Answer:
7/3
Step-by-step explanation:
or, 3x/4 - 7/8 = 7/8
or, 3x/4=7/8+7/8
or, 3x/4 = (7+7)/8
or, 3x/4 = 14/8
or, 3x = (14/8)*4
or, 3x=56/8
or, 3x= 7
or, x=7/3

Answer:
y=
Step-by-step explanation:
Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept
y=mx+b
2=
(8)+b
2=4+b
B=-2
y=
Answer:
x² - x - 12 = 0
Step-by-step explanation:
0 = -x² + x + 12
→ Add x² to both sides
x² = x + 12
→ Minus x from both sides
x² - x = 12
→ Minus 12 from both sides
x² - x - 12 = 0
