Which equation results from adding the equations in this system?
11x-3y=-17
-4x+3y=-18
A -7x= -35
B -7x= 35
C 7x= -35
D 7x= 35
adding 11x and -4x makes it 7x
adding-3y and 3y cancels it out so your left with nothing
adding a negative and a negative keeps it a negative so its 18+17 making it -35
so the answer is C
Which table represents a linear function?
Answer:
the second one
Step-by-step explanation:
The table that represents a linear function is the first one, where the values of y are obtained by multiplying the corresponding values of x by a constant factor of 5.
The first table:
x: 1,2,3,4,5
y: 5,20,45,80,125
In this table, the values of y are obtained by multiplying the corresponding values of x by a constant factor of 5.
The relationship between x and y is consistent and can be expressed by the equation y = 5x, which is a linear function.
The second table:
x: 1,2,3,4,5
y: 5,25,125,625,3125
In this table, the values of y are obtained by raising the corresponding values of x to increasing powers of 5.
The relationship between x and y is not consistent and cannot be expressed by a linear function.

Find the slope.
Answer:
-3
Step-by-step explanation:
The slope can be defined as the change in y over the change in x
we can break this down even more by doing the y of the second point minus the y of the first point over x of the second point minus the y of the first point
so [tex]\frac{2-8}{4-2}[/tex] = [tex]\frac{-6}{2}[/tex] = -3 so the slope is -3
we can check this by graphing it and we will see that we get y= -3x+14 for an equation that runs through all the points.
Daniel began filling an empty swimming pool at 8:30 a.M. After 5 hours, the pool contained 230 gallons of water. If the water input contained at a constant rate, how many more hours are needed to completely fill the 920-gallon pooo?
It will take 20 hours to fill the 920-gallon water in the pool if Daniel began filling an empty swimming pool at 8:30 a.M. After 5 hours, the pool contained 230 gallons of water.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
After 5 hours the pool filled with 230 gallons
Let's suppose that after x hours the pool will fill with 920 gallons
After x hours the pool filled with 920 gallons.
As the water input contained at a constant rate
So the value of x can be evaluated:
[tex]\rm x = \frac{920\times5}{230}[/tex]
x = 20 hours
Thus, it will take 20 hours to fill the 920-gallon water in the pool if Daniel began filling an empty swimming pool at 8:30 a.M. After 5 hours, the pool contained 230 gallons of water.

Greg needs to buy plastic forks. Brand A has a box of 25 forks for $1.97. Brand B has a box of 48 forks for $2.98
Find the unit price for each brand. Then state which brand is the better buy based on the unit price.
Round your answers to the nearest cent.
Answer:
To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.

For each graph below, state whether it represents a function.
Answer:
Graph 1, 2, 5, 6 are not functions.
Graph 3, 4 are functions
Step-by-step explanation:
For every input there can only be one output to be a function.
Of the given graphs, only graph[3] and graph[4] represent functions.
What is a function?
A function is a relation between a independent variable and a dependent variable such that the value of dependent variable depends upon the independent one. It is denoted by f(x).
Given are the graphs plotted for different expressions.
Now, for a given expression to be a function, it should have a single unique value of variable [y] in coordination with that of [x]. Of all the graphs given, only the continuous graph[3] and discrete graph[4] have unique or only one unique value of [y] for a value of [x]. So, only graph[3] and graph[4] represent functions.
Therefore, of the given graphs, only graph[3] and graph[4] represent functions.

How can a trend line be used to make a predictions?
Answer:
When a linear association is shown by a scatter plot, we can use a line to model the relationship between the variables. A trend line is a straight line that comes closest to the points on a scatter plot. We can use the trend line to make predictions.
Step-by-step explanation:
Answer:
A trend line can be used to make predictions because it shows the direction of interest. If the trend was how many people used yt in 2020, the trend line would be positive and it shows that more people are interested in yt. This would make the people who work at yt want to make it better, and people at other companies want to try and do something like yt, or something better.

Nina is selling three types of energy bars at a market stall. She bought 50 Enerbars at 30p per bar and 150 Grainbars at 50p per bar from her normal supplier. She was also given 50 Amazebars as a promotion from a new supplier. Nina sells the bars for £2.20 and manages to sell all the Enerbars and Grainbars but only some Amazebars. She makes a profit of £402.80. How many Amazebars did she sell?
Answer:
24
Step-by-step explanation:
Given that:
Cost of each Enerbar = 30p
Number of Enerbars = 50
Cost of each grain bar = 50p
Number of grain bars = 150
Number of Amazebars = 50
Cost of each Amazebar = 0p (Because it was given as promotion)
Sales price of each bar = £2.20
Total profit earned = £402.80
All other bars were sold but Amazebars.
To find:
How many Amazebars were sold?
Solution:
First of all, let us have a look at the profit earned by selling each type of bar.
Profit is nothing but the difference between sales price and cost price.
Profit at selling each Enerbar = £2.20 - 30p = £1.90
Profit at selling 50 Enerbars = £1.90 [tex]\times[/tex] 50 = £95
Profit at selling each grain bar = £2.20 - 50p = £1.70
Profit at selling 50 grain bars = £1.70 [tex]\times[/tex] 150 = £255
Profit by selling Enerbars and grain bars = £95 + £255 = £350
Profit by Amazebars = £402.80 - £350 = £52.8
Number of Amazebars sold = Profit by Amazebars divided by Profit by selling one Amazebar
[tex]\Rightarrow \dfrac{\£52.80}{\£2.2}\\\Rightarrow \bold{24}[/tex]

A line passes through the points (6, 8) and (5,5). What is its equation in slope-intercept
form?
Answer:
y = 3x -10
Step-by-step explanation:
Use the method [tex]\frac{rise}{run}[/tex].
I took a screenshot of the graph below, as an example of the rise over run method.
3 ÷ 1 = 3
To find the y intercept, count down on the graph until you reach the point where the line crosses.
In this case, the line crossed at -10 on the y-axis.
(Look at the second image)
So plug the numbers into the equation, and then you get y = 3x -10.

An atom of a certain element has 37 protons, 37 electrons, and a mass number of 85. How many neutrons are
in this atom?
Answer:
There will be 48 neutrons.
Step-by-step explanation:
Hope this helps and have a great day :)
There will be 48 neutrons in this atom.
What is mass number?The mass number of an element is the number obtained when the number of protons and neutrons in the nucleus of an atom of the element are summed together.
The addition of protons and neutrons in the nucleus of an atom is collectively known as the nucleon. Thus, the mass number of an atom can also be referred to as the nucleon of the atom.
This can be mathematically expressed as follows;
Mass number = number of protons + number of neutrons.
We are given that atom of a certain element has 37 protons, 37 electrons, and a mass number of 85.
So,
Mass number = number of protons + number of neutrons.
85 = 37 + n
n = 85 - 37
n = 48
