Answer:

The length= 16cm

The width= 6cm

The two long sides are 8cm both so 8 + 8 = 16

And the two short sides are 3cm both so 3 + 3 = 6

So your length should be 16cm and your width 6cm

Find the value of x L 7x-7 M 4x+14

Answers

Answer:

x= 7 sorry if I'm wrong:(

Step-by-step explanation:

7x - 7 = 4x + 14

7x - 7 - 4x = 4x + 14 - 4x

3x - 7 = 14

3x - 7 + 7 = 14 + 7

3x = 21

x = 21/3

x = 7

please help with solving this

Answers

Answer:

x=-7

Step-by-step explanation:

5x-2x+1=3x-6-x first combine like terms

3x+1=2x-6 combine like terms by subtracting 2x from both sides

x+1=-6 subtract 1 from both sides

Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)

Answers

answer would be “y=4”

to find the answer: first you have to find the slope with the given points. (y2 - y1 / x2 - x1)

plug it in to get: (4-4 / 1- -3) = 0/4 = 0

this means the slope would be 0

if the y intercepts are the same then it usually indicates that the slope would be 0 and that the answer is the y intercept.. but if you don’t understand how to get slope-intercept using other coordinates then here’s how:

you can use point-slope formula (y-y1 = m (x-x1) in order to do this just plug in one of the coordinates. in this case an example of point-slope form would be:
y-4 = 0 (x - -3) or y-4 = 0(x-1)

it doesn’t matter which coordinates you use..

then solve the point slope for slope-intercept.

y-4 = 0(x-3) multiply 0 with x and -3
y-4 = 0x move -4 to the right by adding 4

y = 0x + 4 or y = 4 would be your answer!

The equation for the line that passes through the point A ( -3 , 4 ) and

B ( 1 , 4 ) is y = 4

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the first point be A ( x₁ , y₁ ) = A ( -3 , 4 )

Let the second point be B ( x₂ , y₂ ) = B ( 1 , 4 )

Now ,

The equation for the line is given by

y - y₁ = m ( x - x₁ )

To find the slope of the line ,

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values , we get

m = ( 4 - 4 ) / 1 - ( - 3 )

m = 0

So , the slope of the line is 0

Now ,

The equation of line will be

y - 4 = 0 ( x - ( -3 ) )

y - 4 = 0

Adding 4 on both sides , we get

y = 4

So , the equation of the line is y = 4
