Answer:
]-∞ , - 2[U] - 2,+∞[ answer : C
Step-by-step explanation:
hello :
R(x) = 3x/ x+2
R exist : x+2 ≠ 0 means : x ≠ -2
so the domain is : ]-∞ , - 2[U] - 2,+∞[ answer : C

k(x,9) = (-10,-6)
k*x = -10
k*9 = -6 Distributive property of multiplication
k*9 = -6
k = -6/9
k = -2/3 Get the value of k to solve for the value of x.
k*x = -10
-2/3 * x = -10
x = -10 ÷ -2/3
x = -10 * -3/2
x = (-10 * -3)/2
x = 30/2
x = 15 Choice D.
Answer:
3
Step-by-step explanation:
Answer:
y = -3x - 9
Step-by-step explanation:
Point-slope equation for line of slope -3 that passes through (-2,-3):
y+3 = -3(x+2)
Rearrange equation to slope-intercept form
y+3 = -3x - 6
y = -3x - 9
