help please, the question in the picture

Answer:

Step-by-step explanation:

1) first we find the x and y intercepts. Remember the intercepts are where x=0 and y=0

2) To find the x-intercept, substitute y = 0 and solve for x.

given equation:  x +2y= -4

then substitute y=0    so

x+ 2(0) = -4    -> any number multiplied by 0 it will always equal zero

then,  it will be  x=-4

the coordinates will be (-4,0)

3) To find the y-intercept, substitute x =0 and solve for y.

given equation:  x +2y= -4

then substitute x=0    so

(0)+ 2y = -4    -> x disappears since is zero

then,  it will be  2y=-4

then we multiply by 2 :

2y/2 = -4/2

y=-2

the coordinates for the y-intercept will be (0,-2)

Step-by-step explanation:

In general equation, y = mx+c, c represents y-intercept.

So, y-4 = 6x+42

y = 6x+46

So, y intercept will be 46

Explanation:

Let's list out all the ways to multiply to 72 using two values

1*72

2*36

3*24

4*18

6*12

8*9

Then cross off something like 2*36 since 2 is prime. We also cross off 3*24 since 3 is prime.

We're left with this list

1*72

4*18

6*12

8*9

which represent the possible dimensions of this rectangle.

Keep in mind that 1 is not prime.

                  The volume of cone will be [tex]\frac{88r^{3} }{21}[/tex]

Cone:

        A cone is a three-dimensional geometric shape that tapers smoothly from a flat base.

Given,

        The height of a cone is two times its base diameter.

         we have to find the volume of cone in terms of base radius.

let us assume the base radius of cone is equal to r units

                    so diameter(d) of cone will be, d= 2r units

so,

     height(h) of cone will be equal to, h = 2d units

                                                           h = 2x2r units

                                                           h = 4r  units

We know,

              Volume of the cone(V) = [tex]\pi r^{2} h/3[/tex]

                Where,

                             r = radius of base

                            h = height of cone

                            π = 22/7

Thus by using formula,

                                   Volume of cone(V) = [tex]\pi r^{2} h/3[/tex]

                                                                 = 22/7 * [tex]r^{2}[/tex] * 4r/3

                                                                 = 88[tex]r^{3}[/tex]/21

                                                                 = [tex]\frac{88r^{3} }{21}[/tex]

  Hence,

              The volume of cone will be [tex]\frac{88r^{3} }{21}[/tex]

Part a

The equation for the way Michelle is paid is

Total weekly payment y = 495.50 + 0.105x

Part b

The total payment in a  month = $4021.625

She makes a 10.5% commission on every kayak she sells

Consider the total value of kayaks she sold = x

The rate of commission = 10.5%

The amount of commission = x × (10.5/100)

= 0.105x

The weekly fixed payment = $495.50

Total weekly payment y = 495.50 + 0.105x

Part b

The total value of the kayaks she sold = $19425

Total number of weeks in a month = 4

Then the total payment in a month = (4 × 495.50) + (0.105×19425)

= 1982 + 2039.625

Cost for each pound of chocolate chips is equal to $3.5.

Cost for each pound of walnuts is equal to $1.75

In order to solve this word problem, we would assign variables to the cost for each pound of chocolate chips and each pound of walnuts respectively, and then translate the word problem into algebraic equation as follows:

For 3 pounds of chocolate chips and 2 pounds of walnuts, we have:

3c + 2w = 14              .....equation 1.

For 5 pounds of chocolate chips and 6 pounds of walnuts, we have:

5c + 6w = 28      .....equation 2.

Solving the system of equations by using the elimination method, we have:

3 × (3c + 2w = 14) = 9c + 6w = 42

                                5c + 6w = 28_

4c = 14

c = 14/4

c = $3.5

For the cost for each pound of walnuts, we have:

3c + 2w = 14

3(3.5) + 2w = 14

10.5 + 2w = 14

2w = 14 - 10.5

By the principle of mathematical induction, it has been proved that

[tex]p^3 + 11p[/tex] is divisible by 6

What is Principle of mathematical induction?

Let the statement be given by P(n). At first P(n) is proved to be true for 1. Then it is assumed that P(n) is true for all n. If P(n) is true for (n+1) then by Principle of Mathematical induction, P(n) is true for all natural numbers

The given expression is [tex]p^3 + 11p[/tex]

For p = 1

[tex](1)^3 + 11 \times 1\\12[/tex]

which is a multiple of 6

Let it be true for p = m

[tex]m^3 + 11m[/tex] is a multiple of 6

[tex]m^3 + 11m = 6k[/tex], where k is any integer

For p = m + 1

[tex](m+1)^3 + 11(m+1) \\m^3+3m^2+ 3m +1+11m+11\\m^3+11m +3m^2+3m+12\\m^3+11m + 3m(m+1) + 12[/tex]

Now,

[tex]m^3 + 11m[/tex] is divisible by 6

We know that the product of two consecutive integers are divisible by 6

[tex]3m(m+1)[/tex] is divisible by 6

12 is divisible by 6

[tex](m+1)^3 + 11(m+1)[/tex] is divisible by 6

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, 2 market women shared 300 oranges.

The share of first woman is twice the other.

Let the number of oranges with other women be x.

Then, the number of oranges with first women will be 2x.

Now, x+2x=300

The probability of an event in an experiment is obtained as the number of desired outcomes in the context of the experiment divided by the number of total outcomes in the context of the experiment.

The total number of notes in this problem is composed as follows:

Hence the total number is of:

Total = 7 x 4 + 8 x 3 = 52 notes.

The desired number of outcomes is the number of notes with C, hence:

Desired = 8 notes.

Thus the probability is calculated as follows:
