What is the average rate of change of f(x) from −2 to 2?
Answer: -4
Step-by-step explanation:
Average rate of change is the slope (m) between the two coordinates (-2, 25) and (2, 9).
Answer: Its true that it but equals 7
Step-by-step explanation:
B: Contraction
C: Translation
D: Diagram
Answer: A: Expansion
Step-by-step explanation:
Given: A 24 inch x 30 inch poster is made from a picture that is 4 inch x 5 inch.
Thus, the dimension of the image = 24 inch x 30 inch
The dimension of pre-image = 4 inch x 5 inch.
We know that the scale factor of dilation is given by :-
Since, k>1, therefore the given dilation is an example of expansion because the dimension of the image is greater than the dimension of pre-image.
Which steps would allow him to eliminate the y terms in the system of equations?
Multiply 2x+3y=−1 by 3. Multiply 3x−5y=10 by 5. Add the resulting equations together.
Multiply 2x+3y=−1 by 3. Multiply 3x−5y=10 by 2. Add the resulting equations together.
Multiply 2x+3y=−1 by 2. Multiply 3x−5y=10 by 5. Add the resulting equations together.
Multiply 2x+3y=−1 by 5. Multiply 3x−5y=10 by 3. Add the resulting equations together.
Answer:
Multiply 2x + 3y = −1 by 5. Multiply 3x − 5y = 10 by 3. Add the resulting equations together.
Step-by-step explanation:
To eliminate the y-term. we must multiply both equations by values that make the coefficients of y opposite in sign.
2x + 3y = -1 (1)
3x - 5y = 10 (2)
The easiest way to do this is to multiply Equation (1) by 5
and Equation (2) by 3.
5 × [2x + 3y = -1]
3 × [3x - 5y = 10]
Then, add the two equations.
10x + 15y = -5
9x - 15y = 30
19x = 25
Conclusion: Multiply 2x + 3y = −1 by 5. Multiply 3x − 5y = 10 by 3. Add the resulting equations together.
A. 123.9 m²
B. 12.4 m²
C. 61.9 m²
D. 49.5 m²
Answer:
61.9
Step-by-step explanation:
center center is 72 degree for each triangle
the distance of center to the side h=3/tan 36=4.12,
area=5* (4.12*6)/2=61.94==61.9
