Distance Formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(-2, 1)

Point B(1, -1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Answer 2

Answer:

3.6 units

Step-by-step explanation:

Point A --> [tex]x_{1} \\[/tex] = -2 , [tex]y_{1}[/tex] = 1

Point B --> [tex]x_{2}[/tex] = 1   , [tex]y_{2}[/tex] = -1

AB =

[tex]\sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2 } \\\sqrt{[1 - (-2)]^2 + [(-1) - 1]^2} \\\sqrt{3^2 + (-2)^2} \\\sqrt{9 + 4} \\ \sqrt{13} \\3.605[/tex]

distance between AB can be rounded to 3.6 units

Hope it helps.

Write the equation of a line parallel to and passes through the given line’s x-intercept. Leave answer
in slope-intercept form

Answers

Answer:

y = 1/2x - 4

Step-by-step explanation:

The x-intercept is when y = 0, so it would be:

-x  + 2 * 0 = 4

-x = 4

x = -4

That means the x-intercept is (0, -4)

The parallel line would have the same slope as this one, so:

[tex]-x+2y = 4\\2y = x + 4\\y = 1/2x + 2[/tex]

The parallel line has a slope of 1/2

So now you need to find the equation of a line that has a slope of 1/2 and passes through the point (0, -4)

Put it in point slope form:

y - (-4) = 1/2(x - 0)

y + 4 = 1/2x

y = 1/2x - 4

If 2/3z = 6, then z=

Answers

Answer:

z=9

Step-by-step explanation:

we are given: 2/3z=6

we need to find what z is by itself

6 is 2/3rds of what the value of z is.

to find z, we need to multiply both sides by 3/2 (the reciprocal of 2/3z, to make the coefficient of 1)

3/2*2/3z=6*3/2

z=9

hope this helps :)

z = 9

Step-by-step explanation:

2/3 . z = 6

2z/3 = 6

Multiple all terms by the same value to eliminate fraction denominator,

3 x 2z/3 = 3 x 6

2z = 18 ( 3,3 got cancelled)

Divide both sides of the equation by the same term,

2z/2 = 18/2

On Simplify,

z = 9.

*(2,2 gets cancelled and 18/2 = 9)

When 6 is added to four times a number, the result is 50​

Answers

x=the number
4x+6=-50
4x=-50-6
4x=-56
x=-56/4
x=-14

Answer:

50-6= 54

54÷4= 13.5

editing for clarity.

first you subtract the 6 from the 50 to find out what the "4 times a number" came to.

in this case, 50-6, which equals 54.

then, you divide the 54 by 4 to get 13.5.

so, the whole math problem would be

4 times 13.5 plus 6 equals 50.

Answer:

No im pretty sure its not a solution.

Step-by-step explanation:

See if “z” is 2 than the answer to the solution would be 20

Answer:

The solution is -2

Step-by-step explanation:

4z + 12 = 4

4z = -8

Divide 4 on each side (4z / 4 = -8 / 4)

z = -2
