What will the coordinates of Triangle RST be after it is translated 4units down and 3 units left
mote1985 [20]

Triangle RST has vertices:

R(-4,2)

S(3,5)

T(-4,-4)

Then, the triangle is moving to the left you subtract the number of units from the x coordinates of each vertex of the triangle.

And the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex. So:

For R'

(-4-3,2-4)=(-7,-2)

For S'

(3-3,5-4)=(0,1)

For T'

(-4-3,-4-4)=(-7,-8)

Answer:

\begin{gathered} R^{\prime}(-7,-2) \\ S^{\prime}(0,1) \\ T^{\prime}(-7,-8) \end{gathered}

Verizon [17]

Answer:

Mrs. Cabrini has a total of 2 1/8 quarts of tomato sauce.

Step-by-step explanation:

Since Mrs. Cabrini needs 2 quarts of tomato sauce to make a large batch of her spaghetti sauce. she has 1 1/4 quarts of her own, and she borrows 1/2 quart from the neighbor across the hall and 3/8 quart from the neighbor next door, to determine how many quarts does she have in all of her own must perform the following calculation:

1/4 = 0.25

1/2 = 0.5

3/8 = 0.375

0.25 + 0.5 + 0.375 = X

1.125 = X

1 + 1,125 = 2,125

Therefore, Mrs. Cabrini has a total of 2 1/8 quarts of tomato sauce.
