How do I find the coordinates of the point P that lies along the directed segment from C(-3,-2) to D(6,1) and partitions the segment in the ratio 2 to 1?

Answer:

c

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and

b is the y-intercept.

y=mx+b

m=−3

b=0

y=-3x+0

The required y-intercept of the given y = -3 is (0, 0)

Slope-intercept form of the line:

If the line have m slope and b as y-intercept then the equation of the line will be y = mx + b

Here we have given that the equation of the line

y = -3x

Make this equation like general form of slope-intercept form

y = -3x + 0

Therefore comparing with general form we have

Slope m = -3

y-intercept = b = 0

The coordinate will be (0, 0)

Therefore the correct option is (c)

This is the conclusion to the answer.

Answer: choice D

2x^5 - 6x^3 + 3x^2 - x

Explanation:

Polynomials in standard form always have the exponents decrease (ie go from largest to smallest) when we read from left to right. For choice D, the exponents from left to right are: 5, 3, 2, 1. This is decreasing order. The other answer choices do not have the exponents in decreasing order. The degree of the polynomial in choice D is a 5th degree polynomial since 5 is the largest exponent.

Answer: Yes

Step-by-step explanation: Erica would be correct. 4x is called a term. When we see a variable next to a number which in this case is X, it's important to understand that this means multiplication.

We can also say that the expression 4x is a product of both 4 and X.

Final answer:

Erica is correct; the expression 4x is considered one term because it consists of a single element with a coefficient and a variable multiplied together.

Explanation:

Erica is correct in saying that the expression 4x has one term. In mathematics, a term is a single mathematical expression that may be a number, a variable, or numbers and variables multiplied together. The expression 4x consists of the number 4 and the variable x multiplied together, which forms a single term. It does not have any addition or subtraction signs that would separate it into multiple terms.

Answer:

y = 4x + 20

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 5, 0) into the partial equation

0 = - 20 + c ⇒ c = 0 + 20 = 20

y = 4x + 20 ← equation of line

Answer:

900 minutes

Step-by-step explanation:

Plan A: 700 free minutes + 15 cents per minute over 700 ($40)

Plan B: 500 free minutes + 5 cents per minute over 500 ($50)

The charges for x minutes (assumed x>700) for plan A will be

40+0.15(x-700)

The charges for x minutes (assumed x>500) for plan B will be

50+0.05(x-500)

To find the value of x where both charges are the same, we equate

40+0.15(x-700)=50+0.05(x-500)

Operating

40+0.15x-105=50+0.05x-25

Simplifying

0.10x=90

x=900 minutes

Both plans would charge the same amount when 900 minutes per month are used

Answer:

Co-ordinates of point R is (26,2)

Step-by-step explanation:

Given point:

Endpoint S(8,4)

Mid-point M of segment RS (17,3)

Let endpoint [tex]R[/tex] have co-ordinates [tex](x_2,y_2)[/tex]

Using midpoint formula:

[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are co-ordinates of the endpoint of the segment.

Plugging in values to find the midpoint of segment KN.

[tex]M=(\frac{8+x_2}{2},\frac{4+y_2}{2})[/tex]

We know [tex]M(17,3)[/tex]

So, we have

[tex](17,3)=(\frac{8+x_2}{2},\frac{4+y_2}{2})[/tex]

Solving for [tex]x_2[/tex]  

[tex]\frac{8+x_2}{2}=17[/tex]

Multiplying both sides by 2.

[tex]\frac{8+x_2}{2}\times 2=17\times 2[/tex]

[tex]8+x_2=34[/tex]

Subtracting both sides by 8.

[tex]8+x_2-8=34-8[/tex]

∴ [tex]x_2=26[/tex]

Solving for [tex]y_2[/tex]  

[tex]\frac{4+y_2}{2}=3[/tex]

Multiplying both sides by 2.

[tex]\frac{4+y_2}{2}\times 2=3\times 2[/tex]

[tex]4+y_2=6[/tex]

Subtracting both sides by 4.

[tex]4+y_2-4=6-4[/tex]

∴ [tex]y_2=2[/tex]

Thus co-ordinates of point R is (26,2)  (Answer)

To fit two identical cars in a 23-foot 6-inch wide garage with 3 feet 6 inches clearance on each side and between the cars, the cars must each be 6 feet 6 inches wide.

The subject matter of your question is a math problem involving subtraction and division. To find out how wide the cars can be, you first need to determine the total available space for the cars. The total width of the garage is 23 feet 6 inches. However, you need to leave room for clearance on either side of the cars and in between them. The clearance is a total of 3 feet 6 inches multiplied by 3 (one for each side and one for between the cars), which is 10 feet 6 inches. Subtract this from the total width of the garage, and you get 13 feet available for the cars. Since the cars are identical, you simply divide this by 2. Each car can be 6 feet 6 inches wide.

Answer:

Total number of Jelly beans in the sack = 72

Number of red beans = 36

Number of green beans = 12

Number of yellow beans = 12

Number of orange beans = 6

Number of black beans = 6

Step-by-step explanation:

Let total number of jelly beans be =[tex]x[/tex]

We are given fractions of different colors of beans. To find the exact number of beans we need to multiply the fraction with the total number of beans.

Fraction of total are red beans = [tex]\frac{1}{2}[/tex]

Number of red beans = [tex]\frac{1}{2}\times x= \frac{x}{2}[/tex]

Fraction of total are green beans = [tex]\frac{1}{6}[/tex]

Number of green beans = [tex]\frac{1}{6}\times x= \frac{x}{6}[/tex]

Fraction of total are yellow beans = [tex]\frac{1}{6}[/tex]

Number of yellow beans = [tex]\frac{1}{6}\times x= \frac{x}{6}[/tex]

Fraction of total are orange beans = [tex]\frac{1}{12}[/tex]

Number of orange beans = [tex]\frac{1}{12}\times x= \frac{x}{12}[/tex]

Number of black beans = 6

Total number of beans can be given as

[tex] \frac{x}{2}+\frac{x}{6}+\frac{x}{6}+\frac{x}{12}+6[/tex]

Since we assumed total number of beans to be [tex]x[/tex], so we have.

[tex] \frac{x}{2}+\frac{x}{6}+\frac{x}{6}+\frac{x}{12}+6=x[/tex]

Multiplying each term by 12 to remove fractions.

[tex] (12\times\frac{x}{2})+(12\times\frac{x}{6})+(12\times\frac{x}{6})+(12\times\frac{x}{12})+(12\times6)=12\times x[/tex]

[tex]6x+2x+2x+x+72=12x[/tex]

combining like terms.

[tex]11x+72=12x[/tex]

Subtracting both sides by [tex]11x[/tex]

[tex]11x+72-11x=12x=11x[/tex]

[tex]72=x[/tex]

∴ [tex]x=72[/tex]

Total number of Jelly beans in the sack = 72

Number of red beans = [tex]\frac{1}{2}\times 72= 36[/tex]

Number of green beans = [tex]\frac{1}{6}\times 72= 12[/tex]

Number of yellow beans = [tex]\frac{1}{6}\times 72= 12[/tex]

Number of orange beans = [tex]\frac{1}{12}\times 72= 6[/tex]

number of black beans = 6

Justin has 72 jelly beans in total. By dividing the total number accordingly, he has 36 red, 12 green, 12 yellow, 6 orange, and 6 black jelly beans.

Let's assume the total number of jelly beans Justin has is represented by the variable x. We know that half of them are red, so there are x/2 red jelly beans. Similarly, since 1/6 are green and another 1/6 are yellow, there are x/6 green jelly beans and x/6 yellow jelly beans. As for the orange jelly beans, they represent 1/12 of the total, which means Justin has x/12 orange jelly beans. We are given that there are 6 black jelly beans, which do not need to be divided into fractions. To find the total, x, we can write an equation considering all the portions mentioned and the known number of black jelly beans:

x/2 (red) + x/6 (green) + x/6 (yellow) + x/12 (orange) + 6 (black) = x

Finding a common denominator (12), we rewrite the equation:

6x/12 + 2x/12 + 2x/12 + x/12 + 6 = x

Combine like terms:

(6x + 2x + 2x + x)/12 + 6 = x

11x/12 + 6 = x

To solve for x, subtract 11x/12 from both sides:

6 = x - 11x/12

6 = x(12/12) - 11x/12

6 = (12x - 11x)/12

6 = x/12

Multiplying both sides by 12 gives us:

x = 72

So, Justin has a total of 72 jelly beans. Calculating the number for each color:

In conclusion, Justin has 36 red, 12 green, 12 yellow, 6 orange, and 6 black jelly beans, adding up to a total of 72 jelly beans.

Step-by-step explanation:

Let,

Quarters = x

Dimes = y

Pennies = z

We know that,

A quarter is 25 cents, dime is 10 cents and penny is 1 cent.

Total amount = $6.60 = 6.60*100 = 660 cents

According to given statement;

25x+10y+z=660   Eqn 1

x=2z    Eqn 2

y=z+5   Eqn 3

Putting these values of x and y in Eqn 1

[tex]25(2z)+10(z+5)+z=660\\50z+10z+50+z=660\\61z=660-50\\61z=610\\[/tex]

Dividing both sides by 61;

[tex]\frac{61z}{61}=\frac{610}{61}\\z=10[/tex]

Putting z=10 in Eqn 2

[tex]x=2(10)\\x=20[/tex]

Putting z=10 in Eqn 3

[tex]y=10+5\\y=15[/tex]

He has 20 quarters, 15 dimes and 10 pennies.

Answer:

$60

Step-by-step explanation:

Let the company's fixed charge be "x"

And let the the hourly rate be "h"

Firstly, 2 hours + fixed = $110, we can write:

2h + x = 110

Next, 3 hours + fixed = $150, we can write:

3h + x = 150

We multiply the first equation by "-1" to get:

-1 * [2h + x = 110] = -2h - x = -110

Now we add this equation to the 2nd:

3h + x = 150

-2h - x = -110

-------------------

h = 40

Hence, the hourly rate is $40

So, it would cost 1.5 * 40 = $60 for 1.5 hours
