Answer:
I don't understand your question but thanks for the points ;) Kinda sucks when someone does it to you, right? Maybe you should stop commenting it on other people's questions so they can get the help they need
Answer:
The given table represents a function f(x) = y = 2x+3
The upper graph
Step-by-step explanation:
We will write the equation of the right line in the explicit (slope) form
y = ax+b
We will take two points from the given table
A(-1,1) and B(0,3) and insert their coordinates in the equation y=ax+b and get
A(-1,1) => 1 = (-1)*a+b => -a+b=1
B(0,3) => 3=0*a+b => 3= 0+b => b=3
Now we will insert b=3 in the equation -a+b=1 and get
-a+3=1 => a=3-1 => a=2
Now we will insert a=2 and b=3 in the equation y=ax+b and get
equation of the function
y = 2x+3 = f(x) The upper graph.
Good luck!!!
Answer:
10.11 feet
Step-by-step explanation:
Let H ft be the elephant's height and x ft be the initial distance from naturalist to the elephant.
1. Naturalist takes a view to find the a 22 degree angle of elevation, then

2. Naturalist moves backwards from the elephant pacing off a distance of 27 feet, the distance from naturalist to the elephant becomes (x+27) ft. He takes a second view and determines a new angle of elevation of 11 degrees. Then

3. Solve the system of two equations:

Then

Mr Welch bought 8 yard of fencing
Step-by-step explanation:
Mr Welch bought 24 ft of fencing
We need to find how many yards of fencing did he buy
We need to convert 24ft into yards
We are given 1 yd = 3ft
We can write
3 ft = 1 yd
then 1 ft will be:
1 ft = 1/3 yd
Now, 24 ft will be:
24 ft = 1/3*24
24 ft = 8 yard
So, Mr Welch bought 8 yard of fencing

Answer:
x < 8
Step-by-step explanation:
8x + 3 < 67
8x < 64 (-3)
x < 8 (÷8)
