Answer:
The coordinates of
are
and
.
Step-by-step explanation:
Let be
and
endpoints of segment AB and
a point located 7/10 the way from A to B. Vectorially, we get this formula:


By Linear Algebra we get the location of
:



If we know that
and
, then:




The coordinates of
are
and
.

Substitute the given value of y into the equation y=7x+15

Move the variable to the left-hand side and change its sign

Collect like terms

Divide both sides of the equation by -5

Substitute the given value of x into the equation y=2x

Solve the equation for y

The possible solution of the system is the ordered pair (x,y)

Answer:
x = 14.7
Step-by-step explanation:
law of sines:
sin 20°/7 = sin 46°/x
x ·sin(20°) = 7 ·sin(46°)
x = 7 ·sin(46°) / sin(20°)
x = 14.722
