They could be 30 because 30x4 is 120
Answer:
P(x) = (x - 1)(x + 2)(x - 3)(3x + 1)
Step-by-step explanation:
Since P(1) = 0 and P(- 2) = 0, then
(x - 1) and (x + 2) are factors of P(x)
(x - 1)(x + 2) = x² + x - 2 ← is also a factor of P(x)
dividing 3 - 5x³ - 17x² + 13x + 6 by x² + x - 2 gives
P(x) = (x - 1)(x + 2)(3x² - 8x - 3) = (x - 1)(x + 2)(x - 3)(3x + 1)
Answer:
Scale factor of 1.6.
Step-by-step explanation:
The triangle is dilated and the images is an enlargement of the pre-image. This means all angles of the triangles are congruent and these form similar triangles. Because they are similar triangles which have been dilated, they have a common ratio known as the scale factor between their side lengths. The scale factor here is 1.6 and can be found by using the ratio 0.8/0.5 = 1.6.

Answer: y = 5x + 7</h3>
Work Shown:
y - y1 = m(x - x1)
y - (-3) = 5(x - (-2))
y + 3 = 5(x + 2)
y + 3 = 5x + 10
y = 5x + 10 - 3
y = 5x + 7
The equation is now in slope intercept form y = mx+b with m = 5 as the slope and b = 7 as the y intercept. Plugging x = -2 into this equation will lead to y = -3.
Side note: parallel lines have equal slopes but different y intercepts.
