ANSWER 1

Consider the given equation,

3x−2y=5

put x=0 then,

3×0−2y=5

y=−25

Now, put y=0 then,

3x−2×0=5

x=35

Hence, (0,−25) and (35,0) is the answer.

ANSWER

As can be seen, the line for y=2x+3 extends up to infinity all over the number line.

For x=0,y=3, For x=1,y=5, For x=2,y=7

∴ For every value of x we get the different value of y

Hence it will have infinitely many solutions.

In the diagram, line segment CD is the perpendicular bisector of line segment AB, and E is a point not on either line that is on

Lelu [443]

Answer:

E would be closer to A

explanation:

if they were the same distance from both A and E it would be a point on the line CD, and if it was closer to E it would be on the other side of line CD.

i hope this is right :/

Your joke is so bad I would have preferred the joke went over my head and you gave up re-telling me the joke. To be honest this is a horrid attempt at trying to get a laugh out of me. Not a chuckle, not a hehe, not even a subtle burst of air out of my esophagus. Science says before you laugh your brain preps your face muscles but I didn't even feel the slightest twitch. 0/10 this joke is so bad I cannot believe anyone legally allowed you to be creative at all. The amount of brain power you must have put into that joke has the potential to power every house on Earth. Get a personality and learn how to make jokes, read a book. I'm not saying this to be funny I genuinely mean it on how this is just bottom barrel embarrassment at comedy. You've single handedly killed humor and every comedic act on the planet. I'm so disappointed that society has failed as a whole in being able to teach you how to be funny. Honestly if I put in all my power and time to try and make

ASHA 777 [7]

90,000 becuase 63,824 is rounded down to 60,000 and 29,452 is rounded up to 30,000. 60,000+30,000 is 90,000

The Expression 4x^2-p(x)+7 leaves a remainder of -2 when divided by (x-3) find the value of p

Romashka-Z-Leto [24]

Answer:

(c) For p = 15, $4x^2-p(x)+7$ leaves a remainder of -2 when divided by (x-3).

Step-by-step explanation:

Here, The dividend expression is $4x^2-p(x)+7$ = E(x)

The Divisor = (x-3)

Remainder = -2

Now, by REMAINDER THEOREM:

Dividend = (Divisor x Quotient) + Remainder

If ( x -3 ) divides the given polynomial with a remainder -2.

⇒ x = 3 is a solution of given polynomial E(x) - (-2) =

$E(x) - (-2) = 4x^2-p(x)+7 -(-2) = 4x^2-p(x)+9$ = S(x)

Now, S(3) = 0

⇒ $4x^2-p(x)+9 = 4(3)^2 - p(3) + 9 = 0\\\implies 36 - 3p + 9 = 0\\\implies 45= 3p , \\or p =15$

or, p =1 5

Hence, for p = 15, $4x^2-p(x)+7$ leaves a remainder of -2 when divided by (x-3).
