Answer:
the third one!
Step-by-step explanation:
Because it says, the SUM of the number, x (or z I can't really see it well) and 1/2, you must add those two together:
1/2 + x
Then it says those two numbers equal to 4, so it would look like this:
1/2 + x = 4
Because you are trying to isolate, and solve for x, you must SUBTRACT 1/2 from both sides of the equal sign:
1/2 + x = 4
-1/2 -1/2
1/2 minus 1/2 would result 0, so there would be x by itself. and 4 minus 1/2 would be 3 and a half ( 3 1/2), so x would be 3 1/2
x = 3 1/2
Hope this helped. If this is incorrect please specify so I can help :)
Answer:
f(x) = 0.5x will have a slope of 0.5.

(6,7)
Step-by-step explanation:

#4
Examine the relationship between y and x, waiting until later to examine the y-intercept. For example: If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table. If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.
Also note that all y values in the table are positive, so a negative slope would be inappropriate. That eliminates choices A and D.
Focus now on the remaining choices B and C. Again, let x= 2 and determine the associated y value. Which y value is closer to the table's 6.5?
B: 0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)
C: 3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)
C is the correct answer.
100 times, because 5 times 100 equals 500
