Step-by-step explanation:
Here, we want to seek why the system has no solutions
An example is necessary
Let us have two lines with equal slopes and different y-intercepts
y = 2x + 5
y = 2x - 3
To solve this system, we equate the y-values
2x + 5 = 2x - 3
The reason why this has no solution is that there is no x value that would validate the equality
It is impossible to find an x value which when inserted would make both equations equal
In the absence of this, we can make that conclusion that the system of equations has no solution
Brody and Carrie like to hike in the mountains. From the trailhead, they climb 103 feet until they reach a waterfall. On the next part of the trail, they descend 84 feet. To reach their destination, Brody and Carrie must then climb another 194 feet. Their destination is 734 feet above sea level. At what elevation is the trailhead?
Answer:
521 feet.
Step-by-step explanation:
In the given question, the number of feet covered with respect to climbing would have a positive value. While the number of feet descended would have negative value.
The total feet covered by Brody and Carrie, with the elevation of the trail-head should be equal to the elevation of their destination above sea level.
To determine the elevation of the trail-head, let its elevation be represented by h.
So that,
h + 103 - 84 + 194 = 734
h + 297 - 84 = 734
h + 213 = 734
h = 734 - 213
h = 521
h = 521 feet
The elevation of the tail-head is 521 feet.

what is a scale score of 1074 and a grade equivalent 6.8?
Answer:A grade equivalent (GE) score is described as both a growth score and a status score both. ... For example, if a seventh grade student earned a GE of 8.4 her raw score is like the raw score the typical student would likely earn on the same test at the end of the fourth month of the eighth grade.

Use the picture below of the isosceles triangle to solve for x & y.
a. x=47 y=43
b. x=90 y=43
c. x=90 y=86
d. x=86 y=43
Answer:
1) because A and B are supplementary
=> 2x + 4 + 3x + 16 = 180
<=> 5x = 160
<=> x = 32
with x = 32 => angle B = 3.32 + 16 = 96 + 16 = 112
2) see in the picture, because triangle ABC is the isosceles triangle => angle A = 180 - 2.47 = 180 - 94 = 86
we also have:
2y = 86
x = y + 47
=> y = 43
x = 43 + 47 = 90

A food cooperative is a business that usually offers special prices on locally grown food and produce. Some are clubs and some are retail stores. A club costs a one time club fee of $20 and a cost of $15 per week. A retail store costs no club fee and a cost of $17.50 per week. After how many weeks will the cost of the club and the retail be the same?
Answer:
The indifference point is 8 weeks.
Step-by-step explanation:
First, we establish the total cost formula for each:
x= number of weeks
Club:
Total cost= 20 + 15*x
Retail:
Total cost= 17.5*x
Now, we equal both formulas and isolate x:
20 + 15x = 17.5x
20 = 2.5x
8=x
The indifference point is 8 weeks.
Prove:
Total cost= 20 + 15*8= $140
Total cost= 17.5*8= $140

Wyatt buys a one-quart bottle of juice for $4.80. What is the unit rate of the cost of
the juice per fluid ounce?
Answer:
Unit rate per fluid ounce = $0.15
Step-by-step explanation:
Given that:
Cost of one quart bottle of juice = $4.80
We know that:
One quart = 32 ounces
Unit rate is the rate in which two quantities are compared and one of them is one.
Unit rate = [tex]\frac{4.80}{32}[/tex]
Unit rate = $0.15 per fluid ounce
Hence,
Unit rate per fluid ounce = $0.15
What are the coordinates of the point on the directed line segment from (-2, -5)(−2,−5) to (7, 10)(7,10) that partitions the segment into a ratio of 2 to 1?
Given:
The directed line segment from (-2, -5) to (7, 10).
A point partitions the segment into a ratio of 2 to 1.
To find:
The coordinates of that point.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of that point are
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
The point divides the line segment from (-2, -5) to (7, 10) in 2:1.
Using section formula, we get
[tex]Point=\left(\dfrac{2(7)+1(-2)}{2+1},\dfrac{2(10)+1(-5)}{2+1}\right)[/tex]
[tex]Point=\left(\dfrac{14-2}{3},\dfrac{20-5}{3}\right)[/tex]
[tex]Point=\left(\dfrac{12}{3},\dfrac{15}{3}\right)[/tex]
[tex]Point=\left(4,5\right)[/tex]
Therefore, the coordinates of the partition point are (4,5).

Determine if a triangle can be formed with the given lengths. If it can, classify it as acute,
obtuse or right.
5, 7, 10
Answer:
steps below
Step-by-step explanation:
1. It can be formed a triangle: sum of any two sides is greater than the 3rd side
2. It can't be an obtuse triangle: 5² + 7² = 74 < 10²
the triangle is an obtuse-angled triangle if the square of the longest side (c²) is greater than the sum of the square of other two sides (c²>a²+b²)

Step-by-step explanation:
We can tell if the graph is function or not by doing line test.
First, we draw a vertical line.
Second, if the graph intercepts the line more than two points then it won't be a function.
If the graph only intercepts the line only once (one point) then It is a function.
From the graph, It is a function.

If a factory can produce 410 sandwiches in 1 hour, how many sandwiches will it produce in 5 hours?
The answer is 2050 I believe
Every hour the factory makes 410 sandwiches so if we multiply this by 5 we should get our answer
410 x 1= 410
410 x 2= 820
410 x 3= 1230
410 x 4= 1640
410 x 5= 2050
how to draw angle of 135 degree
Answer:
So draw a straight line. This measures as 180 degrees on your protractor. Align your protractor to the straight line, with the circle point in the middle of the line and notice the labels on the side. One of them, between 90 and 180 on the outer scale will measure as 135. Mark this on top of the paper, and remove the protractor. When you remove it, extend your mark to the middle of your line, and this gives you an obtuse angle of 135 degrees. Be sure to recheck!
