Answer:

the measure of AB equals the measure of BC

2x+1=3x-4

4+1=3x-2x

5=x

BC=3x-4=3*5-4=15-4=11

AB=2x+1=2*5+1=10+1=11

AC=AB+BC=11+11=22

Help pls asap!!!!! !!!!!
stiv31 [10]

Answer:

It is 40 degrees.

Step-by-step explanation:

You can start off by understanding this is not a right angle (exactly 90 degrees, think of a corner of a room) or and obtuse angle (more than 90 degrees, bigger than a right angle). With that information we know that it is an acute angle (less than 90 degrees, smaller than a right angle). With that we have 40 and 50 degrees left. When you compare the angle with the 40 degrees one, it is the same size. The angle 1 is a reflection of the triangle with the 40 degrees angle. Hope this helps :)

What is the solution of y= -5x + 1 and y= 3x - 2
Nezavi [6.7K]

Answer:

x=3/8, y=-7/8. (3/8, -7/8).

Step-by-step explanation:

y=-5x+1

y=3x-2

----------

-5x+1=3x-2

-5x-3x+1=-2

-8x+1=-2

-8x=-2-1

-8x=-3

8x=3

x=3/8

y=3(3/8)-2=9/8-2=9/8-16/8=-7/8

Determinewhether the two lines areparallel, perpendicular, neither.X-3=6Y = 3x +4
Brums [2.3K]

we have the lines

x-3=6

x=6+3

x=9

this is a vertical line (parallel to the y-axis)

The slope is undefined

and

y=3x+4

The slope is m=3

Compare their slopes

1) Their slopes are not equal -----> are not parallel lines

2) Their slopes are not negative reciprocal -----> are not perpendicular lines

therefore

<h2>The answer is neither</h2>
