(−1.5, 0.25)
(−0.5, 0.75)
(1.5, 0.25)
(−2.5, 1.5)
Answer:
To approximate the solution to the system of equations, we need to find the point where the two lines intersect. From the second equation, we know that y = (1/2)x + 1. Substituting this expression for y into the first equation gives:
3x + 2[(1/2)x + 1] = -4
Simplifying and solving for x, we get:
3x + x + 2 = -4
4x = -6
x = -1.5
Substituting this value of x back into the second equation gives:
y = (1/2)(-1.5) + 1 = 0.25
Therefore, the solution to the system of equations is approximately (-1.5, 0.25).
So the answer is (−1.5, 0.25).
why does the equation y = 3x + 5 not represent a proportional relationship?
Answer:
Proportional relationship between two quantities x and y means that the quotient y/x stays constant, i.e. that there is a constant c such that y=cx. In our case we have that y=3x+5 which means that x and y are NOT proportional.
Answer:
Check the explanation provided
Step-by-step explanation:
This equation does not represent a proportional relationship because it's graph does not pass through the origin (i.e. 0,0)
[tex]y = mx + c[/tex]
where m = gradient OR slope
= 3
c = y-intercept
= 5
For the equation to have a proportional relationship, the value of c MUST BE '0’
If you spin the spinner 75 times, how many 2’s? (Note: Spinner has 5 spots ranging from 1-5)
If you spin the spinner 75 times, the expected number of 2's is 15.
About probabilitySince the spinner has 5 spots ranging from 1-5, the probability of getting a 2 on any given spin is 1/5.
Therefore, if you spin the spinner 75 times, the expected number of 2's is: (1/5) * 75 = 15
So, if you spin the spinner 75 times, you can expect to get 15 2's.
Probability itself has a number from 0 to 1.
The probability value is 0 (zero) for an event that is impossible or unlikely to occur, for example, cows laying eggs.
While the probability value of 1 (one) is an event that will definitely occur, such as the change between day and night.

Mr. Newton wants to buy a shirt in Leavenworth Kansas that cost $20.The sales tax in Leavenworth is 8%. What would be the total price of the shirt after adding the sales tax?
First find the amount the price increased.
amount of change
= (percent change) x (starting value)
= (8%) x ($20)
= (0.08) x ($20)
= $1.60
(Remember to convert the percent to a decimal before multiplying.)
Now add the tax onto the price:
$20 + $1.60 = $21.60
The price, including sales tax, is $21.60.

None of the statements of Chemistry reactions are necessarily true in all cases.
The reason is explained below:-
[reactants] < [products]: This statement is not necessarily true, as the amount of reactants and products in a reaction can vary. In some cases, the number of reactants is indeed less than the number of products, but in others, it may be equal or greater.[a] + [b] = [cd] [products] remain constant: The sum of the concentrations of reactants [a] and [b] may remain constant during a reaction, but the individual concentrations can change. The concentration of the products, represented by [cd], may also remain constant during a reaction, but the individual concentrations of the products can also change.

What is the perimeter of a regular dodecagon with a side length of 5√6 inches?
A. 50√6 inches
B. 60√6 inches
C. 60√30 inches
D. 360√2 inches
E. 55√6 inches
The perimeter of a regular decagon with sides 5√6 is 50√6 ( option A)
What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
The perimeter of a shape is obtained by adding all the sides together.
Therefore, if one side is 5√6 inches, a decagon which is of 10sides will have 5√6 inches at all it's sides because it is a regular polygon.
Therefore P= 5√6 × 10
P = 50√6 inches.
therefore the perimeter of the decagon is 50√6 inches

What is height of 165 cm?
The height of 165 cm is equivalent to 1.65 meters or 5 feet 5 inches.
This is a measurement of length or distance that is commonly used to describe the height of a person or object.
To convert centimeters to meters, you can simply divide the number of centimeters by 100. In this case, 165 cm divided by 100 gives you 1.65 meters.
To convert centimeters to feet and inches, you can first divide the number of centimeters by 2.54 to get the number of inches. Then, you can divide the number of inches by 12 to get the number of feet and the remainder will be the number of inches.
In this case, 165 cm divided by 2.54 gives you 64.96 inches. Dividing 64.96 inches by 12 gives you 5 feet with a remainder of 4.96 inches, which can be rounded to 5 inches.
So, the height of 165 cm is equivalent to 1.65 meters or 5 feet 5 inches.

what are the factor pairs needed to answer 3z^2 + 26z - 9
Answer:
daddy
Step-by-step explanation:
hey daddy
Answer:
Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).
Step-by-step explanation:
To factor the quadratic expression 3z^2 + 26z - 9, we need to find two numbers that multiply to give us 3 times -9 = -27, and add up to 26.
One way to do this is to list all the factor pairs of -27 and look for the pair that has a sum of 26:
-27 and 1
-9 and 3
-3 and 9
-1 and 27
We can see that the pair that adds up to 26 is -3 and 9. So we can use these numbers to write the quadratic expression as a product of two binomials:
3z^2 + 26z - 9 = (3z - 1)(z + 9)
Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

How would you make an equation of a linear function if it starts at 1127 and goes up 92 every hour
The solution is given below.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Consider that on a coordinate plane-xy, the x-values increase from left to right, and y-values increase from bottom to up.
Given that the linear graph passes through (1,1).
It is given that the graph goes 3 units up for every 2 units right. This can also be understood as the graph goes 3 units down for every 2 units left.
From the point (1,1), the x-value corresponding to 2 units left is given by,
x=1-2
x= -1
Similarly, from the point (1,1), the y-value corresponding to 3 units down is given by,
y = 1 - 3
y= -2
So the point (-1,-2) must also lie on the same linear graph.
Therefore, option (b) is the correct choice.

For two adjacent angles x° and (x + 30)° that make up a 90° angle, what is x
In the given situation, the required value of x for the given pair of adjacent angles is 30°.
What are adjacent angles?When two angles have a similar vertex and side, they are referred to as neighboring angles.
The vertex of an angle is the point at which the rays that make up its sides come to an end.
When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.
The definition of adjacent is next to or nearby.
Two next-door residences are an illustration of proximity.
Typically, we think of those who live on our street as neighbors.
So, we have:
x + x + 30 = 90
Now, solve for x as follows:
x + x + 30 = 90
2x + 30 = 90
2x = 90 - 30
2x = 60
x = 60/2
x = 30

. Write an equation of a line that does not have an x-intercept. The equation of a line is y= 3.6x + 2.
The equation of a line that does not have an x intercept is y = 3.
What is x intercept?x intercept of a line is the x coordinate of a point where the line touches the X axis. y coordinate of that point will be 0.
x intercept will be of the form (x, 0).
Every line will touch the X axis at any point.
The only line that will not touch X axis at any point will be the line parallel to the X axis.
Equation of a line parallel to the X axis is of the form y = k, where k is a constant.
Let k = 3.
So y = 3 has no x intercept.
Hence the line y = 3 does not have an x intercept.
