determine the equivalent system for the given system of equations.
4x − 5y = 2
10x − 21y = 10

a) 4x − 5y = 2
3x − y = 4

b) 4x − 5y = 2
24x − 47y = 22

c) 4x − 5y = 2
10x + 3y = 15

d) 4x − 5y = 2
14x + 26y = 12

The correct answer is B) 4x − 5y = 2

                                       24x − 47y = 22

Step-by-step explanation:

I took the test and got it right.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
