Answer:

Step-by-step explanation:

You have the domain. It is given as -1≤x≤1

Now all you have to do is figure out the range which is the y value. At first glance I think it might be 3, but that does not look very logical. I'll post this much of it now and be back in under an hour with a more complete answer.

Of course! How silly of me. There is a minimum of y = 1 in the range which comes from x = 0

I've included a graph so you can see how this all works.

So the range = 1 ≤ y ≤ 3

2. The ratio of

denpristay [2]

Answer:

Step-by-step explanation:

Given the ratio of the profit, cost of materials and labour in the production of

an article to be 5:7:13 respectively, total ratio = 5+7+13 = 25

If the cost of labour is x, the cost of material will be 840+x (since the cost of materials is Le 840 more than that of labour) .

Let the total cost of producing the article be y.

Cost of labour = 13/25 * y = x

Cost of labour = 13y/25 = x.................... 1

Cost of material = 7/25*y = 840+x

Cost of material = 7y/25 = 840+x ..................... 2

From 1, 13y = 25x

x = 13y/25 ................... 3

Substituting equation 3 into 2:

7y/25 = 840+x

7y/25 = 840+13y/25

collect the like terms:

7y/25 - 13y/25 = 840

-6y/25 = 840

-6y = 25*840

y = 25*840/6

y = 3,500

<em>Hence the total cost of producing the article is 3500</em>

What is 2/3x=2y+6 in ax+by=c form?

kifflom [539]

Answer:

2x - 6y = 18

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

$\frac{2}{3}$ x = 2y + 6

Multiply through by 3 to clear the fraction

2x = 6y + 18 ( subtract 6y from both sides )

2x - 6y = 18 ← in standard form

What is the midpoint of the line segment that has endpoints (3,8) and (1,−4) ?

bezimeni [28]

Answer:

Step-by-step explanation:

<em>Midpoint Formula:</em>

$\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}$

$\frac{3+1}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$\frac{8+-4}{2}$ ⇒ $\frac{8-4}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$(2,2)$
