Answer:Length of the line segment =23

Step-by-step explanation:

Given points: (11,-4) and (-12,-4)

Distance between two points is given by the distance formula

i.e. D=√ $(x2-x1)^{2}+(y2-y1)^{2}$

x1=11, y1=-4

x2=-12, y2=-4

Length of the given segment=√((-12-11)²+(-4-(-4))²)

D=-√((-23)²+0²)

D=√529

D=±23

D=23 [Since D can't be negative]

Use distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
(11,-4) is (x1,y1) and (-12,-4) is (x2,y2)
Plug in and simplify
d = sqrt((-12 - 11)^2 + (-4 - -4)^2)
d = sqrt((-23)^2 + (0)^2)
d = sqrt(529 + 0)
d = sqrt(529)
d = 23 (positive because length cannot be negative)

Collins is working.......

lesya [120]

Let n represent the amount Colin earned on Sunday.

On Sat. he earned n/2; on Sun. he earned n; and on Friday he earned (1/2)(n/2).

Then n/2 + n + n/4 = $70

Mult. all terms by 4 to eliminate fractions:

2n + 4n + n = $280

7n = $280 => n = $40

Colin earned n/2, or $20, on Saturday; n, or $40, on Sunday; and n/4, or $10, on Friday.

Note that $20 and $40 and $10 add up to $70, as they must.
