Mathematics
1 answer:
Basile [38]2 years ago
8 0

Answer:

The x and y intercept are (20,0)

Step-by-step explanation:

2x-4y=40—eqn1

-x+2y=-20—eqn2

Make x the subject of eqn2

-x=-20-2y

x=20+2y

plug this into eqn 1

2(20+2y)+4y=40

40+4y+4y=40

8y=40-40

y=0

plug y=0 into eqn2

-x+2(0)=-20

-x=-20

x=20

How many complex roots does the equation 0=2x3−4x2−x+1 have?
Anna11 [10]

Answer:

3 complex solutions/roots

Step-by-step explanation:

You find the complex solutions by combining the expressions and isolating the variable x. The roots are known as the x values when the graph intersects the x-axis; Therefore, replace <em>y </em>with 0 then solve for x.

x = -0.55138752

x = 0.42681725

x = 2.12457026

x ≥ -7 is everything greater than -7; x ≤ 4 is everything less than 4.

to include both, you'd click -7, drag right, and stop at 4

I need the answer to this question
malfutka [58]
Hi there friend:)


Your answer would be to add because 'gain" is the clue word to adding because it means adding on to something or means to have or get more of something added on, so when you add 5 + 0.25 you get 5.25, so 5 + 0.25 =
5.25


Sorry if its wrong

Have A Happy Thanks Giving With Family and Friends

Happy Holidays ^_^
