Answer:
You have a stand that sells bags of oranges. 25lb sells for $5. You sell 3 bags. How much money did you make?
3 * 5 =$15
Step-by-step explanation:
You have a stand that sells bags of oranges. 25lb sells for $5. You sell 3 bags. How much money did you make?
3 * 5 =$15
How generous
x+3=8
minus 3 both sides
x+3-3=8-3
x+0=5
x=5

Step-by-step explanation:
This is the first step to do in order to be able to properly add the fractions.
Answer:
k = 13The smallest zero or root is x = -10
Step-by-step explanation:
you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
Answer:
Average rate of change for the function 
over the interval -1<x<1 is -1
Step-by-step explanation:
We need to find average rate of change of f over the interval -1 < x < 1
The function given is:
The formula used to find average rate of change is:
We have, a = -1 and b = 1
Finding f(b) when b=1
Now, finding f(a), when a= -1
Now, putting values and finding average rate of change
So, average rate of change for the function over the interval -1<x<1 is -1
