Answer:

a. x/y = 2 b) y/x +y =1/3 c) x-y/y= 1 d) y/x = 1/2

Step-by-step explanation:

Solve for

a) x/y

as we know x +y/y = 3

x+y= 3y

x= 3y-y

x= y(3-1)

x/y= 3-1

x/y = 2

b) y/x+y

as we know x +y/y = 3

x+y = 3y

1= 3y/x+y

1/3 = y/x+y

So y/x +y =1/3

C) x-y /y

as we know x +y/y = 3

x +y = 3y

subtracting 2y from both sides

x +y -2y = 3y- 2y

x-y = y

dividing both sides by y

x-y/y = y/y

x-y/y= 1

d) y/x

as we know x +y/y = 3

x +y = 3y

x= 3y- y

x= 2y

dividing both sides by x

x/x = 2y/2x

1 = 2 x (y/x)

1 / 2 = y/x

Or y/x = 1/2

Best of luck.

Answer:

Hi , the answer is 280-140/ 4-2 = 140/2

y = 2/140 x

b . 70 beats each minute

Step-by-step explanation:

we will take a 2 point from the graph

(280,4) , (y1,x1) and (140, 2) , (y2,x2) each point represent a (y,x) point

m = y1-y2 / x1-x2 = 280-140 / 4-2 = 140 /2

now , y/x = 140/2 ... by B. Multiplication we will get y = 2/140 x

b .

from the graph we see that every minute the curve increase 70 beats

Vertical? Supplementary? Right? Complementary?

Reika [66]

Answer:

Step-by-step explanation:

because we know that angle EOD is less the 90 so that means that it is complementary. For AOB it is the same but we can check by adding 35 plus x plus 90 =180 degrees so 35+90=125 x=180-125=55 so x=55 and 55 is less then 90 so it is a complementary angle.

Brian, Kelsey, and Geoff each have a remote-controlled car. They simultaneously started their cars and drove them in a straight

jasenka [17]

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the Brian, Kelsey, and Geoff each have a remote-controlled car. They simultaneously started their cars and drove them in a straight line away from a motion sensor.

It means they are travelling at a constant rate.

Slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

From the given table it is clear that the of Brian's car from the sensor is 34 at 1 sec and 38 at 3 sec. The rate of change is

$m=\frac{38-34}{3-1}=2$

It means the Brian's car traveled at the rate of 2 cm per sec.

From the given table it is clear that the of Brian's car from the sensor is 27 at 1 sec and 31 at 3 sec. The rate of change is

$m=\frac{31-27}{3-1}=2$

It means the Kelsey's car traveled at the rate of 2 cm per sec.

From the given table it is clear that the of Brian's car from the sensor is 27 at 1 sec and 33 at 3 sec. The rate of change is

$m=\frac{33-27}{3-1}=3$

It means the Geoff's car traveled at the rate of 3 cm per sec.

Since Brian's and Geoff's car traveled at the same rate, therefore option 1 is correct.
