Find all real zeros of tf(x)=x-14x² + 47x-18​

Mathematics
1 answer:
BabaBlast [244]3 years ago
4 0

Answer:

x=3/7 and x= 3

Step-by-step explanation:

First simplify:

-14 x^2 +48x -18

divide everything by -2

-2(7 x^2 -24x +9) (Multiply the leading coefficient 7 by the constant 9)

-2 (x^2 -24x +63)

-2 [(x-3)(x-21)] Now divide the 7 that you multiplied earlier from 3 and 21

-2 [(x-3/7)(x-21/7)]

-2 [(7x-3)(x-3)]

Hence, the zeroes are 3/7 and 3

Hope this helps!

Answer:

3/5

Step-by-step explanation:

The formula is y = mx + b

m = slope

to get m, move add 3x to both sides and divide by 5.

-3x + 5y = 10

5y = 3x + 10

y = 3/5x + 2

So slope is 3/5

Find the solution to the following system of equations: <br><br>y+2x=3<br>y-4x=10​
Korolek [52]

Answer:

x=-7/6, y=16/3. (-7/6, 16/3).

Step-by-step explanation:

y+2x=3

y-4x=10

-----------

y=4x+10

4x+10+2x=3

6x+10=3

6x=3-10

6x=-7

x=-7/6

y+2(-7/6)=3

y-14/6=3

y=3+14/6

y=18/6+14/6

y=32/6=16/3
