You hike up a mountain path starting at 10 A.M. You camp overnight and then walk back down the same path at the same pace at 10 A.M. the next morning. Select the graph which best illustrates the relationship between distance from the top of the mountain and the time of day for both the hike up and the hike down.

Answer:

B. X > 8

Step-by-step explanation:

when dividing a negative denominator, you are flipping the sign. if the denominator doesn't have a negative sign, the sign isn't flipped.

steps:

subtract 30 by -18.

Soon you receive -48. Divide that by -6.

The signs soon flip giving you X> 8

Answer:

y=1/2x

Step-by-step explanation:

Its a positive slope so you go up 2 then right 4

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0,  0) and (x₂, y₂ ) = (6, 3) ← 2 points on the line

m = [tex]\frac{3-0}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

16

Step-by-step explanation:

If you start with 8 and the common ratio is 2, all you would do is 8*2 which is 16. Hope this helps!!

Answer:

D

Step-by-step explanation:

Answer:

D. i

Step-by-step explanation:

When putting i to a power, there is a rule.

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

And it repeats again, such as:

i⁵ = i

i⁶ = -1

And so forth.

This rule also applies to -i, but the values are slightly different:

(-i)¹ = -i

(-i)² = -1

(-i)³ = i

(-i)⁴ = 1

And that one keeps repeating such as

(-i)⁵ = -i

(-i)⁶ = -1

And so forth.

So to answer your question, (-i)³ = i.

Answer:

40

Step-by-step explanation: Make a proportional relationship. Make 25% into a fraction, 25/100. Then make 10 into a fraction using a variable. For example 10/p. Then cross multiply. 100x10=1000. Divide 1000 by 25 and the answer would be 40.

Answer:

Answer:

It depends

Step-by-step explanation:

It depends on how many problems are in the test. If the test has a standard amount of ten questions, you can only miss one question if you want to get a solid 90%. If the test has twenty questions, you can miss two to get that 90%.

If you're going for an 80% (or B), you can miss two on a ten-question test and four on a twenty-question test.

Again, it all depends on the number of questions and what percentage you want to get on the test.

Step-by-step explanation:

Change the equation to the general form [tex]Ax + By + C = 0[/tex].

[tex]y - 15 = - 6(x + 7) \\ y - 15 = - 6x - 42 \\ 6x + y - 15 + 42 = 0 \\ 6x + y + 27 = 0[/tex]

The slope

[tex] = - \frac{A}{B} [/tex]

[tex] = - \frac{6}{1} [/tex]

[tex] = - 6[/tex]

Answer:  Slope is -6

Step-by-step explanation:

We want to rearrange the equation to the form of y=mx+b, where m is the slope and b the y-intercept.

y−15=−6(x+7)

y−15=−6x-42

y=−6x-42+15

y = -6x - 27

The slope is -6

Answer:

h(-2) = 32

[tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex]

Step-by-step explanation:

Given the linear function, h(x) = -7x + 18:

In order to evaluate h(-2), simply substitute the value of the given input, x = -2, into the function.

h(x) = -7x + 18

h(-2) = -7(-2) + 18

h(-2) = 14 + 18

h(-2) = 32

Therefore, the output value when x = -2 is: h(-2) = 32.

This particular problem asks us to find the corresponding domain (x-value) given the range value of y = -2.  

Substitute the value of y = -2 into the function to solve for the value of x:

h(x) = -7x + 18

-2 = -7x + 18

Subtract 18 from both sides:

-2 - 18 = -7x + 18 - 18

-20 = -7x

Divide both sides by -7 to solve for x:

[tex]\displaystyle\mathsf{\frac{-20}{-7}\:=\:\frac{-7x}{-7} }[/tex]

[tex]\displaystyle\mathsf{x\:=\frac{20}{7}}[/tex]

Therefore, the value of x when h(x) = -2 is:   [tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex].

    by multiplying each term in the parentheses by the term outside

-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)

                   = -30y + 12u + 18

Answer:

m=0,-8

Step-by-step explanation:

Rearrange this Absolute Value Equation

|m+4|+7 = 11

Another term is moved / added to the right hand side.

|m+4| = 4  STEP 2:

Clear the Absolute Value Bars

The Absolute Value term is |m+4|

For the Negative case we'll use -(m+4)

For the Positive case we'll use (m+4)

STEP3:Solve the Negative Case

     -(m+4) = 4

Multiply

     -m-4 = 4

Rearrange and Add up

     -m = 8   Multiply both sides by (-1)

     m = -8

    Which is the solution for the Negative Case

STEP4:Solve the Positive Case

     (m+4) = 4

Rearrange and Add up

     m = 0

Which is the solution for the Positive Case

STEP5:

Wrap up the solution

m=-8

m=0

Answer:

He volunteered 10 hrs 15 min on average.

Step-by-step explanation:

The first week: 8 hrs

The second week: 12 hrs

The third week: 12 hrs

The fourth week: 9 hrs

8 + 12 + 12 + 9 = 41 hrs total

41 hours/4 weeks = 10.25 hrs (10 hrs 15 min)

Answer: 10.25 hours/week (On average, William volunteered 10.25 hours per week during these four weeks)

Step-by-step explanation:

To find an average, you need to add up each entity:

8+12+12+9=41

After that, you divide that number by n (the number of weeks)

41/4=10.25 hours

Answer:

b = -14

Step-by-step explanation:

Answer:

1st number: 37

2nd number: 22

Step-by-step explanation:

let n = 1st number

let n-15 = 2nd number

n+(n-15)=59

collect like terms: 2n-15=59

add 15 to both sides

2n=74

divide both sides by 2

n=37

n-15=22

Answer:

1/5

Step-by-step explanation:

it appears as those two distinct points on the graph are (-3,1) and (2,2)

so take the difference of the y-values and put it over the difference of the x-values to get a fraction to represent the slope

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

if you start from the point (-3,1) you must rise by one unit and then run five units to the right to get to (2,2)

Answer:

Do you mean 3/8 times 2/5? It equals 3/20

Step-by-step explanation:

So multiple the top numbers together for the top result and multiple bottom numbers for bottom result. 3 times 2 equal 6, 8 times 5 equal 40. the result is 6 over 40. After simplifying, we have 3 over 20 (dividing both 6 and 40 by 2)

Answer:

x = 6/5

Step-by-step explanation:

x-4        4x-9

------ = ----------

2             3

Using cross products

3 * (x-4) = 2 ( 4x-9)

Distribute

3x-12 = 8x-18

Subtract 3x from each side

3x-12-3x = 8x-18-3x

-12 = 5x-18

Add 18 to each side

-12+18 =5x-18+18

6 = 5x

Divide by 5

6/5 = 5x/5

6/5 =x
