Use elimination.
-x = -6
X = 6
-4 (6) + 4y = 12
Y = 9
(X,y)
(6,9) is the solution
Answer:
10
Step-by-step explanation:
h(x)=4x-2 h(x)=3
h(3)=4(3)-2 substitute
h(3)=12-2 multiply
=10 subtract
Answer:
yes

I'm ready to help anyone in maths
Answer:
200 √17
Step-by-step explanation:
distance between two points (x,y) and (x',y')
D² = (x' - x)² + (y' - y)²
D² = (500 - (-300))² + (400 - 200)² = 640000 + 40000 = 680000
D = √680000 = √4 x 17 x 10000 = 200 √17
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
