Rate of change is the slope of the line.
Slope = change in y over the change in x.
Slope = (7 - -3) / ( -2 -8)
Slope = 10/-10
Slope = -1

Donna worked for 13 hours each day for 6 days. Then the next day she worked 7 hours. How many hours did Donna work in all?
Answer:
85 hours
Step-by-step explanation:
Multiply 13 by 6 to know how much she worked in those 6 days and then add 7 more hours to that and you should get 85 hours in total.
Answer: 85 hours
Step-by-step explanation:
Donna worked for 13 hours every day for 6 days:
This means that she worked 13 hours each day so what we have to do is this:
13·6 = 78 <------- That is the amount of hours she worked for 6 days
Now we have to figure the last day:
Donna worked 7 hours.
This part is simple, all we have to do is add 78 from our previous equation and add it to 7 hours which gives us a total of 85 hours!
Hope this helps :)

What is Exterior angle sum?A triangle's exterior angles add up to 360 degrees. The angle that is created between one of a triangle's sides and its adjacent extended side is known as the external angle. A triangle has three external angles.
Sum of all the exterior angles of a triangle = 360°
Given:
Exterior <A= 9x+ 1
Exterior <B= 5x+ 12
Exterior <C= 10x - 37
As, we know Sum of exterior angle of a triangle is 360 degree.
So, 9x + 1+ 5x+ 12 + 10x - 37 = 360
24x - 24= 360
24x= 384
x= 16
Hence, the value of x is 16.

Answer:
416 passengers
Step-by-step explanation:
Dont stress out, it’s just simple subtraction,
so A380 can transport 555 which is 139 more then 747
so subtract 555-139 which will give you 416 passengers.

solve for x. 4(2-x)+13=2x+3
Answer:
x = 3
Step-by-step explanation:
4(2-x)+13=2x+3
distribute the 4.
8 - 4x + 13 = 2x + 3
combine like terms.
21 - 4x = 2x + 3
18 = 6x
divide by 6.
x = 3
check.
4(2 - 3) + 13 = 2(3) + 3
4(-1) + 13 = 6 + 3
-4 + 13 = 9
9 = 9

Ninety-three percent of a town’s population owns cars. If the number of cars owned is 5,208, what is the population of the town?
You have 2 attempts left to earn the full credit for this problem.
Answer:
5600
Step-by-step explanation:
Let p represent the number of people in the town. If we assume that each car owner owns only one car, then we have ...
0.93p = 5208
p = 5208/0.93 = 5600
The population of the town is 5600.

What is the equation of the line that has a slope of 5 and goes through the point (2,7)
Answer:
y= 5x-3
Step-by-step explanation:
It works with the y=mx+b form. 5 is slope so it is m, and when u do 5(2)=10. In order to get to 7 u must subtract 3, so the answer is y=5x-3! Ur welcome!
The equation of the line that has a slope of 5 and goes through the point (2,7) is y-5x = -3
The formula for calculating the equation of a line in point-slope form is expressed as:
[tex]y-y_1 = m(x-x_1)[/tex]
m is the slope of the line
(x1, y1) is any point on the line
Given the following parameters
m =5
(x1, y1) = (2, 7)
Substitute the parameters into the given formula;
y - 7 = 5(x - 2)
y - 7 = 5x - 10
y - 5x = -10 + 7
y - 5x = -3
Hence the equation of the line that has a slope of 5 and goes through the point (2,7) is y-5x = -3

Solve the following equation for y. 4x - 6y - 8 = 0
Answer:
y = 2/3x + -4/3
Step-by-step explanation:
4x - 6y - 8 = 0 (Add -4x to both sides)
-6y - 8 = 4x (Add 8 to both sides)
-6y = 4x + 8 (Divide -6 from both sides)
y = 2/3x + -4/3
