For a solution to exist for two lines, y=y so we can say:

-3=7x-10  add 10 to both sides

7=7x  divide both sides by 7

x=1

So the solution is the point (1, -3)

Construct a quadrilateral ABCD in which AB = 4 cm, BC = 7 cm, angle A = angle C = 105 degree
Lelu [443]

Answer: see attachment

<u>Step-by-step explanation:</u>

Since A = C = 105° and D = 60°,

then A + B + C + D = 360°

     105° + B + 105° + 60° = 260°

               B + 270° = 360°

                          B = 90°

A line has a slope of -2/5. Generate the coordinates of two points that would lie on the same line
vovangra [49]

Answer:

Many solutions are possible. One example is (10,5) and (5,7).

Step-by-step explanation:

The slope is the distance between points represented as a ratio of vertical to horizontal distances. It is a difference or subtraction. To find two points work backwards. What two points have y values with a distance of -2?

5-7=-2

So the points are (x,5) and (x,7).

Now what x values have a distance of 5?

10-5 = 5

So the points are (10,5) and (5,7).
