Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-x+5y=-7
-3x +14y=-18
Answers
Answer:
One solution:(-8,-3)
Step-by-step explanation:
x = 5y + 7
Plug this in for variable x in equation [2]
[2] -3•(5y+7) + 14y = -18
[2] - y = 3
Solve equation [2] for the variable y
[2] y = - 3
By now we know this much :
x = 5y+7
y = -3
Use the y value to solve for x
x = 5(-3)+7 = -8
Solution :
{x,y} = {-8,-3}

What is the equation of this line?
A. y = 2x - 3
B. y = -1/2x - 3
C. y = -2x - 3
D. y = 1/2x - 3
Answers
Answer:
A. y = 2x - 3
Explaination:
It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.
Answer:
A
Step-by-step explanation:
X intercept : (3/2 , 0)
Y intercept : (0 , -3)

Kelly is using a compass and straightedge to perform the Geometric construction below.
Which of the following best describes the figure Kelly is constructing?
Answers
Answer:
The answer is A
Step-by-step explanation:
The line is perpendicular to RS through S
There are several constructions that can be done with the straightedge and the compass.
The statement that describes the figure Kelly is constructing is: (c) a line parallel to RS through Q
From the figure, we have the following observations
Two arcs intersect on line RSAnother set of two arcs intersect on the same level as point Q.When a line is drawn from point Q through the intersection of these lines, the line would be parallel to line RS.
Hence. we can conclude that:

B has a domain connected to many other ranges which makes a relationship but confuses the whole function making it incorrect.
For answer D, the x coordinates 1 and 3 both have two y coordinates. That again makes a relationship but confuses the function making that answer incorrect.

Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well?
Answers
Answer:
The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].
Step-by-step explanation:
The point-slope form of the equation of the line is represented by the following expression:
[tex]y - y_{o} = m\cdot (t-t_{o})[/tex] (1)
Where:
[tex]t[/tex] - Time, measured in seconds.
[tex]y[/tex] - Height below the top of the well, measured in feet.
[tex]t_{o}[/tex], [tex]y_{o}[/tex] - Known information of the well, measured in seconds and feet, respectively.
[tex]m[/tex] - Slope, measured in feet per second.
If we know that [tex](t_{o},y_{o}) = \left( 1\,s, -1\,ft\right)[/tex] and [tex]m = 4\,\frac{ft}{s}[/tex], then the equation in point-slope form of the line is:
[tex]y + 1 = 4\cdot (t-1)[/tex]
The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].

keith is an elevator operator in a big hotel. A(t)A(t)A, left parenthesis, t, right parenthesis models Keith's altitude (in meters relative to the ground) as a function of time (in minutes).Match each statement with the feature of the graph that most closely corresponds to it.
Answers
Answer:
Step-by-step explanation:
A relative maximum (or minimum) point is a point that is higher (or lower) than all of the points surrounding it.
This graph has a relative minimum point where A(t)=-12A(t)=−12A, left parenthesis, t, right parenthesis, equals, minus, 12, which means that Keith's lowest altitude was \textit{12}12start text, 12, end text meters below the ground.
A positive (or negative) interval is a domain interval over which the function values are all positive (or negative).
Since A(t)>0A(t)>0A, left parenthesis, t, right parenthesis, is greater than, 0 over the interval [6.5,10][6.5,10]open bracket, 6, point, 5, comma, 10, close bracket, this is a positive interval. This means that between the \textit{6.5}6.5start text, 6, point, 5, end text- and \textit{10}10start text, 10, end text-minute marks, Keith was above the ground.
An increasing (or decreasing) interval is a domain interval over which the function values increase (or decrease) as the input variable increases.

A telephone poll asked people whether they like playing golf. Of the 100 people polled,20 like playing golf. What percentage of the people like playing golf?
Answers
Given:
Of the 100 people polled, 20 like playing golf.
To find:
The percentage of the people who like playing golf.
Solution:
In the poll,
Total number people = 100
Who like playing golf = 20
Now, percentage of the people who like playing golf is
[tex]Required \%=\dfrac{\text{Number of people who like playing golf}}{\text{Total number people in poll}}\times 100[/tex]
[tex]Required \%=\dfrac{20}{100}\times 100[/tex]
[tex]Required \%=20[/tex]
Therefore, 20% of the people like playing golf.

A cake recipe calls for 1.5 cups of milk and 3 cups of flour. Seth made a mistake and used 5 cups of flour. How many cups of milk should he use to keep the proportions correct
Answers
Answer:
2.5cup of milkStep-by-step explanation:
Step one:
we are told that the ratio of milk to flour is 1.5cups to 3 cups
in other words, to prepare cake we need 1.5 cup of milk and 3 cups of flour
if we use 5 cups of flour we can balance up using the relation below
1.5cups of milk require 3 cups of flour
x cups of milk require 5 cups of flour
cross multiply we have
x=1.5*5/3
x=7.5/3
x=2.5cup of milk

Find the measure of angle 4
Answers
Answer:
i feel this is an incomplete picture
Step-by-step explanation:
Reasoning: The triangle on the left is an isosceles trainable. Meaning two of the angles are the same. That means that #1 is 62. A single triangle is equal to 180 degrees so 62+62=124 and 180-124=56 which means #2 is 56. Now, 2 & 3 are supplemental so added up they equal 180. So 180-56=124. #3 is 124 degrees. Now to figure out angle 4 all you have to do is add up 124+18=142 and take that from 180. 180-142=38. Angle #4 is 38 degrees.
