Is this a true or false solution? y = 12x; (3,32)

Mathematics

Elenna [48]4 years ago

Substitute the x-value and see if you get the corresponding y-value. The corresponding y-value an x-value of 3 in this equation should be

y = 12(3)

y = 36

Since the coordinate (3,32) does not represent that, it is a false solution

Dimitri is helping to plan the school talent show. Each performer for the talent show has 666 minutes for his or her performance
strojnjashka [21]

We can find the answer by taking the total count of time, 150, and subtract 24 from it. This is because the 24 minute introduction is not part of the performances, so it is not part of our equation.  After we subtract the two numbers to get 126, we divide the remaining number by 6. This is because each performance lasts 6 minutes, so by dividing it from 126, we get the total amount of performances. The answer is 21.

Hope this helps!

When f(x) = (x - 1)³ + 6(px + 4)2 is divided by x + 2, the remainder is - 3. Find the values of p.​
dexar [7]

The value for p will be equal to 3 / 4.

We have the function as:

f(x) = (x - 1)³ + 6(p x + 4) 2

f(x) = x³ - 3 x² + 3 x - 1 + 12 p x + 48

f(x) = x³ - 3 x² + 3 x ( 1 + 4 p) + 47

Now, it is divided by x + 2 and leaves a remainder -3.

This means that if we will subtract 3 from f(x), it will be perfectly divisible by x + 2.

g(x) = x³ - 3 x² + 3 x ( 1 + 4 p) + 47 - 3

g(x) = x³ - 3 x² + 3 x ( 1 + 4 p) + 44

Now put x = -2:

(-2)³ - 3 (-2)² + 3 (-2) ( 1 + 4 p) + 44 = 0

-8 - 12 - 6 ( 1 + 4 p) + 44 = 0

- 20 - 6 - 24 p + 44 = 0

24 p = 18

p = 3 / 4.

Therefore, the value for p will be equal to 3 / 4.
