x + b

We will now plug in (-6, -1) to solve for b.

    y = 5x + b

    (-1) = 5(-6) + b

    -1 = -30 + b

    29 = b

So our answer is y = 5x + 29

    This is option B

Have a nice day!

If I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

The term PEMDAS describes the sequence in which arithmetic operations must be carried out in an equation.

It is given that the length of the toy model car is 15 inches and the actual car is 20 feet

As we know 1 foot consists of 12 inches as a result  20 feet has 240 inches.

The scale distance between the toy model and the actual car is the difference between the actual length and the model length.

Scale distance = 240 inches - 15 inches

Scale distance =225 inches

Thus, if I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

Step-by-step explanation:

a midsegment is the line segment connecting the midpoints of two sides of a triangle. Since a triangle has three sides, each triangle has three midsegments (that create the midsegment triangle). A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side (due to similar triangles and their constant scaling factors, when one side of the similar triangle is half of the sys of the original triangle, then all its sides are half of their original counterparts).

the 3 sides of the main triangle are

2x + 5

3x - 1

5x

the perimeter of the main triangle is the sum of these :

2x + 5 + 3x - 1 + 5x = 10x + 4

since the sides of the midsegment triangle are all exactly half the length of the sides of the main triangle, also the perimeter of the midsegment triangle is half of the perimeter of the original triangle :

(10x + 4) / 2 = 5x + 2

To calculate each slope, just take any two points from each table, and plug them into this formula:⤵⤵⤵

(It'll be a bit small btw)

[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]

Table 1: I chose points (13,1) and (5,21)

21 - 1 = 20

5 - 13 = -8

Simplified = -5/2 ⬅ Slope

Table 2: I chose points (4,16) and (9,19)

19 - 16 = 3

9 - 4 = 5

3/5 ⬅ Slope

Table 3: I chose points (0,6) and (9,0)

0 - 6 = -6

9 - 0 = 9

Simplified = -2/3 ⬅ Slope

Table 4: I chose points (-8,1) and (-8,17)

17 - 1 = 16

-8 - (-8) = -8 + 8 = 0

Undefined slope (meaning the line will just be verticle)

Table 5: I chose points (2,3) and (3,5)

5 - 3 = 2

3 - 2 = 1

Simplified = 2 ⬅ Slope

Step-by-step explanation:

Since 20% down payment, we will find the 20% of that $250,000.

10% is $25,000, now times by 2 would be 20% which is $50,000.

Now $250,000 - $50,000 = $200,000 which would be rest of the non-payed payment.

We will divide $200,000 with the 25 year loan. $200,000/25 = $8,000

There is also the 5% interest.

1% of $8,000 is $80 and times that by 5 would be 5% which is $400.

$8,000 + $400 = $8,400.

Since it is monthly, we will divide $8,400 by 12 months. $8,400/12 = $700.

The monthly payment would be $700.
