Answer:
x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.
Step-by-step explanation:
2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2
(2x - 3) • 2 = x + 9
4x - 6 = x + 9 Add 6 to both sides
4x = x + 9 + 6
4x = x + 15 Subtract x from both sides
4x - x = 15
3x = 15 Divide 3 on both sides
x = 15/3
x = 5
So you subsitute y=2/3x-4 for y in 2x+y=4 so
2x+(2/3x-4)=4
2x+2/3x-4=4
add like terms
2 and 2/3x-4=4
add 4 to both sidees
2 and 2/3x=8
2 and 2/3=6/3+2/3=8/3
8/3x=8
multiply both sides by 3/8 (makes 8/3=24/24=1/1=1)
x=(3*8)/8
simplify
x=3
subtitute x=3 into y=2/3x-4
y=2/3(3)-4
y=(6/3)-4
y=2-4
y=-2
