Triangle abc has coordinates of a(–8, –8), b(4, –2), and c(2, 2). find the coordinates of its image after a dilation centered at the origin with a scale factor of 1.5.
a) a(–5.33, –5.33), b(2.67, –1.33), c(1.33, 1.33)
b) a(–8, –8), b(4, –2), c(2, 2)
c) a(–12, –12), b(6, –3), c(3, 3)
d) a(–12, –8), b(6, –2), c(3, 2)

Option C -A(–12, –12), B(6, –3), C(3, 3)

Step-by-step explanation:

Given : Triangle ABC has coordinates of A(–8, –8), B(4, –2), and C(2, 2).

To find : The coordinates of its image after a dilation centered at the origin with a scale factor of 1.5.?

Solution :

A dilation centered at the origin with a scale factor of +k.

Coordinates became,

We have given k=1.5

And coordinates A(-8,8), B (4, -2), C (2,2)

Therefore, The new coordinates after dilation is A(–12, –12), B(6, –3), C(3, 3)

Hence, Option C is correct.

y=mx+b is the final answer!   : )

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
