write the equation of the line using the given information. type your awnser in slope intercept form,y=mx+b
Answer:
y=3/-1x+4
Step-by-step explanation:
Okay so first thing you need to know is that if there is an ordered pair (x, y) where x is 0, your y-intercept is your y. For example, your problem has (0, 4) your x is 0 and your y is 4. Therefore your y-intercept is 4 which is the b. To find your mx, or slope, you need to do (y2-y1)/(x2-x1). Your y2 will be your y in your second ordered pair and your y1 will be in your y in the first ordered pair. Same for your x. So, (4-1)/(0-1) which equals 3/-1. 3/-1 is your slope. So, your answer in slop intercept form is: y= 3/-1x+4. You could also try y= -3x+4 if that makes you more comfortable.

George hiked from the top of a hill to the valley floor. The elevation at the top of the hill is 127 feet above sea level. The valley floor is 52 feet below sea level. George stopped at a rest stop that is at an elevation exactly halfway between the top of the hill and the valley floor. What is the elevation, in feet, of the rest stop? I need someone to also explain how they got the answer ;-;
Answer:
[tex]Halfway = 37.5[/tex] --- above the sea level
Step-by-step explanation:
Given
[tex]Top = 127ft[/tex] --- above sea level
[tex]Valley\ Floor = 52ft[/tex] --- below sea level
Required
Determine the elevation at half way
To do this, we simply add the elevations of the top of the hill and the valley floor.
Then calculate the average by dividing the sum by 2
[tex]Total = Top + Valley\ Floor[/tex]
[tex]Total = 127 + (-52)[/tex]
Note that the negative sign represents below sea level
[tex]Total = 127 -52[/tex]
[tex]Total = 75[/tex]
At half way, the elevation is:
[tex]Halfway = \frac{1}{2} * Total[/tex]
[tex]Halfway = \frac{1}{2} * 75[/tex]
[tex]Halfway = 37.5[/tex] --- above the sea level

A 47-foot tall tree casts a shadow that is 89 feet long find the measure of the angle elevation
Answer:
The angle is [tex]\theta =27.84^o[/tex]
Step-by-step explanation:
From the question we are told that
The height of the tree is [tex]h = 47 \ ft[/tex]
The length of the shadow is [tex]L = 89 \ ft[/tex]
Generally applying SOHCAHTOA , the angle of elevation is evaluated as
[tex]tan \theta = \frac{h}{L }[/tex]
=> [tex]tan \theta = \frac{47}{89}[/tex]
=> [tex]tan \theta = 0.52809[/tex]
=> [tex]\theta = tan^{-1} [0.52809 ][/tex]
=> [tex]\theta =27.84^o[/tex]

Answer:
y=1/2x+11
Step-by-step explanation:
use the slope of one half and the point and put them into point slope form.
y-y1 = m(x-x1) or y-16 = 1/2(x-10), distribute 1/2
y-16=1/2x - 5, add 16 to both sides
y = 1/2x + 11

Estimating Using Compatible Numbers
You purchase 3 items for $4.23. About how much did you spend?
9514 1404 393
Answer:
about $12
Step-by-step explanation:
For estimating purposes, you often want to round numbers to 1 or 2 significant digits. The price $4.23 can be rounded to $4. Then 3 such items will cost about ...
3×$4 = $12
You spent about $12.
_____
Additional comments
Along with an estimate, you often want to estimate the error in the estimate. Here, a first approximation of the error is that it is 3 × $0.20 too low. That is, the estimate of spending will be closer if we revise it upward by $0.60 to $12.60.
We know that even that estimate is low by $0.03 on each of the 3 items, so a better approximation of the spending is $12.60 +0.09 = $12.69.
This has accounted for all of the errors, so the actual spending was $12.69.
A) Complete the tables of value for x + y = 6
B) on the grid draw the graph of x + y = 6 for values of x between -2 to 3
9514 1404 393
Answer:
see attached
Step-by-step explanation:
You can make the work a little easier by solving the equation for y:
x + y = 6
y = 6 - x . . . . . . . subtract 6 from both sides
Now, you can fill in the x-values and find y quickly. For example, ...
y = 6 -(-2) = 8 . . . for x = -2
y = 6 - 3 = 3 . . . . for x = 3
These values are shown in the attached table and graph.

3. Kiran walked at a constant speed. He walked 1 mile in 15 minutes. Which of these equations represents the distance d (in miles) that Kiran walks in i minutes? Show your reasoning.
Answer:
C
Step-by-step explanation:
It is C because you get the equivalent from the t and that t is the number 1 so 15×1 is 15
The solution is Option D.
The equation is d = ( 1/15 ) t
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed of Kiran be represented as = s
Let the distance traveled by Kiran be = d
Let the time taken by Kiran to travel d distance be = t
Now , the value of d = 1 mile
The time taken by Kiran t = 15 minutes
So , the speed of Kiran s is given by the formula
Speed = Distance / Time
Substituting the values in the equation , we get
s = d/t
s = 1 / 15 miles / minute
So , the speed is 1/15 miles / minute
Now , the equation to represent the distance d Kiran walks in t minutes is given by
Distance d = Speed s x Time t
d = ( 1/15 ) t
Therefore , the value of d = ( 1/15 ) t
Hence , The equation is d = ( 1/15 ) t
