Answer: $49
Step-by-step explanation: if there are 7 days in a week and he is saving for 7 weeks, its 7 x 7= 49
It is (6,11) just find the numbers that are in both sets.
27x²y - 43xy²
Factor of 27
1 x 27
3 x 9
Factor of 43
1 x 43
As you can see, there is no common number between 27 and 43, thus these numbers cannot be factored and must remain as is.
x and y are present in both terms, so we factor them.
xy(27x - 43y)
-4x+7=2y-3
Put this in y=mx+b
-4x+10=2y
Switch it around
2y=10-4x
Put it in y=mx+b
2y=-4x+10
Divide by 2
y=-2x+5
