6. What is the slope of the line pictured?
Answer:
-1/3
Step-by-step explanation:
We can do this by counting the number of spaces away the points shown are. Starting from the leftmost point, you move down one, or -1, units, and right 3 units. Since slope is defined as rise over run, you can then say that the slope is:
-1/3

Distance from Washington to Springfield = 70.7 miles
Step-by-step explanation:
Two
If one side of a square is 50 miles, all sides are.
a^2 + b^2 = c^2
You are looking for c. a and b both equal 50
50^2 + 50^2 = c^2
c^2 = 2500 + 2500
c^2 = 5000
√c^2 = √5000
c = 70.7 miles
One
Again you are using a^2 + b^2 = c^2
c = 169
Perimeter of square 2 = 48
a = ?
a is square 3.b is square 2c is square 14s = 48
s = b = 48/4
s = b = 12
area_2 = s^2
Area_2 =12^2
Area_2 = 144
Area_ 1^2 - Area_2 ^2 = Area_3^2
169 - 144 = Area_3^2
side_3 = sqrt(25)
area= 25

Jonah is going to the hardware store for his Uncle Frederick. He needs to buy 4 yards of electrical wire and 14 quarts of liquid nails The store only sells wire by the foot. How many feet does Jonah need? (3 ft = 1 yd)
Answer:
Jonah needs 12 feet of electrical wire.
Step-by-step explanation:
[tex]\frac{3 feet}{1 yard}[/tex]= [tex]\frac{x}{4 yards}[/tex]
cross multiply
12 yard × ft = 1 yard x
12÷1=12
12 feet of wire.

The multiplication of the given equation i.e. [tex](5x + 4)^2[/tex] should be considered as the [tex]25x^2 + 40x + 16[/tex].
Calculation of the equation:Since the given equation is [tex](5x + 4)^2[/tex]
We have to break this equation
So, it can be like
[tex](5x)^2 + 2 \times 5x \times 4 + 4^2[/tex]
[tex]25x^2 + 40x + 16[/tex]
Hence, we can conclude that The multiplication of the given equation i.e. [tex](5x + 4)^2[/tex] should be considered as the [tex]25x^2 + 40x + 16[/tex].

9r - 66 = 116 - 4r
+4r +4r
13r - 66 = 116
+66 +66
13r = 182
divide both sides by 13

Stock prices for a certain company start at $12 per share an increase at a rate of
$2 per month. Write an equation of the function of the value of the stock price v,
as a function of the number of month that have passed, m.
Step-by-step explanation:
V = $12
M = The number of months
So, function = v + $2m
Lets take an Example = for example the stock price now is $20
V + $2m = $20
V = $12
So, 12 + $2m = 20
$2m = 20 - 12
$2m = 8
m = 8/2
m = 4
So this used we can easily find the number of months
Now let's try with the stock price only
The total now is $24
And 6 months passed
v + $2m = $24
v + $2(6) = $24
v + $12 = $24
v = $24 - $12
v = $12
So we got the same stock price
We found with this function the stock price as well as the number of months
