When reaching mile marker 4 on the trail, Susan uses her GPS to find that her current elevation is 6135 feet. If she follows the trail until its end at mile marker 9, her elevation will be 8290 feet. What is the average change in elevation of Susan's position from mile marker 4 to mile marker 9, in feet per mile marker?

Answers

Answer 1

Answer:

Change in elevation= 431 feet/mile marker

Step-by-step explanation:

given data

Elevation at mile marker 4 = 6135 feet

Elevation at mile marker9 = 8290 feet

to find out

average change in elevation

solution

we get here average change in feet per mile marker  that is express as

average change in feet per mile = change in elevation ÷ change in mile marker     .....................1

put hree value we get

average change in feet per mile = [tex]\frac{8290-6135}{9-4}[/tex]  

average change in feet per mile = 431 feet/mile marker

so

Change in elevation= 431 feet/mile marker

You are saving to buy a new phone you have $150 in your bank account and can save $55 each week assuming you don’t spend any money write an expression to represent the amount of money you will have in your bank account after W weeks

Answers

Answer:

150+55w

Step-by-step explanation:

150+55w

150 never changes

(55)(w), 55 changes depending on number of weeks

Answer:

The expression is: 150 + 55W

Step-by-step explanation:

amount already in your a/c = $150

Amount saved per week = $55

Number of weeks to save for is W

Amount saved in W weeks is $55W

Total amount saved in W weeks is $150 + $55W

Ignoring the symbols, the expression is 150+55W

The midpoint of AB is M(-3,-3). If the coordinates of A are (-8,-2), what are the coordinates of B? Please explain

Answers

Step-by-step explanation:

Hey there!!!

Here,

The midpoint of AB is M(-3,-3) and coordinates of A is (-8,-2).

Now,

Using midpoint formulae,

[tex](x,y) =( \frac{x1 + x2}{2} ,\frac{y1 + y2}{2} )[/tex]

Put all values.

[tex]( - 3,- 3) = ( \frac{ - 8 + x}{2} , \frac{ - 2 + y}{2} )[/tex]

As they are equal, equating with their corresponding elements we get,

[tex] - 3 = \frac{ - 8 + x}{2} [/tex]

Simplify them.

[tex] - 6 = - 8 + x[/tex]

[tex]x = - 6 + 8[/tex]

Therefore, x= 2

Now,

[tex] - 3 = \frac{ - 2 + y}{2} [/tex]

Simplify them.

[tex] - 6 = - 2 + y[/tex]

[tex]y = - 6 + 2[/tex]

Therefore, y = -4.

Therefore, the coordinates of B are (2,-4).

Hope it helps...

g(x) = x - 1

GEOMETRY: need some help on these equations, i'm giving a lot of points for this.

Answers

Answer:

1) ML=93

2) GE=58

Step-by-step explanation:

1)

We want to find ML.

So, we need to find x first.

Note that the entire segment, NK, is the addition of the segments NM, ML, and LK. So:

[tex]NM+ML+LK=NK[/tex]

And we know their equations. So, substitute 110+4x for NM, x+103 for ML, 70 for LK, and x+243 for NK. Thus:

[tex](110+4x)+(x+103)+(70)=x+243[/tex]

On the left, combine like terms:

[tex](4x+x)+(110+103+70)=x+243[/tex]

Add:

[tex]5x+283=x+243[/tex]

Subtract 283 from both sides:

[tex]5x=x-40[/tex]

Subtract x from both sides:

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

Divide both sides by 4:

[tex]x=-10[/tex]

So, the value of x is -10.

Substitute this into ML to find it. So:

[tex]ML=(-10)+103[/tex]

Add:

[tex]ML=93[/tex]

And we're done!

2)

Here, we want to find GE. This means solving for x again.

Note that HF plus FE equates to the entire segment.

HG plus GE also equates to the entire segment.

Thus:

[tex]HF+FE=HG+GE[/tex]

Substitute 3x-129 for HF and 4 for FE.

Substitute 13x-993 for HG and 3x-185 for GE. Thus:

[tex](3x-129)+(4)=(13x-993)+(3x-185)[/tex]

Combine like terms on both sides:

[tex](3x)+(-129+4)=(13x+3x)+(-993-185)[/tex]

Add or subtract:

[tex]3x-125=16x-1178[/tex]

Add 1178 to both sides:

[tex]3x+1053=16x[/tex]

Subtract 3x from both sides:

[tex]1053=13x[/tex]

Divide both sides by 13:

[tex]x=81[/tex]

So, the value of x is 81.

To find out GE, GE is the 3x-185. So:

[tex]GE=3(81)-185[/tex]

Multiply:

[tex]GE=243-185[/tex]

Subtract:

[tex]GE=58[/tex]

And we're finished!

y=0,x=7

Solve for x:
X- 6 = -3x + 22

Answers

Answer:

Your answer is x=7

Step-by-step explanation:

[tex]x - 6 = -3x + 22[/tex] add 6 to both sides

[tex]x - 6(+6) = -3x + 22(+6)[/tex] cross out -6(+6) and add 22+6=28

[tex]x = -3x + 28[/tex] add 3x on both sides

[tex]x (+3x) = (+3x)-3x + 28[/tex]  x+3x=4x and cross out (+3x)-3x

[tex]4x = 28[/tex] divide 4 on both sides

[tex]\frac{4x}{4} = \frac{28}{4}[/tex] cross out 4 leave x and divide 28 and 4 =7

[tex]x=7[/tex]

Answers

Answer:

1) A point P is named or labeled by using a coordinate pair, where the regular notation is:

P = (x, y).

Where x and y are the horizontal and vertical components.

2) Three distinct points are collinear if exists a line that passes through the 3 points.

3) Three distinct points are complanar if they are not collinear, this means that:

We can have two colinear points (so one line connects them) and another point outside that line.

Then the set of 3 points is coplanar.
