If they are all in a line then we can find the equation of their line using: y = mx + b

First find m using points (2,5) and (3,3)

m = (5-3)/(2-3) = 2/-1 = -2

Now using (3,3) and m= -2 to solve for b:

3 = -2(3) + b
3 = -6 + b
9 = b

So our equation is y = -2x + 9
That is the solution for question b)

Now to find the mystery point, solve:

1 = -2x + 9
-8 = -2x
4 = x

So our mystery point is (4,1)

So for part a) the answer is k = 4

Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x A) -32/9 B) -9/32 C) 32/9 D) 9/32

Greeley [361]

Option C

$x = \frac{32}{9}$

Solution:

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

We have to solve for "x"

From given,

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

$x - 4 + \frac{x}{2} = x + 12 - 3x - x$

Combine the constants

$x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16$

Move the variables to left side of equation

$x + \frac{x}{2} + 3x = 16$

Combine the like terms

$2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}$

Thus option C is correct

Which problem would you use the following proportion to solve for? = what is 40% of 24? what percent is 24 of 40? twenty-four is

ser-zykov [4K]

First you have to remember that to find a percentage you can multiply a number by the percentage's decimal form, for example 40% of 100 would be .40 * 100.
Anyways, 24*.40 =9.6.
To find the percentage however, you must divide 24/40 which equals 0.6, which is equal to the percentage 60%.
To find the third question, you must multiply 24 by 2.5 (0.4 * 2.5 = 1) and you should get 60.
The last question you may have made a typo on, you repeated the first question.
