Solve for X. 20 points !!!!
GarryVolchara [31]

Answer:

4) x = - 12

5) x = 4

Step-by-step explanation:

4)

Since points T and S are mid points of sides ML and MN of triangle MLN.

Therefore, by mid point theorem,

TS is half of LN

so,

x + 26 =  \frac{1}{2} (x + 40) \\  \\ 2(x + 26) =x + 40 \\  \\ 2x + 52 = x + 40 \\  \\ 2x - x = 40 - 52 \\  \\ x =  - 12

5) In the same way x = 4 will be the correct answer in question number 5.

KIM [24]

A line and a point can be collinear” is correct about a line and a point.

 

In geometry a line:

<span>

• has no thickness, and 
• extends in both directions without end (infinitely). </span>

 

In modern mathematics, a point refers usually to an element of some set called a space. More specifically, in Euclidean geometry, a point<span> is a primitive notion upon which the geometry is built.</span>

What would the slope intercept equation of the line shown below​
Olenka [21]

Answer:

y = -2x - 4.

Step-by-step explanation:

The points marked are (-2,0) and (0,-4).

The slope of line =  (-4-0) / (0- -2)

= -4/2 = -2.

The y-intercept is at y = -4,

so the equation required is y = -2x - 4.
