We can conclude the following answers -
Kaden's graph has infinitely many solutions.Solution set for the given system of equations is (4, -3).What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is that on a coordinate plane, a line goes through (0, negative 1) and (2, negative 2). This line represents Kaden’s Graph. Also a system of equations is given as -
x + 2y = - 2
y = (x/2) - 5
{ 1 } -
Kaden's graph passes through the points -
(0, - 1)
(2, - 2)
We can write the equation of the Kaden's graph as -
y = {(- 2 + 1)/(2 - 0)}x + {- 1}
y = - x/2 - 1
There is only one equation for Kaden's graph. Hence, it has infinitely many solutions.
{ 2 } -
x + 2y = - 2
y = (x/2) - 5
We can write -
x = - 2 - 2y
So -
y = (- 2 - 2y)/2 - 5
y = - 1 - y - 5
2y = - 6
{y} = -3
x = - 2 - 2 x - 3
{x} = 4
Therefore, we can conclude that -

Can someone PLEASE explain in simple terms which trigonometric ratio to use, like tangent, cosine, or sine, and WHY?
Answer:
Use law of Cosines or Tangent
Step-by-step explanation:
This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.
However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:
c=a^2+b^2﹣2abcos(angle number). But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2
The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.

Mrs.E bought 3 drinks and 5 sandwiches for $25.05 and Mr.E bought 4 drinks and 2 sandwiches for $13.80. How much does each drink cost?
Answer:
$1.35
Step-by-step explanation:
Set up a system of equations, where d represents the price of one drink and s represents the price of one sandwich:
3d + 5s = 25.05
4d + 2s = 13.80
We can solve this by elimination by multiplying the top equation by -2 and multiplying the bottom equation by 5.
-6d - 10s = -50.1
20d + 10s = 69
Add them together:
14d = 18.9
d = 1.35

Answer:
Cheapest price is £25.38
Step-by-step explanation:
To determine the cheapest price that Sue can get the 10 rolls of wallpaper, calculate the cost of getting 10 rolls at each given price offer
=>Cost of getting 10 rolls at £9.21 per roll:
10 × £9.21 = £92.1
=>Cost of getting 10 rolls at £25.38 per pack of 3 rolls
£25.38 = 3 rolls
x = 10 rolls
x = (25.38*10)/3 = 253.8/3
10 rolls would cost x = £84.6
=>Cost of getting 10 rolls at £42.85 per pack of 5 rolls:
£42.85 = 5 rolls
x = 10 rolls
x = (10*42.85)/5 = 428.5/5
x = £85.7
From our calculation, getting 10 rolls at the price offer of £25.38 per pack of 3 rolls is the cheapest.
Therefore, the cheapest price is £25.38

A cone with radius 2 units is shown below. Its volume is 29 cubic units.
h
Find the height of the cone.
Use 3.14 form and round your ina answer to the nearest hundredth.
Answer:
[tex]h=6.93units[/tex]
Step-by-step explanation:
1. Use the formula of volume of a cone
Volume of a cone=[tex]\frac{1}{3}\pi r^{2} h[/tex]
2. Collecting the information from a question.
In the question, we know that radius=2 units, Volume of a cone=29 cubic units, height of a cone=?
In this question, we can also know that the question requires us to find the height of a cone.
3. Put the value of variables into the formula.
We can put all the information that are provided by a question into the formula of volume of a cone to find the answer.
[tex]\frac{1}{3} *3.14 * 2^{2} h=29 units^{3}[/tex]
pi replaces with 3.14, radius replaces with 2 units, Volume of a cone replaces with 29 units3 and we don't know what is the value of h.
Now, let's simplify and calculate the value of h.
We can simplify the formula like this,
[tex]\frac{314}{75}h =29 units^{3}[/tex]
[tex]\frac{314}{75}[/tex] is the result of [tex]\frac{1}{3}* 3.14*2^{2}[/tex]
Move [tex]\frac{314}{75}[/tex] to other side.
[tex]h=\frac{29units^{3} }{\frac{314}{75} }[/tex]
[tex]h= 6.92675 units[/tex]
But wait, this is not final answer yet, the question requires the answer to the nearest hundredth. So, we need to convert the answer to the nearest hundredth.
[tex]h= 6.92675 units[/tex]
[tex]h=6.93units[/tex]
So, the final answer is 6.93 units.
I hope my solution and explanation are clear for you. If you still cannot understand my point, you can ask me anytime!! Thank you!

Graph the relation shown in the table. Is the relation a function? Why or why not? {(-1, 9), (0, -1), (-1, 4), (4, 9)}
Answer:
Not a function
Step-by-step explanation:
For an equation to be a function, there should be only one y-coordinate per x-coordinate. Since this relation has both (-1,9) and (-1,4), this is not a function.
Answer:not a function
Step-by-step explanation:
because when you put the points on the coordinate plane your shape will come out as a v shaped object. In mathematics, a function is a binary relation over two sets that associates to every element of the first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers
