Answer is a. (-13, 12) b. (4, 11)
Step by step
When your rule is
(x,y) ➡️ (x -8, y +2)
a)
You take your input (-5, 10) and add your input rule to that input to get your output.
Input of x is -5, add x rule -8 = -13
Input of y is 10, add y rule +2 = 12
Your output or new coordinate is (-13, 12)
b) You take your input (12, 9) and add your input rule to that input to get your output.
Input of x is 12, add x rule -8 = 4
Input of y is 9, add y rule +2 = 11
Your output or new coordinate is ( 4, 11)
If your rule changes the process is still the same. Remember to watch adding or subtracting negatives. You can use a graph and plot your input and count out your “rule” to double check your work if you want.
Answer:
Slope-Intercept Form of a Line (y = mx + b)
Step-by-step explanation:
The slope-intercept is the most “popular” form of a straight line. Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form.
Answer:
(A)increasing
Step-by-step explanation:
Given the time and total distance ran by Myra in the table below.
We observe that as time increases, Myra's distance also increases. It is the speed(0.2 miles per minute) which is constant.
Therefore Option A is the correct option.
The formula for the volume of a triangular pyramid is:
V=1/3AH (where A=area of the base and H=height)
The formula for the volume of a triangular prism is:
V=AH (where A=area of the base and H=Height)
Since the base and the height are the same in this problem for both the prism and the pyramid, solving for the volume of the prism is simple.
Looking at the formulas, you'll see that the volume of the pyramid (assuming that both the height and the area of the base are the same) is 1/3 the volume of the prism.
V(pyramid)=1/3V(prism)
Now lets input the volume of the pyramid
26cm³=1/3 V(prism)
Divide both sides by 1/3
78cm³=V(prism)
Answer=78cm³
