Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 8 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (6, - 6) into the partial equation
- 6 = - 3 + c ⇒ c = - 6 + 3 = - 3
y = -
x - 3 ← equation of line k
3x+9=5
3x=-4
x=-4/3
8z-1=11
8z=12
z=12/8
z=3/2
Hope u can do rest
Answer:
5:7
Step-by-step explanation:
140% of 30 is 42 so when i got that, i set up my proportion as 30:42 and then simplified
