Answer:
y=0 and x=5
Step-by-step explanation:
multiplying equation 2 by 7 and subtracting it from equation 1 we get
7x-2y=35 - 7x-28y=35
26y=0
y= 0/26
y = 0
putting value of y in equation 1
7x -2(0) = 35
7x - 0 = 35
7x = 35
x = 35/7
x = 5

When given 3 triangle sides, to determine if the triangle is acute right or obtuse
square all 3 sides
sum the squares of the 2 shortest sides
compare this sum to the square of the 3rd side
if sum > 3rd side squared it's an acute triangle
if sum = 3rd side squared it's a right triangle
if sum < 3rd side squared it's an obtuse triangle
24 32 42
24*24 = 576
32*32 = 1,024
42*42 = 1,764
Sum of the square of 2 shortest sides = 1,600
Since 1,600 < 1,764 these sides form an obtuse triangle.

Negative because it’s going “ down “
They do not intercept they are both straight horizontal lines one Where y is always equal to 4 and the other 5
