Answer:
Your answer is A.
Hope this helps!
Step-by-step explanation:
Line r's equation is
y = - 4/3x - 4
And Line s's equation is
y = 2/5x - 2
Answer:
(-4, 2) and (4, -5)
m = (-5 - 2)/(4 - (-4)) = -7/8
y = -7/8 * (x - (-4)) + 2
y = -7/8 * (x + 4) + 2
y = -7/8 * x - 3/2
Answer:
8.1
Step-by-step explanation:
2x^2 -9 = 121
+9 +9
2x^2 = 130
/2 /2
x^2 = 65
x= sqrt (65)
x= 8.06225...
x = 8.1
Answer: 9+4n-1 = 20
We can solve this by substitution.
Replace n with the value given, 3 (remember 4n means 4 times n):
9 + 4*3 - 1
Then work it out using arithmetic
9+12-1
=20
