If a = -9 and b = -4, what is the value of ab?

Answer:

x=35°

3x= 105°

Step-by-step explanation:

[tex]40 + 3x + x = 180[/tex]

[tex]40 + 4x = 180[/tex]

[tex]4x = 180 - 40[/tex]

[tex]4x = 140[/tex]

[tex]x = \frac{140}{4} [/tex]

[tex]x = 35[/tex]

[tex]3x = 3(35) \\ 105[/tex]

B

Step-by-step explanation:

Take the three outaide the parentheses and distribute to both terms inside the parentheses. You would then get 3x+15= 15

subtract 15 from the left and right.

3x=0

Which means that x=0/3

So x=0

Answer:

50

Step-by-step explanation:

115 = p

115 = 2m + 15  

-15          -15

100 = 2m

/2      /2

50 = m

Binary, how to add numbers together.

     1101101

+       11011

10001000

This is just like adding regular numbers together.

For example, when you add 88 to 55, this is what will happen

   1(r)

  88

+ 55

13(+1)  3

143

With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.

The amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

For this case, we have:

Amount of aspirin in a person's body (in milligrams) after t hours of taking the medicine is:

[tex]a = 500\times(\dfrac{3}{4})^t[/tex] (in milligrams)

For t = 2 hours, we get:

[tex]a = 500\times(\dfrac{3}{4})^2 = 281.25 \: \rm milligrams[/tex]

Thus, the amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.

Answer:

116

Step-by-step explanation:

To find f(12), plug in 12 as x in the equation:

f(x) = 2/3x + 9x

f(12) = 2/3(12) + 9(12)

f(12) = 8 + 108

= 116

So, f(12) = 116

Answer:

Step-by-step explanation:

Answer:

4y + x = 8

Step-by-step explanation:

firstly, we choose any 2 points on the line

point 1 = (0,2)

point 2 = (4,1)

x1 = 0, x2 = 4

y1 = 2, y2 = 1

from,

[tex] \dfrac{y2 - y1}{x2 - x1} = \dfrac{y- y1}{x- x1} [/tex]

[tex] \dfrac{1 - 2}{4 - 0} = \dfrac{y- 2}{x- 0} [/tex]

[tex] \dfrac{ - 1}{4} = \dfrac{y- 2}{x- 0} [/tex]

Cross multiplying,

-1(x) = 4(y - 2)

-x = 4y - 8

4y + x = 8
