write the statement as an equation as an equation in two variables the y-value is -5 decreased by six times the x-value

Sergio [31]

For this case we have the following statement:

"the y-value is -5 decreased by six times the x-value"

We must write the equation in algebraic form.

We have then:

the y-value is: y =
-5: -5
decreased by: -
six times the x-value: 6x

Rewriting we have:

$y = -5-6x$

Answer:

the statement as an equation is:

$y = -5-6x$

Find the ratio AP/PB for 100 points ASAP

shtirl [24]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

To find the ratio of AP/PB, find the distance between A and P, then P and B.

Distance between A(-5, 6) and P(1, 4):

$AP = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$A(-5, 6) = (x_1, y_1)$

$P(1, 4) = (x_2, y_2)$

$AP = \sqrt{(1 -(-5))^2 + (4 - 6)^2}$

$AP = \sqrt{(6)^2 + (-2)^2}$

$AP = \sqrt{36 + 4} = \sqrt{40}$

Distance between P(-1, 2) and B(1, -2):

$PB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$P(1, 4) = (x_1, y_1)$

$B(13, 0) = (x_2, y_2)$

$PB = \sqrt{(13 - 1)^2 + (0 - 4)^2}$

$PB = \sqrt{(12)^2 + (-4)^2}$

$PB = \sqrt{144 + 16} = \sqrt{160}$

$\frac{AP}{PB} = \frac{\sqrt{40}}{\sqrt{160}}$

$= \frac{\sqrt{40}}{2\sqrt{40}}$

$= \frac{1}{2}$

I think this is the hardest question But if you solve this you will get 500+ points

blondinia [14]

Answer:

Step-by-step explanation:

Let the number of 20cent coins be 'x'

Then, 10cent coins are 'x + 12'

Total amount = $5.4 = 540 cents

20(x) + 10(x + 12) = 540

20x + 10x + 120 = 540

30x = 540 - 120

30x = 420

x = 420/30

x = 14 (14 20cent coins)

x + 12 = 26 (26 10cent coins)

Total coins = 14 + 26 = 40
