Answer:

y=5/4x+10

Have a nice day.

Answer:

5/4x + 10

Step-by-step explanation:

If it's parallel, the slope will remain the same.

To find the y-intercept, you have to plug in the coordinates into the equation which is, y = 5/4x + b.

y = 5/4x + b

0 = 5/4 (-8) + b

0 = -10 + b

10 = b

The equation is 5/4x + 10.

a shopkeeper sold an article for 450 at a loss 10% at what price should he sell it as to gain 10%?​

Answers

Answer:

The correct answer is "550". A further explanation is given below.

Step-by-step explanation:

The given values are:

Selling price,

= 450

Loss,

= 10%

Profit,

= 10%

As we know,

⇒  [tex]CP=\frac{100}{100-Loss \ percent}\times SP[/tex]

On substituting the values, we get

⇒         [tex]=\frac{100}{100-10}\times 450[/tex]

⇒         [tex]=\frac{100}{90}\times 450[/tex]

⇒         [tex]=500[/tex]

⇒  [tex]Profit=500\times \frac{10}{100}[/tex]

⇒              [tex]=50[/tex]

Now,

Selling price on 10% profit will be:

⇒  [tex]SP=CP+profit[/tex]

On substituting the values, we get

⇒        [tex]=500+50[/tex]

⇒        [tex]=Rs. \ 550[/tex]

A = 250

B = 10

Step-by-step explanation:

Why A equals 250 is because 10 squared 5 equals 500 and 500 divided by 2 equals 250.

Why B equals  10 is because 10 minus 5 is 5 we do that first cause its in pentises and 10 squared times 2 equals 200 and 200 times 5 equals 1000 so 1000 divide 100 is 10

. A football team had 52 players at the start of the season, but then some players left the team. After that, the team had 43 players.​

Answers

Answer:

[tex]52-p<43[/tex]

Step-by-step explanation:

There was a total of 52 players but then some left the team. Since we don't know how many left, we use a variable. Left indicates subtraction, so the equation would be 52 - p.

However we still have the last sentence of the information. Since 43 players remain and we don't know how many players left, I put the '<' sign.

Thus, my answer was: [tex]52-p<43[/tex]

Step-by-step explanation:

Usually, when we say two objects are related by a scale factor, we are talking about the linear dimensions  of the objects. Here, we're concerned with the ratio of diameters. The diameter is a linear dimension of the sphere, so the ratio of diameters is the same as the scale factor:

f(x) = 3(x-8)(x + 2)

Answers

Answer:

x = 39

Step-by-step explanation:

In the image, in order for DE to be parallel to CB, the scale factor between AE and EB should be the same as between AD and DC. To solve this, you first need to identify these lines:

AE = 12, EB = x - 3

AD = 6, DC = 18

Now, you need to find the scale factor by dividing 18 by 6:

18 ÷ 6 = 3

So the scale factor from AD to DC is 3. This means that the scale factor from AE (12) to EB should also be 3. You can find x by writing and solving an equation:

12 × 3 = x - 3 (given)

36 = x - 3 (simplify)

x = 39 (add 3 to both sides)

So x = 39.

what is the value of the fourth term in a geometric sequence for which a1=30 and r=1/2

Answers

Answer:

a(4) = 15/4

Step-by-step explanation:

The general formula for a geometric series with common ratio r and first term a(1) is

a(n) = a(1)*r^(n - 1)

and so, if a(1) = 30 and r = 1/2, we have

a(n) = 30*(1/2)^(n - 1)

and the fourth term is then:

a(4) = 30*(1/2)^(4 - 1) = 30/8 = 15/4
