John's age increased by 11 is 5 less than 5 times his age. How old is he?
babymother [125]

Answer:

x+11 = 5x - 5

Step-by-step explanation:

x+ 11 = 5 x − 5

Subtract  x from both sides

11 = 4 x− 5

Add  5  to both sides

16 = 4 x

MrRa [10]

Answer:

Option (2). None

Step-by-step explanation:

A quadrilateral ABCD has been given with a property,

m∠7 = m∠4

Option (1). AB║ DC

For AB║DC, angle 7 and angle 3 should measure the same.

(By the property of alternate angles)

Therefore, by the given property we can not deduce AB║DC.

Option (3). AD║BC

For AD║BC, angle 7 and angle 3 must be equal in measure.

(By the property of alternate angles)

Therefore, by the given property we can not deduce AD║DC

Option (2). None will be the answer.

What is the equation of a line which includes points (-5, 5) and (2, 5)?
sveta [45]
<h2>Hello!</h2>

The answer is:

The equation of the line which includes the points (-5,5) and (2,5) is:

y=5

<h2>Why?</h2>

To find the line which includes the points (-5,5) and (2,5) we can use the following equation:

y-y_1=\frac{y_2-y_1}{x_2-x_1}*(x-x_1)

So, using the points (-5,5) and (2,5), we have:

y-5=\frac{5-5}{2-(-5)}*(x-(-5))

y-5=\frac{0}{2+5}*(x-(-5))

y-5=0*(x+5)

y-5=0

y=5

We have that the equation of the line which includes the points (-5,5) and (2,5) is:

y=5

Have a nice day!
