Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 2x + 6 → (1)
y = x + 2 → (2)
Substitute y = 2x + 6 into (2)
2x + 6 = x + 2 ( subtract x from both sides )
x + 6 = 2 ( subtract 6 from both sides )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 4 + 2 = - 2
solution is (- 4, - 2 ) → B
X=7/18+4/9
I’m pretty sure that’s the answer
1. Yes it shows proportional relationship because they go by 5.
2. okay.. so your answer choices are 3) 2, 4) 10, 5) -2, and 6) 8. I'M GONNA GUESS. it's going to be #3.
3. Okay so $100- 30 - 10 = $60 That means that each hat cost $6 dollars and he bought 10 of them so 10 times 6 equals 60.
4. they cost 4.50 because she bought ten of them so if you multiply 4.50 by ten you get 45 and she had 5 left over.
Hope this helped!

Please tell me which ones were wrong and which ones were right!
Answer:
The length of the third side AC = 3.60 inches
Step-by-step explanation:
Given first side of the length of the right angle triangle (AB )
a = 2 inches
Given second side of the length of the right angle triangle (BC )
b = 3 inches
By using Pythagorean theorem
AC² = AB² + BC²
c² = a² + b²
c² = 4 + 9
c² = 13
c = √13 = 3.60 inches
<u><em>Final answer:-</em></u>
<em>The length of the third side AC = 3.60 inches</em>
