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 = 3x - 1 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (2, 2) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = 3x - 4 → B
Answer:
20
Step-by-step explanation:
To find x, note that:
<h3>
Vertically opposite angles are equal.</h3>
Therefore,
(2x + 20)° = 60°
Removing bracket.
2x + 20 = 60
collecting like term.
2x = 60 - 20
2x = 40
dividing bothsides by 2
2x/2 = 40/2
x = 20
