A. Four times a number increased by two is equal to twice the difference between the number and three
Answer: See below
Step-by-step explanation:
Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7)
A)
B) Slope of AB line = m₁=3/2
Slope of BC line = m₂=-2/3
Slope of CA line = m₃=-5
C) 
Therefore, the triangle is a isosceles right angle triangle
I believe the answer is 644=200+12a
-10(1) = w + 5.3
-10 = w + 5.3
-10 (-5.3) = w + 5.3 (-5.3)
w = -15.3
hope this helps
Answer:
37
Step-by-step explanation:
f(x) = 2x-1
g(x) =x^2 +3
f°g(x) = means put g(x) in for x into the function f(x)
f(g(x)) = 2 (g(x)-1
=2(x^2 +3) -1
Distribute
= 2x^2 +6-1
=2x^2 +5
Now we let x=-4
f(g(-4)) = 2 (-4)^2 +5
=2(16) +5
=32+5
=37
