Answer:
No
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the inequality, evaluate and compare.
4(- 4) + 5(2) = - 16 + 10 = - 6 > - 7
Thus (- 4, 2 ) is not a solution
Answer:
10
Step-by-step explanation:
it is what it is
First simplify the equation.
3x+3y= -x+5y
4x=2y
2x=y
y=2x
Means that the y value is 2 times the x value.
answer: C but there are more solutions than just (1,2) and (2,4)
68.04 grams
Since it's half a pound you would need to find thirty percent of half a pound
500 at 40 each = £20000
To make a profit he needs to make more than £20000
20 broke so he sold 500-20 = 480 at 45 each.
480 x 45 = 21600
Profit = 21600 -20000 = 1600
His profit was £1,600
