Four is a zero of the equation x^3 + 3x^2 -18x - 40 = 0

Which factored form is equivalent to the equation?

Independent variable: The number of houses Harold sells

Dependent Variable: The amount of money Harold earns

Function: f(x)=250,000(x)

x represents how many houses Harold sells, and f represents how much money Harold earns.

Now, let's solve the problem.

f(x)=250,000(9)

f(x)=2,250,000

Harold earns $2,250,000

midpoint = ( [tex]\frac{13}{2}[/tex], - 6 )

using the midpoint formula

midpoint = [ [tex]\frac{1}{2}[/tex](4 + 9), [tex]\frac{1}{2}[/tex](- 10 - 2 )] = ( [tex]\frac{13}{2}[/tex], - 6)

nis after your done can you mind helping me after.. its ok if not.

Answer:

18

Step-by-step explanation:

Make a proportion 45/100  and x/45 then do cross multiplication then solve

Remark

They all have (0,0) as a point on the proportional relationship, so the general equation for this is

y = kx

Now all we have to do is find k

Method

If any two points (besides (0,0) ) give the same k as an answer then that is the proportional relationship.

Solution

(1/4) ÷(1/3)     Change to a decimal

0.25 ÷ 0.3333333 = 0.75

(4/4) ÷ (2/3) = 1 ÷ 0.666666 = 1.5 Rounded

A is not the answer

B

1 ÷ 2/7 = 1 ÷ 0.28571 = 3.5

2 ÷ 5/7 = 2÷ 7142857 = 2.8 Not the same

B is not the answer

C

(2/5) ÷  3 = 0.4 ÷ 3 = 0.13333333

(1/5) ÷ (3/2) = 0.2 / (1.5) = 0.13333333

Answer C

Comment

The answer is C or y = 0.133333 x

Notice that whenever possible, change these into decimals. Decminals are easier to handle.

Add them all up:

15 + 4 1/2 + 6 3/4 = 26 1/4 in.

2 ft equals 24 in.

2 1/2 ft = 30 in.

Yes, it is a valid claim.

Answer:

No. This is not a valid claim

Step-by-step explanation:

First we sum up the total snowfall for the 3 days as:

Monday= 15 inches

Tuesday=4.5 inches

Wednesday=6.75 inches

Total= 26.25 inches

As it is understood that there are 12 inches per foot. So we can simply multiply the number of inches it snowed during the last three days by this factor to find out.

26.25  in ×  1ft /12in ⇒

i.e. 26.25 x 1ft/12

which is 26.25ft / 12

that concludes 2.1875 ft

so it is not close to the forecaster said over 2 1/2 ft

on edge 2021 (:

Answer:

B

Step-by-step explanation:

The equation is (2x+5)^2.

It can't be A because 2 is the multiplier for only x.

It can't be C because the square is outside of the equation.

It can't be D because again, the square is outside of the equation.

So the only thing left is B.

Hope this helped!

How to get answer: First you need to use PEMDAS or GEMDAS

Another way of naming line m is AB

Last one is the answer

Answer: The fourth option. [tex]AB^{<-->}[/tex]

Step-by-step explanation:

BA stands for the segment between B and A, so this is not the correct option.

B (with a double arrow on top) refers to a line, but with only one point we could draw infinite lines, so this is not the correct option)

mB (with a double arrow on top) does not mean anything.

AB (with a double arrow on top) refers to a line that phases through the points A and B, so this is the other way of naming the line m.

First we find the slope of the given line as both the lines are parallel therefore their slopes are equal.

To find slope of given line we compare the equation with point slope form i.e.

[tex]y=mx+c[/tex]

On comparing [tex]y=2x+9[/tex]

We get [tex]m=9=slope [/tex]

As the required line is parallel to given line its slope is equal to given line

[tex]m=9[/tex]

Required line pass through[tex](3,1)[/tex]

Using point slope form

[tex]y-y_1=m(x-x_1)[/tex]

Here [tex]m=9, y_1=1, x_1=3[/tex]

Putting the values and solving

[tex]y-1=9(x-3)[/tex]

[tex]y-1=9x-27[/tex]

[tex]9x-y=26[/tex] is the required equation

Hope this will help

because of the shape it is molded as, some balloons are made to be hearts so when they are blown up they are shaped like hearts

For this case we have the following rule of three:

288 cars -------------------> 6days

Resolving you have that the value of the variable x is given by:

[tex]x =\frac{(1)(288)}{6}\\\\x = 48\\[/tex]

Thus, the constant of proportion per day is 48 cars.

Answer:

6 2/3 miles times 4 =

Step-by-step explanation:

Convert the fraction 2/3 to a decimal

2/3  = .67

6.67 miles times 4 = 26.68 miles

or 6x4= 24

2/3+2/3+2/3+2/3  =8/3 or 2 2/3

2 2/3 +24 =26 2/3 miles

Last week I jogged for [tex]26\frac{2}{3}[/tex] miles in 4 times.

An improper fraction is when the value in the numerator is more than the value in the denominator.We can also write improper fraction in the form where we write the whole part and with a proper fraction where numerator is the remainder and denominator remains the same.

According to the given question

I jog [tex]6\frac{2}{3}[/tex] miles around a track last week I jogged 4 times around that track

therefore my total jogging distance will be

= 4([tex]6\frac{2}{3}[/tex]) miles

= 4 × 20/3 miles

= 80/3 miles

= [tex]26\frac{2}{3}[/tex] miles

(30-49)/(42/6)6*8=184

Step-by-step explanation:

-11 is the smallest integer!

Why? Because it's a negative number. -5 is the closest to being a positive. 15 is the largest integer so the answer is -11

3 x 4 = 12 because there are 4 sides and the length is 3, you multiply 3 and 4 together.

Answer:

Perimeter of square=12x

Step-by-step explanation:

the perimeter of a square with sides of length 3x

The side length of the square is 3x

To find perimeter we add all the sides. All sides are same in a square.

Perimeter of square= 4(a)

where 'a' is the side length

a= 3x. Substitute 3x for 'a'

Perimeter of square= 4(3x)=12x

9 * 9 * 9 = 729. This is also an exponent 9^3.

When you determine the powers you need to multiply the number itself how many times the power says to multiply.

9 raised to the power of 3 is equal to 729.

Given that we need to find that what is 9 to the power of 3.

To calculate 9 to the power of 3, we need to multiply 9 by itself three times.

In mathematical notation, it is written as 9³.

First, we start with 9 and multiply it by itself:

9 × 9 = 81

Next, we multiply the result by 9 again:

81 × 9 = 729

In simpler terms, it means that if you multiply 9 by itself three times, you get the result of 729.

Therefore, 9 raised to the power of 3 is equal to 729.

Final answer:

The daughter is 10 years old, and the mother is 36 years old. We solved two equations simultaneously to find their ages, based on the relationship between their ages and their combined total age.

Explanation:

To solve the problem, we need to set up two equations based on the information provided. Let's denote the daughter's age as d and the mother's age as m. We are given that the mother is 6 years older than 3 times her daughter's age. Formally, this can be expressed as:

m = 3d + 6

Next, we know that their combined ages total 46. This leads to a second equation:

m + d = 46

We can use these two equations to solve for d and m. Substituting the expression for m from the first equation into the second gives:

3d + 6 + d = 46

We simplify this to find d:

4d + 6 = 46

4d = 40

d = 10

Now we can use this to find m:

m = 3(10) + 6

m = 30 + 6

m = 36

So the daughter is 10 years old and the mother is 36 years old.

im gonna say always a monomial ...

Answer: Always

Step-by-step explanation:

Well, there really isn't an equation for this. Just plug in numbers and see if the numbers have to be bigger or smaller than the one you guessed. In this case, after plugging in a couple of numbers, I plugged in 17 for the smaller number. Then to find the bigger number, I multiplied 17 by 3, which is 51, then subtracted 7 from 51, which is 44. Since 44+17=61, the numbers are 44 and 17.
