Okay to split a segment in half you just need to find the midpoint of the two endpoints. Mathematically this is just the average of the coordinates of the endpoints which is:

mp=((x1+x2)/2, (y1+y2)/2)

Which in this case is:

mp=((-2+3)/2, (4+7)/2)

mp=(1/2, 11/2)

mp=(0.5, 5.5)

So the x-coordinate by itself is just 0.5, or answer c.

The perimeter is 40. How much bigger is the longest side than the shortest side?

sesenic [268]

Answer:

10

Step-by-step explanation:

40=2a<u>-3</u>+2a+3a<u>+1</u>

add like terms

40=7a-2

get 'a' by its self

40(+2)=7a<u>-2(+2)</u> [2 cancels out]
42(÷7)=7a(÷7) [7 cancels out]
a=6

plug in the answer for Equations

biggest: 3(6)+1= 18+1= 19
smallest: 2(6)-3= 12-3=9

subtract smallest from biggest

19-9=10

Which point of intersection is the solution to the system of equations

Softa [21]

Answer:

B

Step-by-step explanation:

(Looking at the lines in the graph, the second equation is missing a minus sign, and should be $y=-\frac{1}{3}x + \frac{2}{3}$ )

To find the intersection point of the pair of linear equations, we just need to equate both values of y.

The equations are:

$y=\frac{2}{5}x - \frac{1}{2}$

$y=-\frac{1}{3}x + \frac{2}{3}$

Making the y from one equation equal the y of the other equation, we have:

$\frac{2}{5}x - \frac{1}{2} = -\frac{1}{3}x + \frac{2}{3}$

$\frac{2}{5}x +\frac{1}{3}x = \frac{2}{3} + \frac{1}{2}$

$\frac{6}{15}x +\frac{5}{15}x = \frac{4}{6} + \frac{3}{6}$

$\frac{11}{15}x = \frac{7}{6}$

$x = \frac{7}{6} * \frac{15}{11} =\frac{35}{22} = 1.591$

Then the y-coordinate of the point is found using this x-value in any of the two equations:

$y=\frac{2}{5}\frac{35}{22} - \frac{1}{2}$

$y=\frac{7}{11} - \frac{1}{2}$

$y=\frac{14}{22} - \frac{11}{22}$

$y=\frac{3}{22} = 0.136$

So the coordinate of the crossing point is (1.591, 0.136)

The point that is in this coordinate in the graph is point B.
