Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
4x+y=17;4x−3y=−3
Step: Solve4x+y=17for y:
4x+y+−4x=17+−4x(Add -4x to both sides)
y=−4x+17
Step: Substitute−4x+17foryin4x−3y=−3:
4x−3y=−3
4x−3(−4x+17)=−3
16x−51=−3(Simplify both sides of the equation)
16x−51+51=−3+51(Add 51 to both sides)
16x=48
16/x = 48/16
(Divide both sides by 16)
x=3
Step: Substitute 3 for x in y=−4x+17:
y=−4x+17
y=(−4)(3)+17
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5
So I think it is Dwat u think it is
Answer:
3/10 simplified
Step-by-step explanation:
120/400 simplified is 3/10 (divide both numbers by 40).
Answer:
Option A. 
Step-by-step explanation:
we know that
If triangle ABC is a right isosceles triangle
then
AB=AC
m<ABC=m<ACB=45°
therefore
The coordinate of point C is 
the x-coordinate of the midpoint M is equal to
The coordinates of point M are
Answer:
x=7, and y=3 is the answer..
