Answer:

y=x+15

Step-by-step explanation:

1. find the slope

m=(24-19)/(9-4)

m=5/5

m=1

2. plug slope into slope intercept formula

y=1x+b

y=x+b

3. plug in for x and y from either coordinate point (just make sure they are from the same point!!)

24=9+b

15=b

4. plug m and b into formula

y=x+15

If you looking for the amount of beans

25 = 16.75 + 1.50×b

25-16.75 = 1.50b

8.25 = 1.50b

8.25/1.50 = b

b = 5.5

Please help me, I have no idea what the equation for the new path is. <br><br> Thank you!!
Citrus2011 [14]
First, find the slope of the initial line; 

m=(y₁-y₂)/(x₁-x₂) 

m=(4-0)/(11-8) 
m=4/3 

If two lines are parallel, the slope is the same although the intercept can differ. 

If this parallel lines passes through the point (4, 5); 

y=(4/3)x+c <-- plug in coordinates to solve for c
5=(4/3)(4)+c 
(15/3)=16/3+c 
(15/3)-(16/3)=c 
-1/3=c 

Therefore, the final equation should be y=4/3x-1/3

Hope I Helped :)

For the function f(x)=5x^2-7x, what is f(-3)?
Ainat [17]

Answer:

24

Step-by-step explanation:

f(x)=5x^2-7x

substitute x to 3

f(3)=5(3)^2-7(3)

f(3)=5(9)-21

f(3)=45-21

f(3)=24
