You have to make sure that whatever you do to one side, you also do to the other.
2x + 37 = 8x + 7
2x + 37 - 2x = 8x + 7 - 2x
37 = 6x + 7
37 - 7 = 6x + 7 - 7
30 = 6x
30 / 6 = 6x / 6
5 = x
x = 5
Hope this helps! :)
Answer:
A ) y=-1/2x+2
Step-by-step explanation:
since the equation is y=2x+4 and the points are (-2,3) and the line is perpendicular to that equation
y=-1/2x+b
enter the point (-2,3)
3=1+b
b=2
so
y=-1/2x+2

is true if either of

or

is true. We know

is true, which enough to say that

is also true.
Answer:
y = 
Step-by-step explanation:
to get the hypotenuse:
use the Pythagorean theorem:
a² + b² = c²
where a = 19, b = 8.2 c = y
plugin values:
19² + 8.2² = y²
y =
