Add 3 on both sides
8y - 3 + 3 = 13 + 3
8y = 13 + 3
8y = 16
Divide 8 on both sides
8y/8 = 16/8
y = 16/8
y = 2
y = 2
Answer:
it is negative
Step-by-step explanation:
a negative plus a negative make a more negative number
A. (f + g)(x) = f(x) + g(x) = 4x - 5 + 3x + 9 = 7x + 4
B. f.g (x) = f(x) * g(x) = (4x - 5)*(3x + 9) = 12x^2 + 36x - 15x - 45
= 12x^2 + 21x - 45
C Replace the x in f(x) by g(x):-
= 4(3x + 9) - 5
= 12x + 36 - 5
= 12x + 31
Answer:

Step-by-step explanation:
negative + negative is positive
Answer:
The perpendicular line 4x − 5y = 20 has a slope of 4/5 and as such, the slope of the required line = -5/4
(y - 3)/(x + 4) = -5/4 simplify to get the required equation: 5x + 4y + 8 = 0
