Answer:
x=2; y=1
Step-by-step explanation:
Since the triangle is equilateral, which means three sides have the same length.
So we have：4x-y=2x+3y=7
Since 2x+3y=7 and plug in x=2y
we have
and since y=1
x=2
y=−13
These are the x
and y intercepts of the equation y+1=3(x−4)
.
x-intercept: (133,0)
y-intercept: (0,−13)
so the correct answer is 3³
5
ALL SIDES MUST BE THE SAME
proportion used: 7/20
7emails were from the same person
35/100= 7/20
7/20 of 20
20/20=1
1x7= 7
