9. 1/18

10. 1/18

Here is how I got my answer for 9:

Step 1: Simply $9/54$ to $1/6$ . Which leaves us with $1/6$ - $1/9$

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator. By multiplying $6*3$ and $9*2$ . Which leaves us with $3/18$ - $2/18$ .

Step 4: Subtract 3 and two, giving you your answer: $1/18$

Here is how I got my answer for 10:

Step 1: Simplify $6/12$ to $1/2$ . Which leaves us with $1/2$ - $4/9$

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator by multiplying $2*9$ and $9*2$ . Which leaves us with $9/18 - 8/18$ .

Step 4: Subtract 9 and 8, giving you your answer: $1/18$

Does (-15, -691) make the equation y = -51x - 74 true?

dimulka [17.4K]

Well, we can input both variables to check and see if the numbers hold.

-691 = -51(-15) - 74

-691 = 765-64

-691 = 701

(-15, -691) does not make the equation true.

2. Draw the image of ∆RST under the dilation with scale factor ⅓ and center of dilation at the origin. Label the image ∆R’S’T’.

Alchen [17]

Since center of dilation is the origin, this is easy. Just divide all of the x and y coordinate values by 3. Place the new point on the graph, and draw the triangle.

R' = R(3,6)/3 = (3/3,6/3)=(1,2). So R'(1,2)
S' = S(-3,6)/3 = (-3/3,6/3)=(-1,2). So S'(-1,2)
T' = T(-6,-6)/3 = (-6/3,-6/3)=(-2,-2). So T'(-2,-2)

So you now know the location of the 3 new points. R' at (1,2), S' at (-1,2) and T' at (-2,-2). Simply draw those 3 points on your graph and connect the lines to make a new triangle.
