Answer:
40
Step-by-step explanation:
y = 4
z = 2
8y + 12 - 2z
8(4) + 12 - 2(2)
32 + 12 - 4
44 - 4
40
Reflection across the line y=x simply swaps the x and y coordinates.
K'(-2, -5), A'(1, -4), I'(-1, 0), J'(-4, -2)
45+10= 55
55+10= 65
65+1= 66
66+1= 67
67+1= 68
68+1= 69
69+1= 70
70+1= 71
Because 10+10+1+1+1+1+1+1= 26,
71 is your answer :)
Answer:
x = 2
Step-by-step explanation:
Since this is a 45-45-90 triangle, the 2 legs will be the same, meaning that y will also be
.
We can then solve for x using the Pythagorean theorem:

Or, we could use a quicker approach: if the triangle is a 45-45-90 triangle, the hypotenuse will be
times the length of 1 leg. It essentially does the same thing; it's just faster so you could save time on tests.
