Well, we know that 25% is also 1/4 and if we multiply $80.00 by 1/4 you get $20 so the answer is $20.
Answer:
2) x = 6 y = 7 3) x = -5 y= 2
Step-by-step explanation:
2) 10x - 8y = 4
2(-5x + 3y = -9)
-10x + 6y = -18
10x - 8y = 4 Add both equations together
-2y = -14
y = 7 Divide both sides by -2
10(x) - 8(7) = 4 Plug in 7 for the y to solve for x
10x - 56 = 4
+ 56 + 56 Add 56 to both sides
10x = 60
x = 6 Divide both sides by 10
3) Where the two lines intersect, that is the solution to x and y.
The lines intersect at (-5,2). x = -5 y = 2
Answer:
Ok time to get math on
So this would be D
A non-filled in dot means < or > (depending where arrow is pointing)
A filled in dot means ≤ or ≥ (depending where arrow is pointing)
if an arrow points right, then it would be greater than, if arrow points left.. Then its less than
So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D
A is greater than which is not the answer
B is only equal to which is way off
C is less than but it is equal which is wrong
D is the only right answer
Hope this helps! :)
