-4n+4n=0
First you would combine like terms
so if you add -4n and 4n together you get 0
and 0=0
so the answer is infintely many solutions
(T - 25) = M = J
T + M + J = 275
Plug in for M and J
T + (T - 25) + (T - 25) = 275
3T - 50 = 275
3T = 325
T = 108.33 (about)
Todd pays $108.33. Matt and Jeff pay $25 less than him.
108.33 - 25 = 88.33
Todd : $108.33
Matt : $88.33
Jeff : $88.33
Y<=2x+3
y=2x+3
x=0→y=2(0)+3=0+3→y=3→Point=(x,y)=(0,3)
y=0→0=2x+3→2x+3=0→2x+3-3=0-3→2x=-3→2x/2=-3/2→x=-1.5→
Point=(x,y)=(-1.5,0)
y<=2x+3 is the region below the right line passes trough the points (0,3) and (-1.5,0)
3x+y<=-2
3x+y-3x<=-2-3x
y<=-3x-2
y=-3x-2
x=0→y=-3(0)-2=0-2→y=-2→Point=(x,y)=(0,-2)
y=0→0=-3x-2→-3x-2=0→-3x-2+2=0+2→-3x=2→-3x/(-3)=2/(-3)→x=-2/3→
x=-0.67→Point=(x,y)=(-0.67,0)
y<=-3x-2 is the region below the right line passes trough the points (0,-2) and (-0.67,0)
Answer: First graph
Answer:
Step-by-step explanation:
Let us assume that the eagle's elevation is 100 meters above.
We can multiply -14.2 by 0.8.
We now get -11.36.
We can add this to (-14.2*4).
We now get -11.36 + -56.8.
We can add those together to get the answer.
-11.36 + -56.8 = -68.16.
Then we can add that to 100 (since it is negative).
100 + (-68.16) = 31.84.
The eagle's elevation would be 31.84 meters if its starting position was 100 meters, meaning that the equation would be (a - 68.16).
A) x=33.
180-28(given angle)=152
152 makes up the remaining angles
152=3x+(x+20)
substitute in options
x=33
