Answer:
1; -1
Step-by-step explanation:
As x approaches 0 from the left, the graph goes up to the point (0, 1), where the solid dot indicates that is the function definition for x=0.
As x approaches 0 from the right, the graph goes down toward the point (0, -1), to which it comes arbitrarily close. The limit from that direction is -1.
The two limits are +1 and -1.
a)no solution
b)d=4
c)infinitely many solutions
d)d=-3
Answer:
y = - 9x + 15
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 = - 9x - 2 ← is in slope- intercept form
with slope m = - 9
Parallel lines have equal slopes, thus
y = - 9x + c ← is the partial equation
To find c substitute (2, - 3) into the partial equation
- 3 = - 18 + c ⇒ c = - 3 + 18 = 15
y = - 9x + 15 ← equation of parallel line
