Please help me with this question and my next one!

Mathematics
1 answer:
Nookie1986 [14]3 years ago
6 0

Answer:

Step-by-step explanation:

If the price is linear, then the slope between each pair of points must be the same.

m = Δy/Δx

m = (150 - 70) / (5 - 1) = 20

m = (450 - 150) / (20 - 5) = 20

m = (1050 - 450) / (50 - 20) = 20

So the equation is indeed linear.  It has a slope of 20 and y-intercept of 50.

p = 20n + 50

23. not equivalent because the first row 3x-9y=5 then if you multiplied this equation by 2 it will be 2(3x-9y) = 2(5) so 6x-18y= 10 not 6x-9y=10


24.equivalent because the second row 2y-6x=8 multiplied by 2 is 2(2y-6x)= 2(8) so 4y-12x=16

25. equivalent because the first row 5x+3y=19 multiplied by 2 is 2(5x+3y) = 2(19) SO 10X+6Y=38 and the second row 2x+4y=20 multiplied by 5 is 5(2x+4y)= 5(20) so 10x+20y=100

Answer:

Well, the answer to 17 divided by 2635 is 155, however, the number in the box must be 850, I believe.

935 subtracted by 850 equals 85 divided by 17 equals 0.

I hope this was helpful!
