Answer:

Step-by-step explanation:

We know that, two lines with same slope are parallel.

Thus two lines with same positive slopes are parallel.

The sum of 4 consecutive odd numbers is 40. What is the 2nd number in this sequence?
Mkey [24]
Try this option (it is not the only way):
1. if to use for consecutive odd numbers: n; n+2; n+4 and n+6), then it is possible to write their sum in equation: n+n+2+n+4+n+6=40.
2. if to solve this equation: n=7 it means that 7 - the 1st number of the given sequence.
Using n=7 the 2d number of this sequence is n+2=9.

answer: 9.

Write an equation in slope intercept form for the trend line shown below.
masha68 [24]

Step-by-step explanation:

Given line is passing through the points (3, 60) & (6, 50)

Therefore, slope of line:

m =  \frac{50 - 60}{6 - 3}  =   - \frac{10}{3}  \\ y - intercept \: (b) = 70 \\ equation \: of \: line \: in \: slope \: intercept \\ form \: is \: given \: as :  \\ y = mx + b \\   \huge \red{ \boxed{\therefore \: y =  -  \frac{10}{3} x + 70}} \\ which \: is \: the \: required \: equation.

margo can purchase tile at a store for $0.79 per tile and rent a tile saw for $24.At another store she can barrow the tile saw f
Flura [38]
T=number of  tiles bought
cost at store 1 is 0.79t+24
cost at store 2 is 1.19t

when will be equal cost?

0.79t+24=1.19t
minus 0.79t from both sides
24=0.4t
divide both sides by 0.4
60=t

answer is 60 tiles

Pls help me i just need help
Ray Of Light [21]

Step-by-step explanation:

the total cost is, of course, first the cost to buy the copier, and then the running costs per copy made.

it is really that easy.

the equations just put this into mathematical form :

A

y = 0.02×x + 800

B

y = 0.06×x + 600

please notice, we put $600 or $800 in as constant term, because these costs are the starting costs that we have, even if we never make a single copy (x = 0).

and then the total cost goes up with every copy we make.

I cannot draw here.

so, to find the number of copies where both copier systems would cost the same, means we have to say both equating deliver the same result :

0.02×x + 800 = 0.06×x + 600

200 = 0.04×x

x = 200 / 0.04 = 5000

when making 5000 copies both costs are the same.
