#Rate of change
Rate of change is slope
If two points be (x1,y-1) and (X2,Y2) then
If a line be ax+by+c=0
#X and y inetercept
If a equation given y=mx+b
- To find x intercept put y=0
- To find y inetercept put x=0
#Zeros
To find the zeros spot out the x inetercepts
The x values of the x intercepts are the zeros
In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0
End behavior:
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
Answer:
8
Step-by-step explanation:
Mai has $36 and each movie ticket is $4.50.
You wanna divide 36 by 4.50 to find out how much tickets she can purchase which is 8.
Answer:
Step-by-step explanation:
4(x + 7) = 38
Since there is no operation sign between the 4 and parenthesis, it makes it an automatic multiplication problem.
You would use distributive property to multiply each which should leave your equation looking like this afterwards:
4x + 28 = 38
(4 times x and 4 times 7)
You would then solve it like a two step equation,
1. +28 - 28 = 0
2. 38 - 28 = 10
4x = 10
10 divided by 4 = 2.5
x = 2.5
We can recheck our work by substituting in the value of x.
4(2.5 + 7) = 38
10 + 28 = 38
When we substituted in the value, it gave us the correct inequality.
Therefore,
x = 2.5
