Answer:
Step-by-step explanation:
Add 4 to both sides
13 + 4 = w/-3 - 4 + 4
17 = w/-3 Multiply through by -3
17*-3 = -3*(w/-3)
-51 = w
Answer:
y = -2 ( (x^2) + (2*x*5) + (5^2)) - 30
y = -2 ( x^2 + 10x + 25) - 30
y = -2x^2 - 20x - (2*25) - 30
y = -2x^2 - 20x - 50 - 30
y = -2x^2 - 20x - 80
Answer:
2,5 then 17 20 then keep adding 15 for x and y
Problem: 2/7 (4+c)=6
1. 7/2 x 2/7 x (4+c)=7/2 x 6
2. 4+c=7 x 3
3. 4+c=21
4. c=21-4
Answer: c=17
The answer would be 8 do 9-1=8
