Explanation:

Start out by using the Distributive Property to convert from Point-Slope Form to Slope-Intercept Form:

y + 2 = −2x + 8

- 2 - 2

______________

$\displaystyle y = -2x + 6$

Now, starting from the y-intercept of [0, 6], you do $\displaystyle \frac{rise}{run}$ by either moving two blocks north over one block west or two blocks south over one block east [west and south are negatives].

I am joyous to assist you anytime.

The values of w is inversely proportional to m .if w=8 then m=25; what is m when w=20?

iren2701 [21]

Answer:

m = 10

Step-by-step explanation:

Given w is inversely proportional to m then the equation relating them is

w = $\frac{k}{m}$ ← k is the constant of variation

To find k use the condition w = 8, m = 25 , then

8 = $\frac{k}{25}$ ( multiply both sides by 25 )

200 = k

w = $\frac{200}{m}$ ← equation of variation

When w = 20 , then

20 = $\frac{200}{m}$ ( multiply both sides by m )

20m = 200 ( divide both sides by 20 )

m = 10

Drag the tiles to the correct boxes to complete the pairs.

Len [333]

Answer:

1. $(-2^2)^{-6}$ ÷ $(2^{-5})^{-4} \implies 2^{-32}$

2. $2^4 . (2^2)^{-2} \implies 1$

3. $(-2^{-4}).(2^2)^0 \implies -2^8$

4. $(2^2).(2^3)^{-3} \implies 2^{-5}$

Step-by-step explanation:

1. $(-2^2)^{-6}$ ÷ $(2^{-5})^{-4}$ :

$= \frac{ ( - 2 ^ 2 ) ^ { - 6 } } { ( 2 ^ { - 5 } ) ^ { - 4 } } = \frac{2^{-12}}{2^{20}} = 2^{-12-20}=2^{-32}$

2. $2 ^ 4 . ( 2 ^ 2 ) ^ { - 2 }$ :

$= 2^4 \times \frac{1}{2^4} = 1$

3. $(-2^{-4}).(2^2)^0$ :

$= (-2^4)^2 \times 1 = -2^8$

4. $(2^2).(2^3)^{-3}$ :

$= 2^4 \times \frac{1}{2^9} =\frac{1}{2^5} =2^{-5}$

I don’t really understand this?

Serga [27]

You replace the p in the given expression by -2 and the m by 3 and simplify

So its (-2)^ / 4 - 3

= 4/4 - 3

= 1 - 3 (note the division 4/4 is done first according to the order of operations rule)

Randolph is trying to find the equation of a line parallel to y = '1 over 4 x − 6 in slope-intercept form that passes through th

Aleksandr [31]

So remember that paralell lines have the same slope
y=1/4x-6
1/4=slope
so we set up a new equation in slope intercept form
y=mx+b
m=slope
b=y-intercept

y=1/4x+b

one solution si (-1,5) where x=-1 and y=5
subsitute
5=1/4(-1)+b
5=-1/4+b
add 1/4 to both sides
5+1/4=21/4=b

the answer is y=1/4x+21/4
