Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up. What are
Galina-37 [17]

Answer:

B' = (-3,6)

Step-by-step explanation:

Given

A(4,5)

B(0,5)

C(3,-1)

<em>Translation: 3 units left and 1 unit right</em>

Required

Determine the new coordinates of B

Write out the coordinates of B

x = 0

y = 5

When a function is shifted to the left, we have to subtract the unit from the x value of the function;

<em>Shifting by 3 units left, the new x becomes </em>

<em />New\ x = 0 - 3<em />

<em />New\ x = -3<em />

<em />

When a function is shifted upward, we have to add the unit to the y value of the function;

<em>Shifting by 1 unit up, the new y becomes </em>

New\ y = 5 + 1

New\ y = 6

Hence, the new coordinates of B is

B' = (-3,6)

Use the spinner below to find the probability of getting the following number after 1 spin. P(multiple of 3) = (Round to 4 decim
Talja [164]

The value of the probability P(multiple of 3) is 0.3333

<h3>How to determine the probability?</h3>

The spinner that completes the question is added as an attachment

From the attached spinner, we have:

  • Total section = 12
  • Multiples of 3 = 4

The probability is then calculated as:

P(multiple of 3) = Multiples of 3/Total

This gives

P(multiple of 3) = 4/12

Evaluate

P(multiple of 3) = 0.3333

Hence, the value of the probability is 0.3333
