Answer:

Step-by-step explanation:

3x+y = 5

slope of line is -3

slope of any parallel to the line is also -3

point-slope equation for line of slope -3 that passes through (7,-1):

y+1 = -3(x-7)

You haven't provided the choices, but one of them is equivalent to the point-slope equation.

The value (in cents) of the change in a purse that contains twice as many nickels as pennies, five more dimes than nickels, and
nexus9112 [7]

Value of the pursue in cents: 131p+175

Step-by-step explanation:

Let's call:

p = number of pennies

The problem tells us that the pursue contains twice as many nickels as pennies, so the number of nickels is

n=2p

Also, the pursue contains five more dimes than nickels, so the number of dimes is

d=n+5=2p+5

And finally, the pursue contains as many quarters as dimes and nickels combained, so the number of quarters is

q=d+n=(2p+5)+2p=4p+5

The value of each type of coin is:

Penny: 1 cent

Nickel: 5 cents

Dime: 10 cents

Quarter: 25 cents

So, the total value of the pursue in cents is:

1p+5n+10d+25q

And substituting,

=p+5(2p)+10(2p+5)+25(4p+5)=\\p+10p+20p+50+100p+125=\\131p+175

So, this is the value of the change in the pursue in cents.

Triss [41]
Check the picture below

solve for "x"

since we know the two smallest sides for EFGH are 9 and 18, 9 is the smallest of all, and 18 is the next small

thus, for the the quadrilateral ABCD, the smallest is "x" and the next small is given, is 12, since that's smaller than 16 or 24
