A. 12x+y=6<span>B. −2x+y=6</span>
Answer:
x = 7.2
Step-by-step explanation:
Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.
Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}
(Assuming x is greater than 1.7}
Given that, x + 3.8 = 2(x - 1.7)
⇒ x + 3.8 = 2x - 3.4
⇒ x = 7.2 (Answer)
Answer:
B. 8x + 56
Step-by-step explanation:
Answer:
hope this helps
Step-by-step explanation:
Substitute the x value in for x.
f(x) is also y
(x,y)
-2 squared is 4 = (-2,4)
-1 squared is 1 = (-1,1)
0 squared is 0 = (0,0)
1 squared is 1 = (1,1)
2 squared is 4 = (2,4)
