Answer:
Jenna is correct.
Step-by-step explanation:
I will assume that is what you meant.
Jenna is correct .
The square root of 4 ( = 2) is rational but,
for example, 2 is a rational number but the square root of 2 is irrational. Try finding the square root of 2 on your calculator. Your answer will be something like 1.414213562 but that decimal fraction goes on without bounds. No calculator will ever have enough memory to store that number!!
So, pretend this is your x-axis and y-axis:
I
I
(-2,7) • I
I
I • (2, 5)
I
I
I
I
_________________I____________________
I

TO GET FROM POINT (-2, 7) TO POINT (2, 5), WE MOVE DOWN 2 AND OVER 4, SO THE SLOPE IS -1/2. IF WE FOLLOW THAT SLOPE AND MOVE DOWN 1 AND OVER 2 FROM THE FIRST POINT OF (-2, 7), WE WILL LAND ON A POINT LOCATED AT (0, 6), WHICH WOULD BE THE "Y-INTERCEPT". WE WERE JUST ABLE TO CALCULATE THE SLOPE OF THE LINE AND THEN USE THE SLOPE TO FIND THE INTERCEPT. SO, THE "SLOPE-INTERCEPT" FORM OF THE EQUATION FOR THIS LINE IS:
y = -1/2x + 6
TO RE-WRITE THIS IN STANDARD FORM, WE JUST WANT TO MOVE THE X VARIABLE OVER TO THE LEFT WITH THE Y VARIABLE, SO:
y = -1/2x + 6
+1/2x + 1/2x
1/2x + y = 6 .... and that is your answer!
Answer:
1/4
Step-by-step explanation:
Substitute x=-1 to find y
Given y= 2^2x
y(-1)=2^-2=1/(2^2)
Answer:
C) 2 + 3 x - 18
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given expression 2+ 3(x-6)
⇒ 2 + 3 x - 18
⇒ 3 x - 16
