Hi there!
![- 2a(a + b - 5) + 3( - 5a + 2b) + b(6a + b - 8)](https://tex.z-dn.net/?f=%20-%202a%28a%20%2B%20b%20-%205%29%20%2B%203%28%20-%205a%20%2B%202b%29%20%2B%20b%286a%20%2B%20b%20-%208%29)
First work out the parenthesis.
![- 2 {a}^{2} - 2ab + 10a - 15a + 6b + 6ab + {b}^{2} - 8b](https://tex.z-dn.net/?f=%20-%202%20%7Ba%7D%5E%7B2%7D%20-%202ab%20%2B%2010a%20-%2015a%20%2B%206b%20%2B%206ab%20%2B%20%7Bb%7D%5E%7B2%7D%20-%208b)
Now collect the terms.
![- 2a {}^{2} + {b}^{2} + 4ab - 5a - 2b](https://tex.z-dn.net/?f=%20-%202a%20%7B%7D%5E%7B2%7D%20%2B%20%7Bb%7D%5E%7B2%7D%20%2B%204ab%20-%205a%20-%202b)
Next up we can answer our questions.
The coefficient of the a^2 term is...
B) -2
The coefficient of the ab term is...
B) 4
The coefficient of the b term is...
A) -2
Answer: 3x+1
Step-by-step explanation: you add the x value together & then you find the sum for 1,2, and -2
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (10, 1) into the partial equation
1 = 30 + c ⇒ c = 1 - 30 = - 29
y = 3x - 29 ← in slope- intercept form
Subtract y from both sides
0 = 3x - y - 29 ( add 29 to both sides )
29 = 3x - y, thus
3x - y = 29 ← in standard form → B
The answer is going to be 10/3. hope that helped
Answer:
1 1/3
Step-by-step explanation:
Change 3/4 to 9/12 and then add 9/12 and 7/12.
You get 16/12 and then simplify it by dividing it by 4.
