Find the slope of the line graphed below.
Given:
The graph of a line.
To find:
The slope of the graphed line.
Solution:
From the given graph it is clear that the line passes through the points (-2,2) and (2,5). So, the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{5-2}{2-(-2)}[/tex]
[tex]m=\dfrac{3}{2+2}[/tex]
[tex]m=\dfrac{3}{4}[/tex]
Therefore, the slope of the given graphed line is [tex]m=\dfrac{3}{4}[/tex].

Step-by-step explanation:
1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal
h, l and w are known; discover V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal
S, l and w are known; discover h, V and d
h = (S - 2lw)/(2l + 2w)
V = lwh
d = √(l2 + w2 + h2)
3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal
V, l and w are known; discover h, S and d
h = V/lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal
d, l and w are known; discover h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)

What is the speed of a car that traveled a
total of 300 kilometers north in 2 hours?
Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?
Answer:
With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:
C(x)=20+4x,where:
x is the number of rides
The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.
Find the value of x.

NO LINKS!! PLEASEE HELPP QUICK I POSTED THIS SO MANY TIMES AND NOBODY ANSWERS PLSSS HELP MEEE Write the slope-intercept inequality for the graph below. If necessary, use <=
fors or >= for >
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Slope- intercept form is y = mx + b, m being the slope and b being the y-intercept.
The slope is the rise of the line over the run. We can choose two points that are exactly on the line. Let's try points (-1, 0) and (0, -2). The line slopes down, so we already know the slope is negative. From point (-1, 0), the line goes down 2 units and over 1 unit. So, the slope is -[tex]\frac{2}{1}[/tex]. We can also simply say that the slope is -2.
The line intersects with the y-axis at point (0, -2), so the y-intercept is -2.
Because the shading is on the left side of the line and the line is solid, we can tell that y is less than or equal to -2x - 2. So, the equation is-
y ≤ -2x - 2
Express 130 and 325 as the sum of two squares in two different ways.
Answer:
3^2 + 11^2 = 130
7^2 + 9^2 = 130
---
1^2 + 18^2 = 325
6^2 + 17^2 = 325
Step-by-step explanation:
We want to express 130 and 325 as the sum of two squares in two different ways.
Then, we want to find two integers a and b such that:
a^2 + b^2 = 130
There is not an analytical way to do this, we just need to try with different integers.
Let's start with 130.
So we start by defining a as a really small integer, for example 1, and try to find b.
1^2 + b^2 = 130
b^2 = 130 - 1
b^2 = √129 = 11.3
This is not an integer, so let's try with another value of a.
a = 2
2^2 + b^2 = 130
4 + b^2 = 130
b^2 = 130 - 4
b = √126 = 11.2
This can be discarded again.
Now let's try with a = 3
3^2 + b^2 = 130
9 + b^2 = 130
b^2 = 130 - 9
b = √121 = 11
Nice.
So we can express 130 as:
3^2 + 11^2 = 130
Now let's find another pair.
In the same way, we can see that for a = 7 we get:
7^2 + b^2 = 130
42 + b^2 = 130
b^2 = 130 - 49
b = √81 = 9
Then we can write:
7^2 + 9^2 = 130
Now for 325:
With the same reasoning than before, we want to find two integers such that:
a^2 + b^2 = 325
Then we start evaluating a by the smallest values:
a = 1
1^2 + b^2 = 325
b^2 = 325 - 1 = 324
b = √324 = 18
Then we can write 325 as:
1^2 + 18^2 = 325
Now to find the next pair we need to keep testing values for a, we will get for a = 6:
6^2 + b^2 = 325
36 + b^2 = 325
b^2 = 325 - 36 = 289
b = √289 = 17
Then we can write:
6^2 + 17^2 = 325.

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
What is the value of x?
Answer:
x = 59
Step-by-step explanation:
combine all four angle measure expressions and set equal to 360°, then solve
x + x + 2x + 3 + 2x + 3 = 360
6x + 6 = 360
6x = 354
x = 59
Trent attaches his A+ test to the refrigerator with a circular magnet. Out of curiosity, he measures the magnet and calculates that it has a diameter of 4 centimeters. What is the magnet's area?
Answer:
12.6 cm²
Step-by-step explanation:
From the above question, the magnet is circular in shape
The area of a circle is given as:
= πr²
The area of the magnet = π × r²
Diameter = 4cm
r = Diameter/2 = 4cm/2 = 2cm
= π × (2cm)²
= 12.566370614cm²
Approximately = 12.6 cm²
The area of the magnet = 12.6cm²

6m - 8 = 1/2(-4m + 16)
Answer:
m=2
Step-by-step explanation:
6m - 8 = 1/2(-4m + 16)
Distribute
6m -8 = -2m +8
Add 2m to each side
6m-8+2m = -2m +8+2m
8m -8 = 8
Add 8 to each side
8m-8+8 = 8+8
8m = 16
Divide each side by 8
8m/8 = 16/8
m=2

Natalie is a salon owner. Yesterday, she did 3 haircuts and colored the hair of 1 client,
charging a total of $239. Today, she did 2 haircuts and colored the hair of 1 client, charging a
total of $192. How much does Natalie charge for her services?
Natalie charges $___
for a haircut and $__
for a coloring
Answer:
1 haircut = 47 dollars
1 colouring = 98 dollars
Step-by-step explanation:
Let [tex]x[/tex] be equal to the cost of 1 haircut.
Let [tex]y[/tex] be equal to the cost of 1 colouring treatment.
1) Form equations
Equation 1: 3 haircuts + 1 colour = 239 dollars
⇒ [tex]3x+y=239[/tex]
Equation 2: 2 haircuts + 1 colour = 192 dollars
⇒ [tex]2x+y=192[/tex]
2) Solve the system of equations
Subtract equation 2 from equation 1 to cancel out y (elimination)
- [tex]3x+y=239\\2x+y=192[/tex]
⇒ [tex]3x-2x+y-y=239-192\\x=47[/tex]
Therefore, Natalie charges 47 dollars for 1 haircut.
Plug x back into one of the equations to solve for y
[tex]2(47)+y=192\\94+y=192[/tex]
Subtract both sides by 94
[tex]94+y-94=192-94\\y=98[/tex]
Therefore, Natalie charges 98 dollars for 1 colouring treatment.
I hope this helps!

Answer:
2 = 4/2
Step-by-step explanation:
Well the one for the 2 wholes, Since 2 wholes equal 4/2
because 4/2 simplified is 2 whole it I believe would be 4/2
Answer:4/2,5/2
Step-by-step explanation:
I believe that 4,2 because it's going in order and 4/2= 2 which is shown below. And 5,2 because 5/2=2.5 which is half of 2 and 3.
