First, to the author of this piece of instruction. A system of equations would give multiple curves which intersect, as depicted here by a pair of crossing lines. But presumably here the solution space is intended to be the green area. That makes this a system of inequalities, not of equations. Fix it please, you're confusing the children.
We check each point to see if it's in the green space.
a) (2,2) CHECK
b) (0,4) nope
c) (6,1) CHECK
d) (1,6) nope
e) (-2,8) nope
Answer is 3x because u do 12-9 which gets three and since it was originally 12x and you don’t know what X is you just put the x on the 3 and get 3x
Answer: If he earned $160 today the Han worked for 10 hours today
Step-by-step explanation:
112/7=$16= 1 hour of work
160/16=10 hours
Answer:
the answer is 176 hope this helps
Step-by-step explanation:
Answer:
Step-by-step explanation:
Any multiple of the given equation is also a dependent linear equation
From the equation
-5x+7y=2
Multiplying all through by any number, say 2
2(-5x)+2(7y)=2(2)
-10x+14y=4 is a dependent linear equation for -5x+7y=2
If you don't fancy using a multiple, you can write the gradient equation y=mx+c
-5x+7y=2
7y=5x+2
Dividing all through by 7 gives the equation as
y=5x/7 + 2/7
