How would I factor this?14u^2 - 33u - 5 ​

Mathematics
1 answer:
Umnica [9.8K]3 years ago
6 0

Answer:

(7u+1)(2u-5)

Step-by-step explanation:

miltiply the coefficient of u² and the integer -5 = -70

from basic intuition: factors are -35 and +2

(which when added gives -33 and multiplies to give 70)

14u² -35u +2u -5

7u(2u-5) +1(2u-5)

(7u+1)(2u-5)

How do we write the approximate slope-intercept for of the equation using points (2,28) and (4,20)?
Butoxors [25]

Answer:

y = -4x + 36

Step-by-step explanation:

First, find the slope by calculation (y2-y1)/(x2-x1), you should get -8/2, or -4.

Next, plug the points into the equation y-y1 = slope(x-x1), getting y-28 = -4(x-2).

Simplify the equation and you get y =-4x + 36.

Hopefully this helps- let me know if you have any questions!
