Answer:
The answer is y=x^2-2
Step-by-step explanation:
A linear function is a straight line when you graph it out. All the choices give you a straight line except for y=x^2-2. Therefore, that is the answer.

Answer:
25
Step-by-step explanation:
The median of a trapezoid equals one half of the sum of the bases
AC is a median and EB and DF are the bases.
hence AC = 1/2(EB + DF)
We are given that EB = 13 and that AC = 19. And we need to find DF
To do so we plug in what we are given and solve for DF
AC = 1/2(EB + DF)
AC = 19, EB = 13
19 = 1/2(13 + DF)
Now solve for DF
* Multiply both sides by 2*
19 * 2 = 38
1/2(13 + DF) * 2 ( the 1/2 and 2 cancel out and we're left with 13 + DF )
We then have 38 = 13 + DF
* Subtract 13 from both sides *
38 - 13 = 13 - 13 + DF
We get that DF = 25
Answer:
Choose the first one and second and the last one.
Step-by-step explanation:
This is an simple
Question 3) 5x-26=18x This is how the equation is written if you substitute numbers for words and x for unknown number. 18x-5x =13x divide everything by 13 to get x= -2
Question 4) 63-x=2x+3 add x to each side and subtract 3 from each side to get 60=3x divide by 3 to get x=20
Question 5) -30x= -27x-63 add -27x to each side to get -3x= -63. Divide everything by -3 to get x=21
Question 6) 12x-18= 18+13x subtract 12x from both sides to get -18=18+x subtract 18 from both sides to get x=-36
Hope this helps!
