Mathematics
1 answer:
raketka [301]3 years ago
7 0

Answer:

option 2

Step-by-step explanation:

Let equation for this table be y = mx + c, where m is the gradient (or slope) and c is the y intercept (or constant term)

m = (-4-(-2))/(7-5)

= -1

sub m = -1 and x = 1 and y = 2:

2 = -1(1) + c

c = 3

therefore, equation: y = -x + 3

Diego collected x kg of recycling. Lin collected 2/5 more than that. [ Select ] Lin biked x km. Diego biked 3/10 less than that.
Daniel [21]

I assume you want to mathematically represent the above

Answer and explanation:

If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:

Diego = x

Lin = x +2/5 of x= x+2/5x

if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:

Lin=x

Diego= x-3/10 of x= x-3/10x

If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:

Diego=x

Lin =4/7 of x = 4/7x

How can you use 4x7 to find 8x7?
max2010maxim [7]
4 x 7 is 28, and 8 x 7 is 56. You can use 4 x 7 to find 8 x 7 by multiplying that first and doubling that quotient.

Half of 56 is 28, therefore doubling that allows us to find the quotient of 8 x 7.
