Answer: y = -3x + 10
Step-by-step explanation:
Using the formula for finding the equation of line ;
y - = m ( x -
)
= 4
= -2
m = -3
Substituting into the formula , we have
y - (-2) = - 3 ( x - 4 )
y + 2 = -3x + 12
writing the equation of the line in slope - intercept form , this means that we must make y the subject of the formula , that is
y = -3x + 12 - 2
y = -3x + 10
Answer:
28
Step-by-step explanation:
Number of coins in the bag ⇒ 84
Give that,
Dimes : Nickels : Pennies
3 : 2 : 1
You can see that, there are 6 parts . ( 3 + 2 + 1 = 6 )
And now let us write the types of coins in fractions.
Dimes ⇒
Nickels ⇒
Pennies ⇒
And now they're asking for the number of nickels.
To find that, you can multiply 84 ( number of coins) by it's fraction ( 2/6).
Let us solve.
84 ×
28
Therfore, there are 28 nickels.
