Answer:
A. 16
Step-by-step explanation:
We have to find rate of change of function from x=3 to x=5
The average rate of change for the interval a≤x≤b is given by:
Rate of change= (f(b)-f(a))/(b-a)
In our question,
a=3
and
b=5
We can see from the table that at x = 3, the value of function is 18
So,
f(a)=18
and
At x=5, the value of function is 50
f(b)=50
Rate of change=(50-18)/(5-3)
=32/2
=16
So the rate of change of function between x=3 and x=5 is 16 ..
Option A is the correct answer..
3x-9x+3(3.2)=1
3x-9x+9.6=1
-9.6. -9.6
-6x=-8.6
X=-8.6/-6=1.433333333
Answer:
(2x+3)(x - 1)
Step-by-step explanation:
Since there is no common number to factor by we must approach this problem differently:
Step 1:
Multiply leading coefficient (2) by the constant term (-3)
2 x -3 = -6
Step two:
Find two numbers that multiply to -6 but add to the middle coefficient (1).
You should find these numbers to be 3 and -2
Step 3:
Replace 1x in the equation with your found numbers
2x^2 - 2x + 3x - 3
Step 4:
Take out the greatest common factor from the first two numbers, and the last two numbers.
For 2x^2 - 2x the greatest common factor would be 2x
For 3x - 3 the greatest common factor would be 3.
Step 5:
Factor out the found common factors
2x(x-1) + 3(x-1)
The values inside the bracket should be the same.
Step 6:
Factor out (x-1)
(x - 1)(2x + 3)
Therefore the factored form is (2x + 3)(x - 1)
Answer:
Use the Triangle Sum Theorem (all three angles inside a triangle add up to 180 degrees)
A is 27, C is 90 degrees (right angle) , B is unknown.
Now add. 117+B=180
B is 63 degrees.
D is 31 degrees, E is 90 degrees. F is unknown.
Add.
31+90+F=180
121+F=180
F is 59.
