<h2>Answer:</h2>

The mathematical expression 2 ∈ V means that:

        2 is an element of set V.

<h2>Step-by-step explanation:</h2>

We know that for any set A with elements as:

            A={a,b,c,d}

We see that that the element a,b,c and d all belongs to the set A and is represented by the symbol:

          a ∈ A, b ∈ A , c ∈ A and d ∈ A

i.e. they represent that the element is contained in that set.

Here we  2 ∈ V

This means for a set V of elements.

The element 2 belongs to the set.

i.e. it is a member of the set.

Use DESMOS: What is the equation
Masja [62]

y=mx+c

I picked the points (0, -4) and (-2,-10) to find the gradient of the line

M= rise/run

= 6/2

=3

Y-intercept is at - 4

Y= 3x - 4 is equation of the line given

Reciprocal of 3 is 1/3

(m1 x m2 = - 1)

So, to make - 1, our second gradient should be negative.

Gradient of the perpendicular line will be - 1/3

Y= - 1/3x + c

Substitute value of x & y into the equation

(-6,6) means x = - 6, y = 6

y = - 1/3x +c

6 = - 1/3 x - 6 + c

6 = 2 + c

-2

4 = c

Thus, final equation we're after will be:

y= - 1/3x + 4

Hope this helps!

If 8 cakes cost $62.40, how much would 3 cakes cost?
Ilya [14]

Answer:

<h2><em><u>$23.40 </u></em></h2>

Step-by-step explanation:

<em><u>Given,</u></em>

Cost price of 8 cakes = $62.40

<em><u>So,</u></em>

Cost price of 1 cake = $ \frac{62.40}{8}

<em><u>Therefore,</u></em>

Cost price of 3 cakes

= $(\frac{62.40}{8} × 3)

  • <em>[On dividing 62.40 by 8]</em>

= $(7.80 × 3)

  • <em>[On multiplying]</em>

= $23.40

<em><u>Hence,</u></em>

<em><u>The required cost of 3 cakes is $23.40 (Ans)</u></em>
