Anwser: -23
Step-by-step explanation:
I knew that because i just did negative and positive numbers on a number line
Answer:
It's y = (5)(0.2)^x
_____________
Step-by-step explanation:
Exponential functions have a standard form of ab^x
Where a is the starting value, and b is the exponential growth or decay.
Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.
We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.
So the answer must be the second choice.
Add two like terms: 16x+(-9x)=7x
Add 15 to both sides: 7x=28
Divide 7 on both sides: x=4
Part A: the value of x is 0 because anything to the zero power is 1
part B: x can be any number. 6 to the 0 power is 1 and 1 to any power is 1
Answer: 6,8 and 10
Step-by-step explanation:
To find the length , all we need to find is the distance between each point ,
the formula for calculating distance between two points is given by :
D = 
Let the points be :
A ( -5,-1)
B(-5,5)
C(3,-1)
Calculating the length AB , we have
D1 = 
D1 = 
D1 = 
D1= 6
Calculating the length AC , we have
D2 = 
D2 = 
D2 = 
D2 = 8
Calculating the length BC , we have
D3 = 
D3 = 
D3 = 
D3 = 10
Therefore ,the length of the sides of the triangle are 6,8 and 10
