Answer:
P'(-3, -8), Q'(-6, 4), R'(1, -1)
Step-by-step explanation:
When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign: it becomes (x, -y).
Thus, if a point P, say, (-3, 8) is eightn units above the x-axis, its reflection P' will be the same distance below, at (-3, -8).
Thus, we get the following transformations.
P (-3, 8) ⟶ P' (-3, -8)
Q (-6, -4) ⟶ Q' (-6, 4)
R (1, 1) ⟶ R' (1, -1)
Thus, the vertices of the reflected triangle are P' (-3, -8), Q' (-6, 4), R' (1, -1).
The image below shows ∆PQR and its reflection ∆P'Q'R' across the x-axis.
Answer:
Please find a representation of the factor rainbow below.
The missing factors are: 4, 24, and 144
Step-by-step explanation:
The factors of a number are those numbers that can divide another number without remainder. In this case where Katya factored 288, it means she listed the numbers that can divide 288 without reminder (factors of 288). However, among the factors she listed, THREE factors are missing.
To get the missing factors, we can use a FACTOR RAINBOW, which is a display of the factors of a number in a rainbow shape. The factors are arranged from smallest to largest number in such a way that the two numbers attached to a line can be multiplied to give the original number.
From the attached factor rainbow (see attached image), it can be observed that factors: 4, 24, and 144 are missing in the list of factors Katya provided.
