Answer: 
Step-by-step explanation:
You need to remember the mulplication of signs:
Knowing this, you can distributive the negative sign. Then you get:
Now you need to add the like terms. Then:
Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:
Answer:
2 and 3 are the only true statements
Answer:
Step-by-step explanation:
-7x-3=2-7x-5
cancel equal terms
-3=2-5
calculate the difference
-3= -3
This statement is true.
Answer:
y = 2x − 6
Step-by-step explanation:
Answer:
y = x - 6
Step-by-step explanation:
the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.
now, let's calculate the slope:
1-2/7-8= -1/-1 = 1
here is the equation we currently have solved: y = x + b
now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.
let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.
2= 8 +b
2 -8=b
b=-6
and now we have our final equation!
y = x - 6
hope this helped! please let me know if you are confused about anything i did
