olga55 [171]

Answer: scale factor = 1.5

Step-by-step explanation:

$\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Side length of original figure}}$

Given: Triangle ABC is a scaled copy of triangle DEF.

Side AB = 12 cm and is the longest side of ABC.

Side DE = 8 cm and is the longest side of DEF.

$\text{For similar triangles, Corresponding sides are proportional.}$

AB is corresponds DE (longest side of both triangles)

So, $\text{Scale factor}=\dfrac{\text{AB}}{\text{DE}}=\dfrac{12}{8}=1.5$

Hence, the scale factor = 1.5.

QUESTION 4

vesna_86 [32]

Answer:

$f(3) =-8$

Step-by-step explanation:

Given

$f(x) = 2x + 5; x$

$f(x) =-3x + 1; x >1$

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

$f(x) =-3x + 1$

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

$f(3) =-3*3 + 1$

$f(3) =-9 + 1$

$f(3) =-8$
