Answer:

y=2x

Step-by-step explanation:

Hey!

This is a direct variation problem:

Direct variation describes a simple relationship between two variables . We say y varies directly with x.

y=kx, where k is the constant of variation or constant of proportionality.

==================================================================

We can substitute x and y in the given equation.

40=k20

Divide by 20 on both sides.

40/20=k

k=2

Substitute k in the Direct variation Equation:

y = 2x

==================================================================

Hope I helped, feel free to ask any questions to clarify :)

Have a great day!

Instructions:select all the correct locations on the tables. andrew wants to purchase a new television with a screen length that

DaniilM [7]

The correct answers are:

5x²+70x+245 ≥ 1050; and

Yes.

Explanation:

Let x be the width of the tablet. Since the width of the TV is 7 inches more than the tablet, the width of the TV would be x+7.

The length of the TV is 5 times the width; this makes the length 5(x+7) = 5x+35.

The area of the TV would be given by

(x+7)(5x+35).

Since Andrew wants the area to be at least 1050, we set the expression greater than or equal to 1050:

(x+7)(5x+35) ≥ 1050

Multiplying this, we have:

x*5x+x*35+7*5x+7*35 ≥ 1050

5x²+35x+35x+245 ≥ 1050

Combining like terms,

5x²+70x+245 ≥ 1050

To see if 8 is a reasonable width for the tablet, we substitute 8 for x:

5(8²)+70(8)+245 ≥ 1050

5(64)+560+245 ≥ 1050

320+560+245 ≥ 1050

1125 ≥ 1050

Since this inequality is true, 8 is a reasonable width.

Answer:

$Center = \boxed{1}, \: \boxed{ - 2} \: ; \: Radius = \boxed{3}$

Step-by-step explanation:

${x}^{2} + {y}^{2} - 2x + 4y - 4 = 0 \\ \\ ({x}^{2} - 2x + 1 - 1) + ( {y}^{2} + 4y + 4 - 4) - 4 = 0 \\ \\ ( {x}^{2} - 2x + 1) + ( {y}^{2} + 4y + 4) - 9 = 0 \\ \\ {(x - 1)}^{2} + {(y + 2)}^{2} = 9 \\ \\ {(x - 1)}^{2} + {(y + 2)}^{2} = {3}^{2} \\ \\ equating \: it \: with \\ \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ \\ h = 1 \\ k = - 2 \\ r = 3 \\ \\ center = \boxed{1} \: \boxed{ - 2} \: \: radius = \boxed{3}$

MrMuchimi

20,000 x 25 = 500,000
500,000 divided by 100 = 5,000 members are lost.
Members left = 15,000
Members added = 10,000
Members every year = Members left + Members added
= 15,000 + 10,000
= 25,000
