to get the equation of any straight line, we simply need two points off of it, let's notice the picture above, the line passes through the origin and (8 , -5), so let's use those two points then
[tex]\stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{8}-\underset{x_1}{0}}} \implies \cfrac{ -5 }{ 8 } \implies - \cfrac{5 }{ 8 }[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{- \cfrac{5 }{ 8 }}(x-\stackrel{x_1}{0})\implies {\Large \begin{array}{llll} y=-\cfrac{5}{8}x \end{array}}[/tex]
Suppose a hurricane traveled 130 miles from point in the Atlantic Ocean to Florida coastline in 6 1/2 hours. How many miles per hour did the hurricane travel?
Answer:
The hurricane traveled 260 miles per hour.
Step-by-step explanation:
Given,
Distance covered by hurricane = 130 miles
Then time = [tex]\frac{6}{12}[/tex] hours=[tex]0.5[/tex] hour
Distance=Speed*Time
Speed=[tex]\frac{Distance}{Time}[/tex]
Speed=[tex]\frac{130}{0.5}[/tex]
Speed=260 miles per hour
So, the hurricane traveled 260 miles per hour

Write the math sentence as an equation: Negative eight times the sum of a number and 14.6 is 31.2.
−8r + 14.6 = 31.2
−8(r + 14.6) = 31.2
−8(r − 14.6) = 31.2
−8r − 14.6 = 31.2

The equation for the math sentence "Negative eight times the sum of a number and 14.6 is 31.2." will be; -8(r+14.6)=31.2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that math sentence as an equation:
"Negative eight times the sum of a number and 14.6 is 31.2."
Here,
-8 times (a number (sum=addition) and 14.6) = (equal to) 31.2
Therefore, the equation will be as;
-8(r+14.6)=31.2

10% = 0.1
A: 26(40)
B: 0.1x
when Option A = Option B
26(40) = 0.1x
1,040 = 0.1x
divided by 0.1:
1,040/0.1 = 0.1x/0.1
x = $10,400

A regular polygon is shown with one of its angle measures labeled a. If m∠a = (2z + 64)°, find the value of z.
Answer:
the sum of all the angles of the polygon is 180°
Then,
(2z+64)° = 180°
2z = 180° - 64°
2z = 116°
z = 116 / 2
= 58° (ans)
