Answer:

x + y - 1 = 0

Step-by-step explanation:

y = -x - 11

therefore its slope is -1

x1= -3

y1 = 4

m = -1

from, y - y1 = m(x -x1)

y - 4 = -1(x + 3)

y -4 = -x -3

x + y -1 = 0

Answer:

Luca needs to throw the ball 10 meters to get to Valentina.

Step-by-step explanation:

Distance Between two Points in the Plane

Let's assume Luca is at the origin of coordinates (0,0).

Since Herman is 6 meters south of Luca, he is located at (0,-8).

We also know Herman is 8 meters west of Valentina, or equivalently, Valentina is 8 meters east of Herman. This locates Valentina at (6,-8).

If Luca wanted to throw the ball to Valentina, he would need to cover the distance between them.

Thus the problem reduces to find the distance between (0,0) and (6,-8).

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

Applying the formula:

[tex]d=\sqrt{(-8-0)^2+(6-0)^2}[/tex]

[tex]d=\sqrt{(-8)^2+(6)^2}[/tex]

[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]

d=10 m

Luca needs to throw the ball 10 meters to get to Valentina.

Answer:

60 boys are in the grade.

Step-by-step explanation: Since there are 150 students, we can divide that number by the combined ratio, which in this case is 5. Dividing 150 by 5 would yield 30 students. We can use this information to multiply the given number of boys in the ratio by 30, which would produce 60.

Answer:

£20

Step-by-step explanation:

Given that:

Total amount alloted = 2000

Ticket cost = 32

Discount = 1/4 off

Hence, ticket price = 3/4 * 32 = 24

Train ticket cost = 12

Total cost per person = £(12 + 24) = £36

Hence, alloted amount / cost per person

= £2000 / £36

= 55.55

Total number that can attend = 2 teachers and 53 students

Change = £2000 - (£36*55)

= £20

Answer:

y= -2 +490

3

Step-by-step explanation:

y=mx+b is the slope intercept form of a like where m is the slope and b is the y intercept

Answer:

y=-2/3x+490

Step-by-step explanation:

As we know the formula for slope intercept form would be y=mx+b

therefore we arrange our numbers in the following manner:

First subtract 2x from 2x so it'll be like 2x-2x and they cancel each other out so keep that in mind, now what you do on one side you have to do it on the other side as well therefore you'll putt -2x on the other side now we are left our equation as 3y=1,470-2x

Second, as we want our form to be slope intercept form I believe that y should be by it self and to do that you need to divide 3 from y, now remember that what you do on one side you have to do it on the other. So you'll divide 3 from all the numbers on the other side. Now on the other side we have 1,470-2x so we will divide 1,470/3=490 and -2x/3 now we are left with y= 490-2/3x ( i left -2/3x as that because dividing makes it a decimal and a decimal and the fraction has the same value so I just left it as a fraction)

Thirdly, sense we want our equation as a slope intercept form we will need to rearange our equation which we need to keep in mind the form which is y=mx+b so that makes it to our answer y=-2/3x+490

Hope this helps :)

Answer:

d

Step-by-step explanation:

I am pretty sure that is the answer

A function assigns the values. The value of (f +g)(x) for the two given functions f(x)=5x³+2x²–7x+4 and g(x)=3x–7 is 5x³ + 2x² – 4x – 3. The correct option is D.

A function assigns the value of each element of one set to the other specific element of another set.

Given the two functions such as,

f(x) = 5x³ + 2x² – 7x + 4

g(x) = 3x – 7

Now, the value of (f +g)(x) is the value of the function which is produced when the two of the given function are added together, therefore, the value of the added function can be written as,

(f +g)(x) = f(x) + g(x)

(f +g)(x) = (5x³ + 2x² – 7x + 4) + (3x – 7)

            = 5x³ + 2x² – 7x + 4 + 3x – 7

             = 5x³ + 2x² – 4x – 3

Hence, the value of (f +g)(x) for the two given functions f(x)=5x³+2x²–7x+4 and g(x)=3x–7 is 5x³ + 2x² – 4x – 3.

Answer:

A

Step-by-step explanation:

The signs do not follow the right pattern.

The first and last terms are not perfect cubes explains why the polynomial cannot be factored using the binomial theorem

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

The given polynomial is:

125x³ + 900x² – 2,160x + 1,728

To factor this polynomial using the binomial theorem, we would need to write it in the form (a + b)³

where a and b are expressions in x.
However, the given polynomial does not seem to fit this form, since the coefficients and exponents of the terms do not follow the pattern of the binomial expansion.

The first and last terms, 125x^3 and 1,728, are perfect cubes, but they do not have a common factor that can be factored out.

Therefore, we cannot write them in the form (a + b)³.

So, the correct answer is the first and last terms are not perfect cubes.

Answer:

Kay sold 6 boxes and Ayan sold 19 boxes

Step-by-step explanation:

Let x = number of boxes Kay sells

y = number of boxes Ayan sells

Then the equations will be:

[tex]x+y = 25\\x = y-13[/tex]

We can solve the system by using substitution method

Putting x = y-13 in equation 1

[tex]y-13+y = 25\\2y -13 = 25\\2y = 25+13\\2y = 38[/tex]

Dividing both sides by 2

[tex]\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]

Putting y = 19 in equation 2

[tex]x = y-13\\x = 19-13\\x = 6[/tex]

Hence,

Kay sold 6 boxes and Ayan sold 19 boxes

Answer:

Answer:

11 ; 12°

Step-by-step explanation:

3x + 28 + 2x - 10 + 5x + 52 = 180

10x = 180 - 70

x = 11

m∠C = 2(11) - 10 = 12°

Answer:

Angle ACB = 12°

Step-by-step explanation:

All angles in a triangle always add up to 180°, which gives us an equation to solve for x:

3x + 28 + 5x + 52 + 2x -10 = 180

Combine like terms

10x + 70 = 180

Subtract 70 from both sides

10x = 110

Divide both sides by 10

x = 11

Now we know the value of x, we need to just plug it in to angle ACB's given value:

2(11) - 10 = Angle ACB

22 - 10 = Angle ACB

12 = Angle ACB

Step-by-step explanation:

1. Jun needs to review for the entrance exam with his remaining 5 3/5 hours fo the 7 subjects. how long will he spend for each subject?

The time spent on each subject will be the remaining hours left divided by 7. This will be:

= 5 3/5 ÷ 7

= 28/5 ÷ 7

= 28/5 × 1/7

= 28/35 = 4/5 hours

Since 60 minutes make one hour

4/5 hours = 4/5 × 60 = 48 minutes

2.Mar purchased 6 3/4 meters of wall paper for the boxes he will cover. if each box needs 2 1/4 meters, how many boxes will get covered?

This will be:

= 6 3/4 ÷ 2 1/4

= 27/4 ÷ 9/4

= 27/4 × 4/9

= 3 boxes

3.Joana has 12 1/4 meters of ribbon, joy has 3meters ribbon shorter than joana. they split the ribbon to have the an equal length of ribbon. how long is each.

Joana ribbon = 12 1/4 meters

Joy's ribbon = 12 1/4 - 3 = 9 1/4 meters

We then add both length of ribbons and divide by 2. This will be:

= 12 1/4 + 9 1/4

= 21 1/2 meters

= 21 1/2 meters ÷ 2

= 43/2 ÷ 2

= 43/2 × 1/2

= 43/4

= 10 3/4 meters
