Jerry started doing sit-ups every day. The first day he did 15 sit-ups then he had done the previous day. Today Jerry did 33 sit
Vikentia [17]
Y = sit ups, x= days

y= 2x + 15
33 = 2x + 15 (subtract 15 from both sides)
18 = 2x (divide both sides by 2)
9 = x, 9 days

The point C(2,3) is translated along a vector that is parallel to the line y=3x-2. The translation vector has magnitude square r
qaws [65]

Step-by-step explanation:

The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x

(parallel to y = 3x - 2, slope = 3).

We have x² + (3x)² = 10,

=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.

When x = 1, y = 3. When x = -1, y = -3.

Therefore 2 possible translation vectors

are (1, 3) or (-1, -3).

First new C' = (2 + (1), 3 + (3)) = (3, 6).

Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).

The possible images are (3, 6) and (1, 0).
