find the slope of each line
please help i am confused,
Answer:
Slope: 3
Step-by-step explanation:
There are two ways to solve this, one is more algebraically, and one is more logically.
Algebraically:
When only a graph is available to us as a resource, we can use a method called rise-over-run, which looks like this [tex]\frac{y}{x}[/tex].
Now, we select 2 points on the graph that are real integer values, meaning they aren't decimals. I will use (3,-2) and (4,1)
When we use rise-over-run we subtract the y-values and the x-values from each over before dividing. [tex]\frac{1-(2)}{4-3} = 3/1=3[/tex]
Logically:
We can use something called a "slope triangle" to find the slope. We will connect the same 2 points mentioned before.
We will draw a triangle to the right of the two points. I will attach a screenshot.

Answer:
y=3x+10 is the answer. I hope it is
3x + 5y = 7
How to solve it
Answer:
x=1 and y=4/5
Step-by-step explanation:
Given system of equations
3x+5y=7
5x+10y=13
Multiply first equation by 2
2(3x+5y)=2(7)
6x+10y=14
Eliminate y-variable to get "x"
6x+10y=14
- 5x+10y=13
x = 1
Substitute x=1 into either equation and find "y"
3x+5y=7
3(1)+5y=7
3+5y=7
5y=4
y=4/5
Therefore, x=1 and y=4/5
the system equations 2y=14-2x and y=-x+7
Answer:
Hey there!
When we are given what one of our variables is equal to, we can easily solve the system of equations via substitution, which is where we take the variable value, plug it into the other equation, and solve for the other variable.
In this case, we just take our value for y and plug it in for the value for y in the first equation and solve for x.
2(-x+7)=14-2x
-2x+14=14-2x
-2x=-2x
x=x
As we can see, there are infinitely many solutions to this first equation, which means that there is no possible way to solve for y because x has infinitely many solutions, so there are infinitely many solutions to this system of equations, because they are both the same line.

What is the volume of a right circular cylinder with a base diameter of 17. 5 ft and a height of 24. 5 ft? Enter your answer in the box. Use 3. 14 for pi and round only your final answer to the nearest hundredth.
Right circular cylinder has its height as the straight line connecting centers of its top and bottom circle. The volume of given cylinder is: 5889.95 cubic feet.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi \times r^2 \times h \: \rm unit^3[/tex]
For the given case, the considered right circular cylinder has these dimensions:
Its base diameter = 17.5 ft
Its height = 24.5 ft
Since radius is half of diameter, thus, radius of considered cylinder = 17.5/2 = 8.75 ft
Thus, using the formula for volume of right circular cylinder, we get:
[tex]V = \pi \times r^2 \times h \: \rm unit^3\\V \approx 3.14 \times (8.75)^2 \times (24.5) \approx 5889.95 \: \rm ft^3[/tex]
Hence, the volume of given cylinder is: 5889.95 cubic feet.

If the metal used to construct the spinner costs $13. 25 per square centimeter, how much will it cost to make this part of the compass? Round to the nearest cent. Cost = $.
Answer:
129.82
Step-by-step explanation:
I got the right answer
The cost to make the spinner is $132.50.
The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. The base of each of these triangles is 2 centimeters and the legs are 5 centimeters.
The area of each triangle is (1/2) * base * height = (1/2) * 2 * 5 = 5 square centimeters.
The total area of the spinner is 2 * 5 = 10 square centimeters.
The cost to make the spinner is 10 * $13.25 = $132.50.
Rounded to the nearest cent, the cost is $132.51.
Here is the calculation:
Area of each triangle = (1/2) * base * height = (1/2) * 2 * 5 = 5 square centimeters
Total area of the spinner = 2 * 5 = 10 square centimeters
Cost to make the spinner = 10 * $13.25 = $132.50
Rounded to the nearest cent, the cost is $132.51

Answer:
B) [tex]3\sqrt{3}[/tex]
Step-by-step explanation:
First simplify the radical on the right.
[tex]\sqrt{75}[/tex] is equal to [tex]\sqrt{25} *\sqrt{3}[/tex] , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know [tex]\sqrt{25}[/tex] is just equal to 25, which means the simplified version of [tex]\sqrt{75}[/tex] is [tex]5\sqrt{3}[/tex].
Then we can use this new representation to finish solving.
[tex]8\sqrt{3}-5\sqrt{3} =3\sqrt{3}[/tex], so the answer would be B

How do I solve this ?
Step-by-step explanation:
12 in long requires 96 pounds.
inversely proportional means that if I double the length of the handle, I need only half of the force.
so,
24 in long requires 48 pounds.
the product of both factors is constant for the system.
c = 12×96 = 1152 = 24×48 = ...
c is called "work". it is force times distance and usually expressed in joules.
(a)
so, the force is then work / distance.
force = 1152 / length
(b)
60 = 1152 / length
60 × length = 1152
length = 1152/60 = 288/15 = 96/5 = 19.2 in
the handle must be 19.2 in long to do the same work with 60 pounds of force (i.e. to loosen the bolt with 60 pounds of force).
A bouncy ball is dropped such that the height of
its first bounce is 4.75 feet and each successive
bounce is 75% of the previous bounce's height.
What would be the height of the 9th bounce of
the ball? Round to the nearest tenth (if
necessary).
The rate at which the ball drops from the height is an illustration of an geometric sequence
The height of the 9th bounce of the ball is 0.4 feet
How to determine the height of the ballThe given parameters are:
Initial height, a = 4.75
Rate, r = 75%
Bounce, n = 9
The function that represents the height of the ball is:
[tex]H = ar^{n[/tex]
So, we have:
[tex]H = 4.75 * (75\%)^{9[/tex]
Evaluate
[tex]H = 0.4[/tex] --- approximated
Hence, the height of the 9th bounce of the ball is 0.4 feet

Leonard went fishing and caught 40 fish in 8 hours. Charlotte went fishing and caught 32 fish in 8 hours. On average, how many fish did Leonard catch in one hour? On average, how many fish did Charlotte catch in one hour? Use unit rates to determine who caught fish faster.
To find the average divide total caught by total hours:
Leonard = 40 / 8 = 5 fish per hour
Charlotte = 32/8 = 4 fish per hour
Leonard caught more fish per hour.
Answer:
See Below.
Step-by-step explanation:
average: fishes caught/time takenFor Leonard: 40/8 = 5 fishes/hr
For Charlotte: 32/8 = 4 fishes/hr
On average, 5 fishes Leonard caught in one hour.On average, 4 fishes Charlotte caught in one hour.From this, we can identify that Leonard caught more fishes per hour or faster.

An investor bought 50 shares of stock for $98.40 per share when the value of the stock was $142.00 per share
The profit on the shares is $2180
How to determine the profit on the sharesFrom the question, we have the following parameters that can be used in our computation:
Number of shares = 50
Cost price = $98.40
Current price = $142.00
The profit on the shares is then calculated as
Profit = (Current price - Cost price) * Number of shares
Substitute the known values in the above equation, so, we have the following representation
Profit = (142 - 98.40) * 50
Evaluate
Profit = 2180
Hence, the profit is $2180
