C is on the line and D is not on the line.
-1/2(-40)+1=21
-1/2(20)+1≠-11
Answer:
B
Step-by-step explanation:
4x + 2y = 3
(send 2y to the right and 3 to the left)
4x - 3 = -2y
(divide everything by -2)
(4x)/(-2) - 3/(-2) = y
So now we have a function which is like
y = ax + c
c = the y value of intersection point of the equation and the y-axis
a = amount of increase in y values per x value
so in this example:
(4x/(-2)) = (4/(-2))x -> a = 4/(-2) = -2
and
c = -3/-2 = 3/2
So the graph that we're searching for is increasing (-2) y values (so decreasing 2 y values) per 1 x value and has an intersection with the y-axis where y = 3/2
Step-by-step explanation:
The numerator of the exponent becomes an exponent. The denominator of the exponent becomes the index of the root.

282 I believe its a really long answer but to simplify just do the the brackets first so 64. Do all the multiplication next so 8x6 is 48, 4x7 is 28 and 4x64 is 256. Next do addition and subtraction. 48-3+256+9-28
