Answer:
-8.
Step-by-step explanation:
-2|-1+5|
The absolute value function |-1+5| = |4| = 4
-2 * 4 = -8.
You are right.
X=cost per hamburgurs
y=cost per hot dog
200x+150y=1450
200x+250y=1750
we can multiply first equation by -1 and add to 2nd
-200x-150y=-1450
<u>200x+250y=1750 +</u>
0x+100y=300
100y=300
divide both sides by 100
y=3
sub back
200x+150y=1450
200x+150(3)=1450
200x+450=1450
minus 450 both sides
200x=1000
divide both sides by 200
x=5
the cost of a hamburgur is $5
the cost of a hot dog is $3

Answer:
yes
Step-by-step explanation:
Trinomial means the equation consists of 3 terms therefore 2x+5y+7z is a trinomial.
Angle of fire in degrees: 90° + 30° = 120°
Angle of fire in radians: 180° = π
120° * π/180° = 120°π / 180° OR 4π/6 OR 2π/3
