The length of a line is y centimetres.

Mathematics
1 answer:
ElenaW [278]3 years ago
3 0

Answer:

10y  mm

Step-by-step explanation:

We would need to know the conversion of cm to mm.

We know

1 cm = 10 mm

If we are given a certain amount of centimeters (cm), to get the answer in millimeters (mm), we multiply that by 10. Example:

1 cm = 10 mm

4 cm would be 4 * 10 = 40 mm

23 cm would be 23 * 10 = 230 mm

Now, we are given "y" centimeters.

So, we multiply by "10" to get the answer in millimeters.

Hence,

y * 10 = 10y millimeters (mm)

The line is 10y mm

Write the equation of a line perpendicular to 5x – 4y = - 3 that passes through the point (-5,2).
kolezko [41]

Answer: 5y + 4x = - 10

Step-by-step explanation:

Two lines are said to be perpendicular if the product of their gradients = -1.

If the gradient of the first line is m_{1} and the gradient of the second line is m_{2} , if the lines are perpendicular, them

m_{1} x m_{2} = -1 , that is

m_{1} = \frac{-1}{m_{2} }

The equation of the line given is 5x - 4y = -3 , we need to write this equation in slope - intercept form in order to find the slope.

The equation in slope -intercept form is given as :

y =mx + c , where m is the slope and c is the y - intercept.

Writing the equation in this form , we have

5x - 4y = + 3

4y = 5x -+3

y = 5x/4 + 3/4

comparing with the equation y = mx + c , then m_{1} = 5/4

Which means that m_{2} = -4/5 and the line passes through the point ( -5 , 2 ).

Using the equation of line in slope - point form  to find the equation of the line;

y - y_{1} = m ( x -  y_{1} )

y - 2 = -4/5 ( x +5)

5(y - 2 ) = -4 ( x + 5 )

5y - 10 = -4x - 20

5y + 4x = - 10
