Answer:

-1

Step-by-step explanation:

3+-4

Since the signs are opposite, we subtract the two numbers and take the sign of the larger

4-3 =1

The sign of the larger number (-4) is negative

-1

3+-4 = -1

For this case, what we must do is solve the following algebraic expression:

$3 + (-4)$

According to the law of signs we have to:

$+ * + = +\\+ * - = -\\- * - = +$

Thus, applying the aforementioned law we have to: $3 + (-4) = 3-4$

Rewriting we have:

$3 + (-4) = -1\\$

Answer:

$3 + (-4) = -1\\$

Tom and Jerry have a pool with a diameter of 12 ft. What is the<br> circumference of the pool?

RSB [31]

Hello!

Answer:

$\large\boxed{C = 12\pi ft\text{ or } C = 37.68ft}$

$\text{Formula for the circumference of a circle:}$

$C = d\pi$

$\text{In this instance, d = 12 ft. Plug this value into the equation:}$

$C = 12\pi ft \text{ or } C = 37.68 ft (\pi = 3.14)$

Solve 4b +8= 6b - 4 b= ?

AnnyKZ [126]

Answer:

B = 6

Step-by-step explanation:

1. 4b + 8 = 6b - 4

2. Add 4 to both sides: 4b + 12 = 6b

3. Subtract 4b from both sides: 12 = 2b

4. Divide 12 by 2: b = 6

To the nearest hundredth what is the value of X

disa [49]

<h2>Hello!</h2>

The answer is:

The value of "x" is 90.16

To solve the problem we need to use the trigonometric identity of the sine that establish that:

$Sin(\alpha )=\frac{OppositeSide}{Hypotenuse}$

So, we are given the following information:

$\alpha =48(degrees)\\\\OppositeSide=67$

Then, applying the trigonometric identity, we have:

$Sin(48)=\frac{67}{Hypotenuse}$

$Sin(48)=\frac{67}{Hypotenuse}\\\\Hypotenuse=\frac{67}{sin(48)}=90.157=90.16$

Hence, the value of "x" is (rounded to the nearest hundreth) 90.16.

Have a nice day!

Answer:

value of a is -19

value of b is 10

Step-by-step explanation:

<u>Given</u>

p(x) = 6x³ + ax² + 9x + b

Since it is given (x-2) & (2x-1) are the factors of given polynomial p(x) .

So, x = 2 & x = -1/2 are the solutions of given polynomial .

<u>when </u><u>x </u><u>=</u><u> </u><u>2</u><u> </u>

p(2) = 6(2)³ + a(2)² + 9 (2) + b = 0

p(2) = 6×8 + 4a + 18 + b = 0

p(2) = 48 + 4a + 18 + b = 0

p(2) = 66 + 4a + b = 0

4a + b = -66 -------(i)

Now ,

when x = -½

p(-½) = 6(-½)³ + a (-½)² + 9(-½) + b = 0

6 × (-⅛) + a/4 - 9/2 + b = 0

-3/4 + a/4 - 9/2 + b = 0

-3 + a -18+4b/4 = 0

-21 + a + 4b = 0

a + 4b = 21 -------(ii)

Now, multiplying the equation (ii) by 4 we get

4a + 16b = 84 -----(iii)

Substracting equation (i) from (iii) we obtain

15b = 150

b = 150/15

b = 10

Now, putting the value of b = 10 in equation (ii) we get

a + 40 = 21

a = 21-40

a = -19

So, the required value of a & b are 10 & -19 respectively .
