Which scale factors produce a contraction under a dilation of the original image?

select each correct answer.

(a) -1.8

(b) -0.8

(c) 0.8

(d) 1.8

answer: (1,3) (3,-1) (5,-5) ?

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
