Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
J (1, 4 ) → J' (- 1, 4 )
K (1, 0 ) → K' (- 1, 0 )
L (4, 3 ) → L' (- 4, 3 )
Plot the points J', K', L' and connect them in order to obtain image
Answer: -17 degrees
Step-by-step explanation:
109-126 = -17
Answer:
Below in bold.
Step-by-step explanation:
Let x be George's age and y be Genemy's age.
x/y = 5/7
(x + 4)/ (y + 4) = 3/4
From equation 1, y = 7x/5 = 1.4x so substituting in equation 2 :
(x + 4)/ (1.4x + 4) = 3/4
3(1.4x + 4) = 4(x + 4)
4.2x + 12 = 4x + 16
0.2x = 16 -12 = 4
x = 4/0.2 = 20 = George's age.
So y = 1.4x = 1.4 * 20 = 28 = Genemy's age.
Answer:
the answer is the last option, y > 2x-2
You just need to plot them on a graph and see how many spaces are in between each. So if you plot (1,9) remember it's X, Y axis. Start from zero on the graph. Since it's positive go over 1 to the right and up 9. Then do the same for the rest. Then count how many units are between each point on the graph and find the one that is 5 units apart.
