Ok. Length = L, Base = B
P = 2L + 2B
We know that B = 3L or L = B/3
so that's P = 2/3B + 2B = 2/3B + 6/3B = 8/3B
The domain and range of g are "all real numbers," so you want to find the range of f when its argument is from the set "all real numbers." That range is y > 0. The appropriate choice is
D. domain: all real numbers; range: y > 0
Answer:
x=0, y=-2
Step-by-step explanation:
Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:
-7x + 9y = -18
-(4x + 9y = -18)
__________
-11x = 0
x = 0
Since we know x=0, then we plug it back into one of the equations to get the value of y:
-7x + 9y = -18
-7(0) + 9y = -18
0 + 9y = -18
9y = -18
y = -2
Therefore, x=0, and y=-2
Answer:
12,39,21,18,24,17,12,25
Step-by-step explanation:
Answer:
-49
Step-by-step explanation:
you can first divide both sides by -6
so
-12 = y+37
so y = -12-37 = -49
