Answer:
26
Step-by-step explanation:
given f(x)=3(2-x)+5 what is the value of f(-5)?
f(x)=3(2-(-5))+5 x minus a negative is a plus 2 - -5 = 2 +5
= 3(7) + 5
= 21 +5
= 26

Part A
The graph passes through .
If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points.
Using and .
We obtain the slope to be
Using and .
We obtain the slope to be
.
Since the slope is not constant(the same) everywhere, the function is non-linear.
Part B
A linear function is of the form
where is the slope and is the y-intercept.
An example is
A linear function can also be of the form,
where and are constants.
An example is
A non linear function contains at least one of the following,
- Product of and
- Trigonometric function
- Exponential functions
- Logarithmic functions
- A degree which is not equal to or .
An example is or or etc
Answer:
83 in²
Step-by-step explanation:
To calculate, add the areas of all three shapes that make up the polygon.
Area of rectangle = L×W = 5×8 = 40 in².
Area of top triangle = 1/2×b×h = 1/2×8×7=28 in².
Area of triangle on the right = 1/2×6×5 = 15 in².
Total area = 40+28+15 = 83 in²
5 2/3 would be 3 times 5 +2 think of it as starting the letter C from the bottom to the top multiply the bottom and middle add the top
If you do that you should get 17/3
