Mathematics

Answer:

23 units

Step-by-step explanation:

Use the distance formula: d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

Plug in the 2 points:

d = \sqrt{(-12 - 11)^2 + (-4 + 4)^2}

d = \sqrt{529}

d = 23

So, the distance is 23 units

Answer:

length of the line segment =23

Step-by-step explanation:

(11, −4)  = (x_1 , y_1) \\ (−12, −4) = (x_2 , y_2) \\ d =  \sqrt{(x_2  -  x_1)^{2}  + (y_2 - y_1)^{2} }

Plug in the values into the equation

d =  \sqrt{( - 12 - 11)^{2}  + ( - 4 - ( - 4)^{2} }

Simply :

-12-11=- -23

-4(-4) = -4+4=0

d =  \sqrt{( - 23)^{2}  +  {(0)}^{2} }  \\ d =  \sqrt{529 + 0}  \\ d =  \sqrt{529}  \\ d = 23

4/7 - x = 6/35 what is x? how do I determine the answer?
vivado [14]
4/7 - x = 6/35

You're trying to get x by itself, so you have to subtract 4/7 from both sides.

-x = 6/35 - 4/7

You need both of the fractions to the right of the equal sign to have the same denominator so that we could simplify them, so multiply 5/5 to -4/7.

-4 /7 × 5/5 = -20/35

So, our new equation is :

-x = 6/35 - 20/35

Simplify.

-x = -14/35

Divide both sides by -1.

x = 14/35

Divide by 7.

x = 2/5

Solve 3(a + 3) – 6 = 21.
tester [92]

Answer:

a=6

Step-by-step explanation:

to find the value of a you need to simplify the equation first. so...

3(a+3)-6=21 (you remove the bracket first)

3a+9-6=21

3a+3=21 (you collect the like terms then)

3a=21-3

3a=18 (then you both divide both sides by 3 to find the value of a)

a=18/3

a=6

to check your answer substitute 3 instead of a

3(a+3)-6=21

3(6+3)-6=21

3(9)-6=21 (according to BODMAS since multiplication comes first you multiply 3 with 9 before subtracting it from 6.)

29-6=21

21=21

Let the other number be y.

Given x + y = 49

x+y-x = 49 - x

y = 49 - x
