The answer is: 1 + 5a ; or, 5a + 1 .
______________________________
Given the expression:
______________________________
<span>1 + 10a − 5a ;
________________
→ We identify the "like terms" ;
___________________________
→ which are "10a" and ( "-5a") ;
____________________________
→ 10a </span>− 5a = 5a ;
_________________________________
→ 1 + 5a ; is the most simplified; or write the expression as: 5a +1 .

Answer: OPTION B.
Step-by-step explanation:
1. By definition, the line intercepts the x-axis when y=0. Therefore, you must susbtitute y=0 into the equation of the line given in the problem and solve for x, as you can see below:
2. Knowing that the x-intercept of the line from the equation and is -2 and the x-intercept from the description is (0,0), you can conclude that the correct option is B.
Answer:
(2, 5)
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
- 2x + y = 1 → (2)
Substitute y = x + 3 into (2)
- 2x + x + 3 = 1
- x + 3 = 1 ( subtract 3 from both sides )
- x = - 2 ( multiply both sides by - 1 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 2 + 3 = 5
Solution is (2, 5)
Every proportional relationship is an equation like y = a number times 'x'. When you graph that equation it's a straight line that goes through the origin and every point on the line satisfies the equation. Line B is the only graph that looks like that. The others all have a piece of a proportional relationship. Their bottom pieces are proportional relationships but then they break and the top pieces are not.
