−24 − (18 ÷ 6) × (−12)

Answers

Answer 1

Answer:

Answer:

The expression is equal to 12.

Step-by-step explanation:

$-24-(18 / 6)*(-12)$

First of all, compute the parenthesis.

18 / 6 = 3

Now, replace 18/6 with 3 in our expression.

$-24-(18 / 6)*(-12)$

$-24-(3)*(-12)$

Next, compute the multiplication.

-12 * 3 = -36

Again, we'll replace that multiplication with negative 36:

$-24-(3)*(-12)$

$-24-(-36)$

Since subtracting a negative number is the same as adding a positive number:

$-24-(-36) = -24+36$

Compute the addition:

$-24+36=12$

$-24-(18 / 6)*(-12) = 12$

Answer: The expression is equal to 12.

What is 1/8 times something that gives you to 16/8

Answers

1/8 multiplied by 2 will give you 16/8

Simplify
(1/81) to the 1/4 power

Answers

${ \left( \frac { 1 }{ 81 } \right) }^{ \frac { 1 }{ 4 } }\n \n =\sqrt [ 4 ]{ \frac { 1 }{ 81 } } \n \n =\frac { 1 }{ 3 }$

This is because...

$\frac { 1 }{ 3 } * \frac { 1 }{ 3 } * \frac { 1 }{ 3 } * \frac { 1 }{ 3 } =\frac { 1 }{ 81 }$

Which expression is equivalent to i to the power of 233a. 1
b.-1
c.i
d.-i

Answers

i works in a cycle of fours
i^0=1
i^1= i
i^2= -1
i^3=-i
So divide the number by four and whatever the remainder is you use in this key so 233/4 = 58 remainder 1 so that is equivalent to i^1 which is i
So the answer is c) i

A line passes through the point (-3,-4) and its y-intercept is (0,9). what is the equation of the line that is parallel to the first line and passes through the point (3,-7)?a. y=3/5x+2
b. y=5/3x+2
c. y=-5/3x-2
d. y=5/3x-2

Answers

You have a mistake in your question... y-intercept must be ( 0, -9 ), because with coordinates ( 0, 9 ) there is no answer.
The line equation of the 1st line:
-4 = -3m - 9
3 m = - 9 + 4
3 m = -5
m = - 5/3
If the 2nd line is parallel to this one m-value is also -5/3.
-7 = - 5/3 · 3 + b
- 7 = - 5 + b
b = - 2
Answer: C ) y = - 5/3 x - 2
