to solve this system I first multiplied the second equation by 2 to make the x coefficient equal. then I subtracted equation two from equation one. this eleminated the x. solving for y gave me y=0. then I put 0 back in the original equation and that gave me x=-4.
Answer:
a) (3, 0), (0, -2)
b) see below
Step-by-step explanation:
The x-intercept is found by setting y=0 and solving for x:
2x = 6
x = 6/2 = 3 . . . point (3, 0), x-intercept
The y-intercept is found by setting x=0 and solving for y:
-3y = 6
y = 6/-3 = -2 . . . point (0, -2), y-intercept
__
The graph is the line through these points.
Answer: For this case we have the following expression:
We must factor the term that accompanies the variable.
We have then:
Rewriting the expression we have:
We're going to check the result. To do this, we multiply the term 3/8 for each term within the parenthesis:
Rewriting:
The factorization is correct.
Answer:
(3/8) (d + 2)
Hope this helps... Stay safe and have a great rest of the day... :D
