Answer:
x = -2
Step-by-step explanation:
Solution:
-5x - 5y = 25 -(1)
3x + 5y = -21 -(2)
Adding (1) and (2),
-5x - 5y + 3x + 5y = 25 - 21
-5x + 3x -5y + 5y = 4
-2x = 4
x = 4 / -2
Therefore, x = -2

Answer:
116
Step-by-step explanation:
If we assume the quotient is px³+qx²+rx+s
Then the following must hold:
(px³+qx²+rx+s)(x+1) + 14 = x⁴ + ax² - 16
From this we can establish p,q,r and s and then a. Do the multiplication, and then find that:
p=1
p+q=0
q+r=a
r+s=0
s+14=-16
Combine these, and get:
s = -30
r = 30
q = -1
a = 29
Now that we have a, we can do a normal factorization:
(x⁴ + 29x² - 16) = (x³ + 2x² + 33x + 66)·(x-2) + 116
F(x)=|x|+7 is the equation
Answer:
65+x=150
he has 65 so if he keeps adding to it which is x and then he will get 150.
Answer:
B.) Transitive Property of Congruency; If parallel lines have a transversal, then alternative interior angles are congruent.
Step-by-step explanation:
Alternate interior angles are the two angles that are inbetween the parallel lines but are on opposite sides of the transversal. Angles 4 and 5 are alternate interior, and therefore, they are congruent.
