Which of the point-slope equations below are correct for the line that passes through points (-4,-14) and (1,3)?
Scrat [10]
(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5

y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one

y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one

Susan has 4 times as many quarters as dimes and 16 less dimes than nickels. If she has $13.45 in coins. How many of each coin do
Maslowich

Using a system of equations, it is found that Susan had 44 quarters, 11 dimes and 27 nickels.

--------------------------------

We are going to use:

  • x as the number of quarters.
  • y as the number of dimes.
  • z as the number of nickels.

A <em>quarter </em>is worth $0.25. A <em>dime </em>is worth $0.1, and a <em>nickel </em>is worth $0.05. Total of $13.45, then:

0.25x + 0.1y + 0.05z = 13.45

4 times as many <u>quarters as dimes</u>, thus:

x = 4y \rightarrow y = 0.25x

16 less <u>dimes than nickels</u>, thus:

z = y + 16 = 0.25x + 16

Replacing in the first equation, we find x:

0.25x + 0.1y + 0.05z = 13.45

0.25x + 0.1(0.25x) + 0.05(0.25x + 16) = 13.45

0.2875x = 12.65

x = \frac{12.65}{0.2875}

x = 44

Now, with x, we find y and z:

y = 0.25x = 0.25(44) = 11

z = y + 16 = 11 + 16 = 27

Susan had 44 quarters, 11 dimes and 27 nickels.
